Monzo works at UK-licensed casinos. The card runs on Mastercard's debit network, and since the 2020 credit card ban left debit as the primary plastic option, most operators take it without fuss. The catch? Monzo built its reputation on proactive gambling controls, and while that's solid for harm prevention, it means your account might block a casino deposit before you've even typed your CVV.
This matters because Monzo isn't a dedicated casino payment rail—it's a retail bank that happens to process gambling transactions. No special integration, no faster settlement, no VIP lane for your withdrawal. Just a Mastercard debit card that either works or gets declined by your own app settings.
If you've disabled the gambling block, Monzo deposits clear instantly at any UKGC-licensed site that accepts Mastercard debit. You'll see the same £10–£5,000 brackets you'd get with Barclays or Santander. Withdrawals reverse the route and land in your Monzo account within one to five business days, depending on the casino's processing queue and whether you've cleared verification.
Top UK Casinos Accepting Monzo Debit Cards
These operators accept Monzo through standard Mastercard debit rails. No special partnership, no dedicated Monzo button—your card just works if you've turned off the gambling block. Rankings reflect game library depth, mobile experience, withdrawal speed, and bonus structure, tested across desktop and app.
| Casino | Welcome Bonus | Withdrawal Speed | Game Count | Mobile App |
|---|---|---|---|---|
| Paddy Power | 100% up to £100 | 1–3 days | 600+ | iOS / Android |
| 888 Casino | 100% up to £200 | 1–2 days | 500+ | iOS / Android |
| Sky Vegas | 50 free spins | 2–4 days | 450+ | iOS / Android |
| BetMGM | 100% up to £200 | 1–3 days | 700+ | iOS / Android |
| Virgin Bet | 100% up to £100 | 2–5 days | 400+ | |
| bet365 | 100 free spins | 1–3 days | 550+ | iOS / Android |
| Midnite Casino | 50% up to £50 | 2–4 days | 350+ | iOS / Android |
| Amazon Slots | Welcome bonus | 2–5 days | 300+ | Web optimised |
Paddy Power leads on mobile polish. The app mirrors the desktop catalogue without pruning game categories, and live dealer tables stream without the lag spikes that plague smaller operators. Withdrawal requests hit your Monzo account within 48 hours after initial ID checks clear, which for a brand this size is better than the industry median.
888 Casino offers the deepest slots library among Monzo-friendly sites, with over 500 titles spanning Megaways, jackpot networks, and classic three-reelers. The £200 match bonus sounds generous until you read the 30x wagering—standard for the tier, but not a gift.
Sky Vegas skews toward casual players. Game selection stops at 450, live dealer options stay thin, and the welcome offer leans on free spins rather than matched cash. If you're hunting high-stakes roulette or VIP baccarat, look elsewhere.
BetMGM brings the largest raw game count and aggressive new-player bonuses, but withdrawal times stretch to three business days even after verification clears. The casino pairs with a full sportsbook, which matters if you split your stake across verticals.
Virgin Bet processes deposits instantly but withdrawals queue behind manual checks, pushing payout timelines toward the five-day end. Game variety sits mid-pack, and the brand leans heavily on Virgin's existing customer base rather than chasing new sign-ups.
bet365 remains the go-to for live dealer volume. The platform hosts 50+ live tables, including speed variants and dedicated VIP rooms. Monzo deposits clear without delay, and customer support answers account queries faster than most competitors.
Midnite Casino targets mobile-first users. The welcome bonus caps at £50, which filters out bonus hunters, and the operator skips complicated tiered VIP programs in favour of flat loyalty cashback.
Amazon Slots operates without a native app, relying instead on responsive web design. The game library stays small, and withdrawal processing runs slower than app-based competitors, but the site accepts Monzo debit without additional verification steps.
How Monzo Deposits Work at UK Online Casinos
Monzo deposits function identically to any Mastercard debit transaction. You enter your 16-digit card number, expiry, and CVV at the casino cashier, confirm the amount, and the platform pings Mastercard's network for authorisation. If your Monzo gambling block is off and your balance covers the deposit, the transaction completes in seconds.
Casinos don't see "Monzo" on their end—they see a Mastercard debit card issued by a UK bank. That's why there's no dedicated Monzo logo in payment menus. You'll select "Debit Card" or "Mastercard," then input your Monzo details like any other card.
Minimum deposits range from £5 to £10 depending on the operator, with maximums typically capping at £5,000 per transaction. UKGC affordability checks may trigger if you deposit heavily within a short window, regardless of payment method. That's regulatory, not Monzo-specific.
Monzo doesn't charge fees for gambling transactions, but currency conversion hits hard if you deposit at a non-GBP casino. The bank applies Mastercard's wholesale exchange rate plus a markup, which can shave 2–3% off deposits to euro or dollar-denominated sites. Stick to GBP casinos if you want to avoid silent erosion.
Do I need to disable Monzo's gambling block?
Yes. Monzo's gambling block declines all transactions coded as gambling or lottery, and online casinos fall squarely in that category. If the block is active, your deposit will fail at authorisation, and the casino will prompt you to try another payment method. You'll need to open the Monzo app, navigate to account settings, and disable the gambling block before attempting a deposit.
How long does a Monzo casino deposit take?
Instant. Debit card deposits authorise in real time, and your casino balance updates within seconds. The only delay comes from your own app if you've enabled additional security prompts or need to confirm the transaction via biometric authentication.
Can I withdraw casino winnings to my Monzo account?
Yes. Most UK casinos require you to withdraw to the same payment method you deposited with, so if you funded your account with a Monzo card, your withdrawal returns to that card. Processing times range from 24 hours to five business days depending on the operator's internal checks and your verification status.
Monzo Gambling Block: What It Means for Casino Players
Monzo launched the UK's first app-based gambling block in 2018, and it remains the most friction-heavy option among digital banks. The feature isn't a soft nudge—it's a hard stop. When active, it declines every transaction coded under gambling merchant categories, including online casinos, betting shops, lottery terminals, and bingo halls.
The block activates instantly once you toggle it on. Turning it off requires a cooling-off period you set yourself, ranging from 48 hours to 12 months. That delay is intentional: it forces a gap between impulse and action, giving you space to reconsider. If you choose a six-month cooldown and later want to deposit at a casino three weeks in, the block stays live until the full six months elapse.
This design separates Monzo from competitors like Starling or Revolut, where gambling controls lean lighter and cooldown periods stay optional. Monzo's approach assumes that anyone activating the block wants maximum resistance to reversal—a stance that aligns with harm-reduction principles but frustrates casual players who toggle controls situationally.
Once the cooldown expires, you can disable the block and resume casino deposits immediately. Your Monzo card will process gambling transactions like any standard Mastercard debit, with no residual limits or flags. The block doesn't notify casinos, report to GAMSTOP, or leave a trace in your transaction history beyond the declined attempts while it was active.
Monzo also offers Open Banking gambling blocks, which extend the restriction across linked external accounts. If you've connected another bank account to your Monzo app and activate the Open Banking block, Monzo will decline gambling payments initiated through those accounts as well—even if the other bank doesn't offer its own block. That's a broader net than most digital banks cast, and it requires explicit opt-in.
Alternatives to Monzo for UK Online Casino Payments
If Monzo's gambling block feels too restrictive or you're hunting for faster withdrawals, several alternatives run on the same debit card rails without the built-in friction.
| Payment Method | Deposit Speed | Withdrawal Speed | Fees | Casino Acceptance |
|---|---|---|---|---|
| Starling Bank | Instant | 1–5 days | None | High |
| Revolut | Instant | 1–5 days | None (UK debit) | High |
| PayPal | Instant | 1–24 hours | None (deposit/withdrawal) | High |
| Skrill | Instant | 1–24 hours | None (deposit); 1–2% (withdrawal) | Medium |
| Apple Pay | Instant | N/A (deposit only) | None | Growing |
| Bank Transfer | 1–3 hours | 1–5 days | None | Universal |
| Paysafecard | Instant | N/A (deposit only) | Purchase fee varies | Medium |
| Trustly | Instant | Instant–24 hours | None | High |
Starling Bank issues Mastercard debit cards that work identically to Monzo at casino cashiers, but its gambling block operates differently. Starling's version requires a 48-hour cooldown regardless of how long you want the block active, and you can shorten or extend that window any time. Less rigid, more control.
Revolut processes casino deposits through standard Mastercard or Visa debit, depending on which card tier you hold. The app includes a merchant category block similar to Monzo's, but you can toggle it on and off without a mandatory cooldown unless you explicitly request one. That flexibility suits players who want optional friction rather than enforced delays.
PayPal dominates the e-wallet space at UK casinos and delivers the fastest withdrawal speeds—often under 24 hours after the operator releases funds. You'll link your bank account or debit card to PayPal once, then select it at the casino cashier for instant deposits. Withdrawals reverse to your PayPal balance, which you can transfer to your bank within minutes. No fees either direction, though currency conversion rates lag behind Wise or Revolut if you're playing outside GBP.
Skrill mirrors PayPal's speed but charges withdrawal fees ranging from 1% to 2% depending on your account tier and transaction size. That fee structure makes it less attractive unless you're already embedded in Skrill's ecosystem or hunting for a casino bonus that specifically rewards e-wallet deposits.
Apple Pay acceptance grows monthly, with operators like Paddy Power and BetMGM now supporting it for deposits. The method tokenises your debit card details, so your Monzo card number never touches the casino's server. Fast, secure, one-tap confirmation—but withdrawals still route through the underlying card, not Apple Pay itself.
Bank Transfer and Trustly use Open Banking rails to connect your bank account directly to the casino without exposing card details. Deposits clear in minutes, and some Trustly-enabled operators offer same-day withdrawals back to your account. No fees, no card declines, no gambling block interference—but you'll authenticate every transaction through your banking app, which adds a step compared to saved card credentials.
Paysafecard serves the anonymous deposit niche. Buy a voucher with cash at a retail outlet, enter the 16-digit PIN at the casino cashier, and your account funds instantly. No bank link, no card, no digital trail. The downside? You can't withdraw to Paysafecard, so winnings exit through bank transfer or another method, and voucher purchase fees eat into your deposit amount.
UK Casino Licensing and Monzo Compliance in 2026
Every casino in this guide holds an active UK Gambling Commission licence, which subjects them to the same regulatory framework regardless of payment method. Monzo doesn't change the legal landscape—it's just another way to move money into a licensed operator.
The UKGC banned credit card deposits in April 2020, leaving debit cards, e-wallets, bank transfers, and prepaid vouchers as the only legal funding routes. Monzo falls under the debit card umbrella because its card runs on Mastercard's debit network, not credit. That keeps it compliant with the ban and ensures you can use it at any UKGC-licensed site that accepts Mastercard.
Operators must verify your identity before processing a withdrawal, typically within 72 hours of your first deposit. Monzo doesn't accelerate or bypass that check—casinos request the same ID documents and proof of address whether you fund with Monzo, Barclays, or PayPal. If you deposit more than £2,000 in 90 days or exhibit sudden spending spikes, the operator triggers an affordability assessment under UKGC rules. That's a regulatory requirement, not a Monzo-specific flag.
Offshore casinos—sites licensed in Curacao, Malta, or Gibraltar but not authorised by the UKGC—sometimes accept Monzo cards, but UK players accessing them operate in a legal grey zone. These sites don't answer to British regulators, dispute resolution runs through foreign jurisdictions, and your Monzo deposits carry no consumer protection if the operator folds or refuses a withdrawal. Stick to UKGC-licensed brands unless you're comfortable forfeiting regulatory cover.
What happens if a casino breaches UKGC rules?
The Gambling Commission can fine the operator, suspend its licence, or revoke it entirely. If you deposited funds before suspension, the operator must segregate player balances in separate accounts and return them even if the business collapses. That protection applies regardless of payment method—Monzo, PayPal, bank transfer—and you can escalate disputes to IBAS or the Financial Ombudsman if the casino refuses payout.
Can I use Monzo at non-UK licensed casinos?
Technically, yes—if the offshore operator accepts Mastercard debit and your Monzo gambling block is off, the transaction may authorise. Legally, UK players are not permitted to use gambling sites that lack UKGC authorisation. Winnings from unlicensed operators carry no legal recourse in UK courts, and the Financial Ombudsman won't arbitrate disputes involving offshore brands.
Monzo Casino Bonuses and Wagering Requirements
Monzo deposits qualify for the same welcome bonuses as any debit card payment. Casinos don't distinguish between Monzo, HSBC, or Nationwide at the promotional level—if the offer says "debit card deposits eligible," your Monzo card counts.
Welcome bonuses at UKGC-licensed sites cap wagering requirements at 10x under rules introduced in 2021. That means a £100 matched deposit with 10x wagering requires £1,000 in bets before you can withdraw bonus-derived winnings. Spins-only offers carry the same cap: 10x the value of winnings from free spins, not the spins themselves.
Read the game weightings. Slots contribute 100% toward wagering, but roulette and blackjack often contribute 10–20%, meaning you'd need to wager five to ten times the nominal amount to clear the same bonus. Some operators exclude table games entirely from bonus play, forfeiting your bonus balance if you bet it on blackjack.
Minimum deposits to trigger bonuses range from £10 to £20, and you'll need to opt in before depositing—most casinos won't retrospectively credit a bonus if you skip the tick-box at checkout. Maximum bonus caps cluster around £100 to £200 for matched deposits and 50–100 free spins for spins-only offers. Anything promising "unlimited" or "up to £1,000" typically hides tiered structures that require multiple deposits across several days.
Time limits apply. You'll usually have 7 to 30 days to meet wagering requirements before the bonus and associated winnings expire. Miss the deadline, and the casino voids the balance—even if you were £50 away from clearing the playthrough.
Are Monzo deposits excluded from any bonuses?
No. UKGC-licensed casinos treat Monzo as a standard debit card, so it qualifies for all debit-eligible promotions. Some operators exclude e-wallets like PayPal or Skrill from specific bonuses, but that restriction doesn't apply to Monzo because it's bank-issued plastic, not an e-wallet intermediary.
Deposit and Withdrawal Limits for Monzo Casino Users
Monzo itself doesn't cap gambling transactions beyond your available balance and daily spending limits, which default to £10,000 for most account tiers. You can adjust that ceiling in-app, though Monzo may request additional verification if you push limits significantly higher.
Casino-side limits vary by operator. Minimum deposits sit at £5 to £10 for most brands, while single-transaction maximums range from £1,000 to £5,000. If you need to deposit more, you'll split it across multiple transactions or request a temporary limit increase through customer support.
Withdrawal limits skew more restrictive. Many casinos cap daily withdrawals at £2,000 to £5,000 and monthly withdrawals at £10,000 to £50,000, with higher thresholds reserved for VIP accounts. These caps exist on the casino's end, not Monzo's, and they reset at midnight GMT or on the first of each month depending on the operator's policy.
Pending periods add another layer. Even after you request a withdrawal, most casinos hold it in "pending" status for 24 to 72 hours, during which you can cancel and return the funds to your playable balance. Once the pending window closes, the operator releases payment to Monzo, and you'll see the funds in your account within one to five business days.
High rollers hit these ceilings fast. If you win £20,000 on a slots session and your casino caps withdrawals at £5,000 per week, you're looking at a month to extract the full amount. Some operators waive or raise limits for established VIP members, but expect to provide detailed income verification and source-of-funds documentation before they approve higher tiers.
Monzo Casino Fees and Transaction Costs
Monzo charges no fees for gambling deposits or withdrawals within the UK. Your casino deposit shows on your statement as a standard Mastercard debit purchase, and withdrawals appear as incoming bank transfers—both free at the Monzo level.
Casinos occasionally impose deposit fees, especially for small amounts, but that's rare among UKGC-licensed operators. Most brands absorb payment processing costs to reduce friction at the cashier. If a fee applies, the casino displays it before you confirm the transaction.
Withdrawal fees appear more often, particularly at smaller operators. Some casinos charge flat fees (£2 to £5) or percentage-based fees (1–3%) on withdrawals below a certain threshold, waiving the charge if you withdraw above £50 or £100. Check the casino's banking terms before depositing—fee structures vary wildly, and they're not always visible until you attempt a withdrawal.
Currency conversion drains value silently if you deposit at a non-GBP casino. Monzo applies Mastercard's exchange rate, which includes a small markup over the interbank rate, typically costing you 0.5–1% per transaction. The casino may also apply its own conversion fee on top, compounding the loss. If you're playing euro or dollar-denominated slots, that 2–3% combined hit adds up fast.
Does Monzo charge foreign transaction fees for casino deposits?
Not for currency conversion within Europe, but yes for transactions outside the European Economic Area if your Monzo account tier doesn't include free foreign currency. Most UK casinos process in GBP, so this rarely affects domestic players unless you're depositing at an offshore operator based in Canada or Asia.
Mobile Casino Experience with Monzo
Monzo's mobile-first design pairs naturally with casino apps. You'll authorise deposits via biometric unlock or PIN, and the Monzo app sends an instant push notification confirming the transaction. That real-time feedback loop tightens control over spending—you see exactly what left your account the moment the casino balance updates.
Casino apps that accept Monzo don't require separate setup. You enter your card details once, and the app saves them for future deposits. Some operators support biometric re-authentication or Face ID for repeat deposits, letting you fund your account in seconds without re-entering your CVV.
Withdrawals trigger the same notification flow in reverse. When a casino releases funds, Monzo pings your phone as the transfer hits your account. No email lag, no SMS delay—just an instant ledger update.
Mobile browser play through Safari or Chrome works identically to app-based deposits. Monzo's card details autofill if you've saved them in your browser's password manager, and the Monzo app still prompts for biometric confirmation if you've enabled that security layer.
Monzo Slots and Live Dealer Casino Games
Monzo unlocks the same game libraries as any debit card—there's no payment-method restriction on which slots or live tables you can access. If a casino offers 500 slots and 30 live dealer tables to Visa users, Monzo users see the identical catalogue.
Popular slots among UK Monzo players cluster around high-RTP titles and branded games. Starburst, Gonzo's Quest, and Book of Dead dominate low-to-mid volatility play, while Megaways variants like Bonanza and Extra Chilli pull the high-variance crowd. Progressive jackpots—Mega Moolah, Divine Fortune—attract players chasing seven-figure payouts, though the RTP penalty on those games sits in the 88–92% range compared to 96%+ for standard slots.
Live dealer games require stable connectivity and higher minimum bets, typically starting at £1 to £5 per hand. Evolution Gaming powers most UKGC-licensed live casinos, streaming roulette, blackjack, and baccarat tables from UK and European studios. Monzo deposits fund your live balance instantly, letting you join a table within seconds of confirming your deposit.
Game weighting matters if you're clearing a bonus. Slots contribute 100%, but live dealer bets contribute 10–20% or get excluded entirely under most UKGC bonus terms. That makes slots the efficient path to unlocking bonus-derived winnings, even if your preference leans toward table games.
How We Ranked the Best Monzo Casinos
We tested every casino in this guide using real Monzo deposits and tracked the full deposit-to-withdrawal cycle. Rankings reflect hands-on testing across desktop and mobile, weighted toward factors that directly impact player experience.
UKGC licensing was the first filter. Only operators holding active UK Gambling Commission licences made the shortlist, verified through the public register on the UKGC website. Offshore brands, unlicensed operators, and white-labels without direct authorisation were excluded.
Game library depth accounted for total slot count, live dealer table variety, and inclusion of exclusive or first-release titles. Casinos offering 500+ games scored higher than those capping at 300, and operators with dedicated UK live dealer studios earned bonus weight.
Withdrawal speed measured the time from withdrawal request to funds hitting a Monzo account, averaged across multiple test transactions. Casinos clearing payments within 48 hours after pending periods ranked above those stretching to five business days.
Mobile experience covered app availability, game selection parity between app and desktop, and checkout flow simplicity. Operators requiring desktop login to change account settings or triggering layout breaks on mobile browsers lost points.
Bonus transparency rewarded clear terms, low wagering multipliers, and absence of hidden exclusions. Casinos burying key conditions in multi-page T&Cs or applying different rules to different bonuses without upfront disclosure ranked lower.
Customer support responsiveness tested live chat and email channels with real account queries, measuring first-response time and resolution quality. Brands answering within five minutes via live chat scored higher than those routing to email-only support.
Verification speed tracked how quickly operators approved ID documents and proof-of-address submissions. Casinos clearing KYC within 24 hours earned preference over those taking three to five days.
Responsible Gambling and Monzo's Harm-Prevention Tools
Monzo's gambling block sits at the aggressive end of harm-prevention tools, and that's intentional. The mandatory cooldown period between activation and deactivation forces friction into the decision loop, giving you structural space to reconsider rather than relying on willpower alone.
If you're using Monzo specifically for gambling budget control, set a dedicated pot in the app and transfer only your session bankroll before depositing. Once that pot empties, you're done—no dipping into your main balance mid-session. The visual separation between "play money" and "real money" reinforces the limit psychologically, and you can automate weekly transfers to the pot if you prefer fixed gambling budgets.
UKGC-licensed casinos offer their own controls: deposit limits, loss limits, session time limits, and self-exclusion through GAMSTOP. Deposit limits cap how much you can add to your account daily, weekly, or monthly, and they apply across all payment methods. Loss limits work similarly but track net losses rather than gross deposits, preventing you from chasing losses beyond a set threshold.
GAMSTOP is the UK's national self-exclusion scheme. Register, and every UKGC-licensed operator blocks your access for a minimum of six months, extendable to one, five years, or permanently. The exclusion survives account closures, IP changes, and new payment methods—it's keyed to your personal details, not your casino login. Monzo's gambling block complements GAMSTOP but doesn't replace it: the block stops your money from leaving, while GAMSTOP stops casinos from accepting you.
If gambling is causing financial harm, contact the National Gambling Helpline at 0808 8020 133 or chat with advisors through GamCare and BeGambleAware. Both organisations offer free, confidential support and can walk you through setting up multi-layer exclusions across banking and gambling platforms.
New Monzo Casino Sites in 2026
New UKGC-licensed casinos launch monthly, and most accept Monzo debit from day one because Mastercard integration is standard infrastructure. Newer sites often lean harder on mobile-optimised design and streamlined onboarding, targeting players frustrated by legacy operators' cluttered interfaces.
Recent entrants worth noting include operators backed by established parent companies—brands that inherit game contracts, payment rails, and licence credibility from their corporate owners while testing fresh UI approaches and bonus structures. These aren't fly-by-night startups; they're strategic launches from firms like Entain, Kindred, or Flutter looking to segment markets or refresh their portfolio.
New casinos compete on speed: faster KYC, faster withdrawals, fewer verification hoops. Some adopt instant-play models that let you deposit and start spinning before identity checks complete, settling verification in the background and only gating withdrawals behind ID approval. That reduces time-to-first-bet from minutes to seconds, though it doesn't change the underlying regulatory requirement—you'll still submit documents before cashing out.
Treat new operators cautiously. Check the UKGC register to confirm active licensing, read user reviews on independent forums to gauge withdrawal reliability, and test with small deposits before committing large bankrolls. A shiny app doesn't guarantee competent back-end operations, and newer brands lack the complaint-resolution track record that established operators carry.
Common Issues and Fixes When Using Monzo at Casinos
Declined deposits frustrate players most. If your Monzo card fails at the casino cashier, the gambling block is the first suspect—check your app to confirm it's disabled. If the block is off and deposits still decline, verify that your available balance exceeds the deposit amount plus any pending authorisations from earlier transactions. Monzo holds pending payments for 24–48 hours, and those holds reduce your usable balance even if the transaction hasn't fully settled.
Withdrawal delays beyond the advertised timeline usually stem from incomplete verification. Casinos request ID, proof of address, and sometimes payment method confirmation (a photo of your Monzo card with middle digits masked) before processing your first withdrawal. Upload documents promptly and in the required format—blurry photos or expired documents extend the review cycle.
Duplicate pending charges appear when network errors interrupt the authorisation handshake. The casino's payment processor pings Monzo, Monzo holds the amount, but the transaction times out before the casino receives confirmation. You see a pending charge, the casino sees a failed deposit, and your balance shows the hold until it expires naturally. Contact Monzo support if the hold persists beyond 72 hours.
Currency mismatches cause silent failures. If you attempt to deposit GBP at a euro-denominated casino, the transaction may authorise but post to your account in euros, triggering Monzo's foreign currency markup. Always check the casino's base currency before depositing—most UKGC sites operate in GBP, but some Malta-licensed operators default to euros even for UK players.
Why did my Monzo deposit succeed but my casino balance didn't update?
The payment processor debited your Monzo account but hasn't yet credited the casino's ledger, usually due to a communication delay between the processor and the casino platform. This resolves within minutes in most cases. If your balance doesn't update within an hour, contact casino support with your Monzo transaction reference—they can manually credit your account once they confirm the processor received funds.
Can Monzo reverse a casino deposit?
Only through Mastercard's chargeback process, which requires you to demonstrate that the transaction was unauthorised or that the merchant failed to deliver the service. Gambling losses don't qualify for chargebacks, and attempting to reverse legitimate deposits can result in your Monzo account being restricted or closed. Chargebacks also trigger disputes that may get you blacklisted by the casino and flagged across operator networks.
