This page sets out how promotions work at 31bets, the casino and sportsbook covered across our site at 31bets. We're describing what's on offer and what it costs the player to use it — not encouraging anyone to take it. Whether any of it is available to you depends on where you live and on 31bets' own eligibility rules, which we can't override here.
Knowing what voids a 31bets bonus
Before looking at what 31bets offers, it's worth knowing what cancels it. Withdrawing your main deposit before a bonus's turnover condition is met forfeits the bonus funds and any winnings tied to them. Delaying game rounds to exploit a wagering requirement, or building up in-game value with the intention of cashing out during real-money play, voids the bonus outright and can lead to account closure. Bets placed at odds below 1.30 are not counted towards wagering at all, so an accumulator padded with heavy odds-on legs won't clear anything. Players from Finland are not eligible for sports-related bonuses specifically, and the 170% crypto welcome bonus excludes eleven slot titles from its wagering progression, including Arcade Bomb, Hot 777 Deluxe and Gods of Troy.
Understanding the 31bets welcome offers
31bets runs several welcome-style promotions rather than a single package, and they don't all work the same way. T&Cs apply. 18+. New customers only. Please gamble responsibly (BeGambleAware.org).
- A casino welcome offer credits 200 free spins at €0.20 each on BGaming's Fruit Million, against a €100 minimum deposit, using the code BR200. It carries no wagering requirement, but there's only one hour to activate it after depositing and one hour to use the spins.
- A 170% crypto welcome bonus matches deposits up to €1,000, from a €30 minimum deposit, applied to casino games only. This one does carry a wagering condition — 45x on the bonus and deposit combined — with 30 days to clear it and a €5 maximum stake per spin while it's active.
Both cap what they'll pay out: the free-spins offer sets a €5,000 maximum cashout, matching the cap on the Friday and Wednesday promotions covered below.
Reading the conditions attached to each offer
The wager-free promotions still carry real conditions, and they're tighter than the headline suggests. On the free-spins and free-bet offers, winnings convert into a bonus balance capped at €100 maximum withdrawal, and any freebet must be used on an accumulator with at least three selections, each at minimum odds of 1.40. Free-spin winnings that convert to bonus balance then carry their own 50x wagering requirement with a seven-day expiry from activation — separate from the wager-free spins themselves. If a second or later promo code produces a withdrawal, 31bets can require a minimum €20 deposit before releasing it. And there's a general rule sitting underneath all of this: any deposited funds must be wagered at least once before a withdrawal goes through. Request one before that happens, and 31bets can refund the deposit minus a fee of up to 20%.
Following 31bets' recurring promotions
Alongside the welcome offers, three promotions repeat on a schedule rather than running once. The Friday Free Bet pays a €50 free bet against a €100 deposit, available every Friday from 00:00 UTC through Monday 23:59 UTC, using code FB50 — again with a one-hour window to activate and use it. The Wednesday Special mirrors that shape with 100 free spins at €0.25 each on BGaming's Elvis Frog in Vegas, running Wednesdays 00:01 to 23:59 UTC under code WD100. Both are wager-free and both cap at €5,000. A separate Combo Booster rewards accumulators of four or more selections at minimum odds of 1.40 per pick, across five pre-selected tournaments including the Premier League, Bundesliga and La Liga. The boost scales with selections — 10% at four picks, rising to 30% at eight — up to a maximum bonus of €5,000.
Making sense of a wagering requirement
A wagering multiplier tells you how many times a bonus (and sometimes the deposit alongside it) must be staked before any winnings can be withdrawn — it isn't the same as a maximum cashout figure, which is a separate cap on what a bonus can ever pay out. Take the 170% crypto offer as an example: deposit €200 and the 170% match adds €340, well under the €1,000 ceiling. Wagering applies to both amounts combined, at 45x — so (€200 + €340) × 45 works out to €24,300 in total stakes before a withdrawal is possible, and every stake counts only if it's placed at odds of 1.30 or above. Wagering requirements across the market typically sit somewhere around 30–45x on match bonuses, so 31bets' 45x on this offer sits toward the higher end of what's ordinarily seen, not the lower. From 19 January 2026, UK-licensed operators are required to cap bonus wagering at 10x and to keep casino and sports promotions from being mixed into a single unlock condition — a rule that applies to operators holding that licence rather than to the market generally.
Keeping your play in check
None of this is worth chasing past your own limits. If a promotion's terms start to feel like the reason you're still playing rather than a bonus on top of playing, that's worth noticing. 31bets offers self-exclusion for periods between six months and five years, deposit and loss limits, and a temporary time-out on request through support — all reachable by contacting the team directly. Wider support is available too: the National Gambling Helpline on 0808 8020 133 runs free, 24 hours a day, through GamCare, and BeGambleAware.org offers free, confidential advice regardless of where you play. This site is restricted to players aged 18 and over (18+), and a shared household device is worth checking against parental-control software if a minor also uses it.
