31Bets Bonuses

31Bets Free Bets and Promo Codes

Bonuses at 31Bets are quite appealing, especially if you’re focused on sports betting. The platform places clear emphasis on rewarding sports bettors with a broader selection of promotions compared to those available for casino players. Upon signing up, you’ll notice several offers tied specifically to sports, such as a traditional welcome bonus tailored for standard sports, along with a separate welcome bonus – eSports + Virtual Sports, which give you a bit of flexibility if you have some specific betting preferences.

Moving on, free bets are a regular feature on the site, alongside a Bet Builder bonus for custom bets from a single match. Sport cashback offers are also available, tied to specific tournaments, returning a percentage of net losses if you are unlucky. In comparison, the casino section has fewer promotions, especially reloads, so regular players mainly interested in slot games might find the selection lacking. Let’s see some more details.

Sports Welcome Bonus – 100% up to €1000

The 31Bets 100% Sports Welcome Bonus gives new players up to €1000 on their first deposit. A minimum of €30 is required, and the offer can be used only once. The bonus must be activated manually after depositing and before your first bet. It is limited to sports markets and cannot be combined with other promotions.

The wagering requirement is 15 times the combined value of your deposit and bonus. Qualifying bets must include at least two selections with minimum odds of 1.40, and you have 30 days to complete the turnover. Only selected bet types count, and markets such as Bet Builder, Baseball, Tennis, Handicap, and Draw No Bet are excluded. Early withdrawals remove both the bonus and any winnings. The terms are designed for active bettors who place consistent volume rather than those seeking a quick cashout.

eSport + Virtual Welcome Bonus – 100% up to €500

31Bets offers a separate welcome bonus for Virtual Sports and eSports, giving a 100% match on your first deposit up to €500. The minimum deposit required is €30, and, as with the main sportsbook bonus, manual activation is required before placing any bets. This is not a crossover promotion, since the bonus is restricted to Virtual Sports and eSports markets and does not apply to traditional sports. The separation is intentional, aimed at punters who focus on digital or simulated competitions.

The terms closely follow the structure of the main sportsbook offer. You must roll over both the deposit and bonus 15 times, using bets with at least two selections and minimum odds of 1.40 per leg. The 30-day wagering window also applies. “Similar bets” are excluded, although the TCs do not clearly define the term, which may create uncertainty in interpretation. The exclusion is likely aimed at pattern-based staking across identical markets. Overall, the offer suits virtual and eSports bettors but requires disciplined stake planning and careful attention to which markets qualify.

Champions League Cashback – 50%

For Champions League bettors, 31Bets offers a 50% cashback as a Free Bet on losing tickets. To qualify, you must place a bet of at least €50 with minimum odds of 1.2 and at least two selections. The maximum cashback per day or per ticket is €200. Live bets are eligible, and you can include other sports in the ticket as long as every selection meets the stated conditions.

The Free Bet is credited instantly once the qualifying ticket settles and must be used on a combo of at least three events, each with minimum odds of 1.4. Winnings from the Free Bet are capped at €1000, and tickets placed with bonus funds or Free Bets do not qualify for cashback. Cashed-out or voided bets are also excluded.

Europa League Cashback – 20%

The Europa League cashback offer at 31Bets follows the same structure as the Champions League version but with lower coverage. Bettors receive 20% cashback as a Free Bet on losing tickets, with a minimum stake of €20. The bet must include at least two selections at minimum odds of 1.2 per leg. Cashback is capped at €100 per ticket and €200 per day and is calculated based on settled bets within a calendar day. Live bets qualify, and cross-sport combinations are allowed as long as all selections meet the conditions.

Once a qualifying ticket settles as a loss, the Free Bet is issued instantly. It must be used on a multiple of three or more events, each with minimum odds of 1.4, and winnings from it are capped at €1000. Bets placed with other bonuses or Free Bets do not trigger cashback, and voided or cashed-out selections are excluded.

Combo Booster – 50%

The Combo Booster is designed for accumulator bets on Europe’s top five football leagues. Players can earn up to a 50% bonus on net winnings from successful accumulator bets, depending on the number of qualifying selections. The minimum requirement is four events, each with odds of 1.4 or higher, and the bonus scales up to 50% for 12-leg combos. All selections must come from the Premier League, La Liga, Bundesliga, Serie A, or Ligue 1, which limits market flexibility but matches the promo’s targeted structure.

Only pre-match bets placed with real money qualify. Live bets, bonus funds, and Free Bets are excluded. The boost is forfeited if any leg has odds below 1.4 or if a match is postponed, annulled, or cashed out. The maximum bonus per winning ticket is €5000. The bonus is credited automatically after settlement and is calculated as a percentage of the net winnings.

Free Bets

31Bets issues FreeBets through its loyalty and promotional campaigns, and they come with fixed usage rules. To convert FreeBets into withdrawable winnings, players must place a bet with at least three selections, each with minimum odds of 1.4. The maximum withdrawal from FreeBet winnings is capped at €100, regardless of stake size or total return. These limits define how FreeBets function and outline the maximum cashout potential.

To use a FreeBet, players must claim it from the My Gift section before going to the sportsbook. Once a qualifying betslip is created with three or more events at minimum odds of 1.4, the FreeBet toggle must be activated before confirming the stake. The system will reject the bet if any selection is below 1.4. Withdrawal eligibility may also depend on previous promo code usage, as players who have redeemed multiple offers may be required to have deposited at least €20 before further bonus-related withdrawals are allowed.

Casino Welcome Bonus – 425% up to €2000

After covering a solid lineup of sports betting offers at 31Bets, it’s worth noting that casino players aren’t left out of the equation. The platform rolls out an aggressive 425% Casino Welcome Bonus package, spread across your first three deposits and adding up to €2000 in potential bonus funds. It’s a clear sign that 31Bets is aiming to attract hybrid bettors or those who prefer spinning reels over backing corners. Whether you’re transitioning from the sportsbook or signing up purely for slots, this offer delivers real upfront value. Here's the breakdown:

• First deposit: 150% bonus up to €1000
• Second deposit: 125% bonus up to €500
• Third deposit: 150% bonus up to €500

Each deposit must be at least €30 to qualify, and the bonus must be manually claimed via the Bonus tab – no auto-crediting here. All three bonuses come with a 45x wagering requirement on the total of deposit + bonus, which is substantial, and only casino games count toward it. Players are given 30 days to complete the wagering, and bets over €5 per spin will void bonus progress. There's also a long list of excluded slots that don’t contribute at all, which makes game selection crucial if you plan to meet the turnover efficiently.
