What 31bets brings to the table for UK players
Slots, live dealer tables, sports betting, virtual sports and a handful of quick-fire mini games sit side by side under one login at 31bets. That range is the first thing worth knowing about the site: this isn't a slots-only operator that bolted on a sportsbook as an afterthought, and it isn't a betting shop with a token casino lobby either. 31bets Casino is built around both, and for players in the UK looking for one account that covers a Friday night on the slots and a Saturday afternoon on the football, that matters.
We've gone through the operator's own terms line by line to put this overview together, and below you'll find what we could actually confirm – the welcome offers, the payment rules, the verification steps – rather than marketing copy repeated back at you. The operator runs under a gaming licence issued by the Government of Anjouan (licence ALSl-202409046-FI2), with the operating company registered in Costa Rica. That's the jurisdiction as published; we're not going to dress it up as something it isn't.

Where 31bets pays out: limits and timing you should plan around
Payments are where a lot of casino reviews go vague, so let's start with the actual numbers. The minimum deposit is €10, and cryptocurrency deposits are exempt from the deposit ceilings that apply to card payments – useful to know if you're depositing larger sums, since 31bets doesn't publish a fixed maximum for card deposits but crypto has no such cap. Withdrawals start at €50.
Withdrawal ceilings are fixed and worth writing down: €7,500 a week and €15,000 a month. Go over the monthly figure and the operator pays the excess in instalments across following months rather than in one lump sum – so a big win doesn't necessarily land in your account all at once. There's also a hard cap on any single bet or spin: 31bets will pay out a maximum of €100,000 per bet or spin, including bonus rounds and free spins, though this doesn't apply to progressive jackpots.
How withdrawal timing actually works
Bank transfers are quoted at up to three business days. Cryptocurrency withdrawals move faster in most cases, which is one reason crypto users tend to favour the platform. One condition that catches people out: any deposited amount has to be wagered at least once before it can be withdrawn. Try to pull it back unwagered and the operator can apply due diligence and refund the deposit minus a fee of up to 20% – so treat that first spin or bet as a formality you need to clear, not an optional step.
Fees that only bite in specific situations
- Accounts left dormant for 12 months incur a €10 monthly administrative charge
- Recovering a mistakenly deposited crypto payment over €5,000 carries a 0.1 BTC retrieval fee
- Depositing or withdrawing via someone else's bank account, wallet or crypto address triggers account termination and a 20% settlement deduction
- Bets placed at odds below 1.30 may not count towards wagering progress
Claiming the 31bets welcome package: what the numbers mean in practice
The headline offer is a 170% welcome bonus up to €1000 on casino play, available from a minimum deposit of just 30 €/£/$. New customers only. 18+. T&Cs apply. Please gamble responsibly (BeGambleAware.org).
Work through what that actually means for a typical deposit. Put in €100 and the 170% match adds €170 in bonus funds, giving you €270 to play with in total. Deposit closer to the €588 mark and the match hits the full €1000 cap – anything you add beyond that point is matched at nothing, since the ceiling is fixed regardless of deposit size. The bonus applies specifically to casino games, and there's a 45x wagering requirement on both the bonus and the deposit amount combined, not the bonus alone. That's the detail most players skim past and then get caught by: wagering 45x on a €270 total means turning over €12,150 before the balance is genuinely yours to withdraw.
Where the 45x wagering actually bites
Say you deposit €200 and receive €340 in bonus funds. Your wagering target is 45 × (€200 + €340) = €24,300 in total stakes. At a modest average bet of €2 per spin, that's roughly 12,150 spins before the bonus converts to withdrawable cash – which is exactly why the operator also caps play at €5 maximum per spin while the bonus is active, and why 11 named slot titles are excluded from contributing to that wagering progress at all, including Arcade Bomb, Hot 777 Deluxe and Gods of Troy. Pick a game outside that exclusion list, or the spins simply don't count.
The bonus itself expires after 30 days maximum, so this isn't something to let sit untouched in your account. Good to know: the deposited funds get wagered before the bonus funds are touched, and if you try to withdraw your original deposit before finishing the turnover, you forfeit the bonus and any winnings tied to it.
The smaller, faster promotions
Alongside the headline package, 31bets runs a rotation of shorter, wager-free promotions that are worth knowing about even if the 170% offer is what draws you in first:
- 200 free spins on BGaming's Fruit Million with a €100 deposit, promo code BR200 – wager-free, with a €5,000 max cashout, but you've only got 1 hour after depositing to activate it and 1 hour to use the spins
- Friday Free Bet – a 50 free bet running every Friday to Monday (00:00 UTC to 23:59 UTC), also wager-free, promo code FB50
- Wednesday Special – 100 free spins on Elvis Frog in Vegas with a €100 deposit, promo code WD100, again wager-free with the same 1-hour activation window
These wager-free offers cap out at €5,000 in max cashout each. Note the short activation windows across all three – an hour to claim, an hour to use – so they suit players who check in regularly rather than those planning to claim and come back days later.
Registering and verifying your account at 31bets
- Fill in the registration form with your email address and other mandatory details
- Choose a username and password for the account
- Make your first deposit (minimum €10, or from 30 €/£/$ if claiming the welcome bonus)
- Wager the deposit at least once before requesting a withdrawal
- Complete identity verification (KYC) ahead of your first payout
Verification only becomes mandatory before your first withdrawal, not at sign-up – you can deposit and play straight away. When it kicks in, 31bets asks for a valid passport, photo driving licence or national ID card, plus proof of address if your ID doesn't already show one, dated within the last six months. Some accounts get asked for extra steps too – video verification or a phone call – and you've got 30 days to submit whatever's requested before the account faces restrictions. The KYC team then reviews uploaded documents within 24 hours.
Withdraw more than €3,000 in a single day, or more than €9,000 across 90 days, and enhanced due diligence kicks in automatically – expect more paperwork if you're playing at that level.
The games running on 31bets
Casino play spans slots, live dealer tables and a set of quick mini games built for short sessions – Aviator, Plinko, Dino and a handful of others sit alongside more traditional Blackjack and Roulette variants. BGaming supplies at least part of the slot catalogue, including the two titles tied to the free spins promotions above, Fruit Million and Elvis Frog in Vegas. The operator doesn't publish a total game count, so we won't invent one – what we can say is that the category spread (casino, live casino, virtual sports, e-sports and mini games) gives a genuinely varied session rather than a single-format lobby.
Some slot providers offer a practice or demo mode on certain titles, though this isn't guaranteed across the whole library – check individual games for a "play for free" option before committing real funds.
Betting on sport through 31bets
The sportsbook sits alongside the casino rather than as a separate product, and one promotion in particular rewards players who bet across several events at once. The Combo Booster adds up to a 50% boost on combination winnings, provided you bet on four or more events at minimum odds of 1.4 per selection. The boost scales with how many selections you add: four selections gets a 10% boost, rising in steps up to 30% at eight selections, capped at a maximum bonus of €5,000.
Five pre-selected tournaments qualify, among them the Premier League, Bundesliga and La Liga – a UK-facing accumulator built around domestic and European football fits neatly into that list. Freebet promotions elsewhere on the site follow their own rule: they need a minimum of three selections at odds of 1.40 or higher, and winnings from a freebet are capped at €100 in withdrawable value.
Using 31bets on your phone
There's no dedicated native app mentioned in the operator's own terms, so the mobile route is through a browser – which in practice means no download, no storage taken up, and the same account whether you're on a laptop or a phone. Casino and sportsbook both run this way, and the registration and verification steps above work identically on mobile.
Getting help from 31bets support
Support runs on email and live chat, 24 hours a day, seven days a week. That round-the-clock cover is genuinely useful if you're chasing a verification query at 2am rather than during office hours. There's no phone line published, so live chat is the faster route for anything urgent.
Our verdict on 31bets
31bets earns its place for players who want casino and sports under one login, and the range genuinely delivers: slots, live tables, a proper sportsbook and a set of quick mini games all sit together, backed by a 170% welcome match up to €1000 plus a run of smaller wager-free promotions. The 45x wagering on deposit plus bonus combined is steep enough that you should go in with a plan rather than expecting an easy cash-out, and the €5 per-spin cap while the bonus is active limits how fast you can play through it.
On the practical side, withdrawal limits are fixed and published (€7,500 weekly, €15,000 monthly), verification only bites before your first payout rather than at sign-up, and support is available around the clock. The licence sits with the Government of Anjouan rather than a UK regulator, which is simply a fact to factor into your own comfort level rather than a red flag in itself. If the game range and the sports betting side appeal, the welcome offer is worth checking out – just read the wagering terms before you deposit large.
Responsible gambling at 31bets
Gambling should stay entertainment, not a routine you feel obliged to keep up. 31bets gives players several ways to stay in control: you can set loss limits directly on your account, ask support to disable deposits for a set period, request a temporary time-out, or self-exclude for anywhere between six months and five years. All of these go through the support channels above rather than a self-service toggle, so reach out directly if you want to use them.
You must be 18+ to hold an account or play. If you're worried about your own gambling, or someone else's, free and confidential support is available around the clock from GamCare (National Gambling Helpline: 0808 8020 133) and BeGambleAware. GamStop offers free self-exclusion across all UK-licensed gambling sites, and blocking software such as Gamban or the free BetBlocker can restrict access at the device level if you share a computer or phone with someone under 18.

What happens if you win more than the maximum win limit at 31bets?
