31bets Casino promotions explained

Every offer on 31bets Casino comes with a window to activate it, a window to use it, and at least one condition that determines whether the winnings are actually yours to withdraw. This page sets out what each current promotion pays, what it costs in wagering or restrictions, and what tends to void a bonus before a player realises it.
T&Cs apply. 18+. New customers only. Please gamble responsibly (BeGambleAware.org).
Free spins and free bets that void themselves
The fastest way to lose a bonus at 31bets is timing. Three of the operator's promotions – the welcome free spins, the Friday free bet and the Wednesday free spins – all share the same structure: a deposit, then a strict one-hour window to activate the code, and another one-hour window to use what it grants. Miss either window and the offer lapses.
- Casino Welcome – 200 Free Spins: needs a €100 minimum deposit, code BR200, and pays 200 spins at €0.20 each on BGaming's Fruit Million. No wagering attached, and the max cashout is €5,000.
- Friday Free Bet: a weekly offer, live Friday 00:00 UTC to Monday 23:59 UTC, needing the same €100 deposit and code FB50 for a 50 free bet. Wager-free, same €5,000 cashout cap.
- Wednesday Special: runs every Wednesday 00:01 to 23:59 UTC. Code WD100 unlocks 100 spins at €0.25 each on BGaming's Elvis Frog in Vegas, again with no wagering and a €5,000 cap.
None of these three carry a wagering multiplier, which sounds generous, but the one-hour activation clock does the same job a wagering requirement would elsewhere: it filters out anyone who deposits and walks away, then comes back later expecting the offer still to be live.
The 170% crypto welcome bonus, and what clearing it involves
Where the free spins packages are wager-free, 31bets' deposit-match offer is not. The 170% Welcome Casino Bonus up to €1,000 requires a 30 €/$/£ minimum deposit and carries a 45x wagering requirement on both the bonus and the deposit amount combined, applied to casino games. That multiplier is the single most expensive term on this page.
Working the multiplier through
A 45x requirement on the combined bonus-and-deposit total means a player depositing €30 and receiving the matching bonus needs to generate turnover several multiples of €30 before a withdrawal request can be made – wagering is calculated on both amounts together, not the bonus alone. The bonus expires after 30 days maximum, so the clock runs the whole time that turnover is being built up.
Stake caps and excluded games while it's active
While this bonus is active, the maximum stake per spin on a slot game is €5. Betting above that voids the win on the bet in question, wagering requirement or not. Eleven slot titles are excluded from progressing the wagering requirement at all, including Arcade Bomb, Hot 777 Deluxe, Gods of Troy, 1942: Sky Warrior and WBC Ring of Riches – time spent on those games doesn't count toward clearing the bonus, even though the stake is real money.
The Combo Booster for sports bets
Outside the casino offers, 31bets runs a sports promotion rather than a straight deposit match. The Combo Booster pays up to a 50% boost on combination winnings, but only on bets covering four or more events at minimum odds of 1.40 per selection, and only within five pre-selected tournaments – Premier League, Bundesliga, La Liga, Serie A and Ligue 1 among them.
| Selections | Boost |
|---|---|
| 4 | 10% |
| 5 | 15% |
| 6 | 20% |
| 7 | 25% |
| 8 | 30% |
The boost caps at €/$5,000 regardless of how large the winning combination is. Players from Finland aren't eligible for sports-related bonuses at all, which is worth checking before building a combo around this one.
Reading the wagering terms that apply across every promo code
Two general rules sit underneath every code-based promotion at 31bets, and they matter more than the headline figures. A freebet must be placed on an accumulator with at least three selections, each at minimum odds of 1.40, and any winnings from it are capped at €100/$100 for withdrawal. Free spins winnings are also capped at €100/$100, then converted into a bonus balance carrying a further 50x wagering requirement with a 7-day expiry.
Odds below 1.30 don't count as wagered at all on the deposit wagering rule that applies to real-money funds generally – a bet placed below that line simply doesn't move the requirement forward, whichever promotion it sits under.
What voids a bonus at 31bets
Bonus funds only become available for wagering once the player's real deposited funds are used up first. Withdraw the main deposit before meeting the turnover condition on the bonus, and both the bonus and any winnings tied to it are forfeited outright.
The operator also treats bet-timing as grounds for closing an account: deliberately delaying game rounds to manipulate wagering progress, or running up in-game value with the intent of cashing out during real-money play, voids the bonus and can lead to account closure. A second or later promo code bonus can also require a further minimum deposit of €20/$20 before the operator processes any withdrawal from it.
Whether taking a bonus is worth it
The wager-free promotions – the welcome spins, the Friday free bet, the Wednesday spins – carry no turnover cost, so the main risk is simply missing the one-hour clock. The 170% deposit match is a different calculation: a 45x wagering requirement on deposit plus bonus combined, an €5 stake cap while it runs, and eleven excluded slots is a real cost, not a formality, and it won't suit a player who wants to withdraw quickly.
None of these offers are guaranteed to be available to every visitor. Eligibility depends on where you live and on the terms current at the time you claim, so it's worth checking the offer's own terms on our site before depositing against it.
Playing within your own limits
A bonus is an incentive, not a reason to stake more than you'd otherwise choose to. If any of these terms make an offer feel like pressure rather than a perk, our BeGambleAware.org signpost and the GamCare National Gambling Helpline (0808 8020 133, free, 24/7) are there regardless of whether you've claimed anything from us.
