1Win Bonus Offers 2025: Tested Rewards, Free Bets & Spins

When I tested the 1Win bonuses this month, I was genuinely impressed by the variety. If you’re betting on sports, spinning slots, or playing Aviatrix, there’s something designed to keep you playing longer, and potentially winning more.

The bonuses aren’t just flashy headlines either. I actually tried the sportsbook and casino offers to see how easy they are to claim, and more importantly, how fair the wagering terms feel. Some are instant-grab deals (like the free bets and cashback), while others take a little grinding, but the rewards are worth it if you pick the right ones.

If you’re new to 1win, or even if you’ve been around a while but haven’t explored all the bonus options, this review breaks down every type of reward available right now. I’ll show you which ones are truly worth your attention and which ones you can probably skip.

My Opinion on 1Win’s Bonus Strategy

I tested 1win’s bonuses across both sports and casino platforms, and I have to say, I was impressed with the variety and flexibility. On the sports side, I liked the multiple bet bonus because it rewards regular players who enjoy stacking bets without feeling forced into high-risk wagers. The free bets for the League of Legends Championship were a fun surprise. It's clear 1win wants to engage fans of esports with creative, time-limited promos.

For the casino, the welcome free spins and weekend bonuses offer plenty of opportunities to explore slots without overspending. I particularly liked the Halloween tournament and Aviatrix free bets as they add excitement beyond standard gameplay. The cashback and rakeback programs also make me feel like my ongoing play is valued, especially for poker enthusiasts.

That said, there are some caveats. Many bonuses have minimum deposits or country restrictions, and some require careful timing to claim, so casual players could miss out if they aren’t paying attention. Overall, I think 1win balances fun, reward, and fairness well, making it appealing for both newcomers and regular players who want more from their bets.

Responsible play reminder: Bonuses are meant to extend playtime and enhance fun. They don’t guarantee profit. Always check the terms and only wager what you can afford to lose.

1Win Sports Bonuses

When I tested 1win’s sportsbook, I noticed they’re big on rewarding consistency, and not just one-time deposits. The bonuses here are built for bettors who like stacking odds, trying accumulators, or exploring different markets across football, tennis, and even esports. Whether you’re after a simple free bet or a percentage boost on your combos, 1win keeps the action fresh with daily opportunities to grow your winnings.

1Win Multiple Bet Bonus

The 1win Multiple Bet Bonus is designed for bettors who love stacking their odds for bigger wins. The idea is simple; the more selections you add to your bet slip, the higher your potential bonus. It’s 1win’s way of rewarding risk-takers who back multiple outcomes in a single bet. This bonus boosts your total payout percentage based on how many events you include, which can significantly increase your profits on successful accumulator bets.

If you’re building a football combo or mixing sports like basketball and tennis, every extra leg gives you a chance to amplify your winnings.

Technical Details

• Bonus type: Accumulator odds boost
• Minimum selections: 5 events
• Maximum boost: Up to 15% on total winnings
• Eligible markets: Pre-match and live sports
• Minimum odds per selection: 1.3 or higher
• Maximum payout with bonus: Depends on bet size and total odds
• Wagering requirements: None (bonus applies directly to payout)
• Activation: Automatic once your bet meets the conditions
• Mobile compatible: Yes
• Excluded bet types: System bets and cash-out bets do not qualify

My Personal Opinion on This Bonus

This is one of my favorite 1win sports promos. It’s effortless to trigger and doesn’t require any extra steps. You simply bet as you normally would, and the boost kicks in automatically. It’s ideal for bettors who already play combos or accumulators. However, it’s not for cautious players; one wrong pick ruins the entire bet. Still, the upside potential makes it worth trying if you enjoy building multi-legs.

1win Sports Free Bet Bonus

If you’re just getting started or want a little extra boost, the 1Win Sports Free Bet Bonus is a smart and simple way to earn risk-free stakes. The system rewards activity, just place a set number of regular bets, and you’ll automatically earn a free bet. It’s a clean, recurring promo that keeps you betting without overcomplicating things.

This bonus suits casual bettors who place a few wagers every week and want to get more out of their regular play without chasing high stakes.

Technical Details

• Bonus type: Free bet reward
• How to qualify: Place four bets on any sports event in the “Sports” section
• Minimum stake per bet: €6
• Minimum odds per bet: 1.50
• Eligible bet types: Single or multiple
• Reward: €6 free bet credited automatically
• Activation: Once all four bets meet the criteria
• Free bet validity: Limited-time use (check bonus wallet)
• Winnings from free bets: Credited as real balance minus stake
• Excluded bet types: System bets, cancelled bets, and cash-outs

Example

If you receive a €11 free bet and place it at odds of 2.5, a win would return €27. From that, your net winnings are €27 -  €11 = €16 credited to your real balance.

My Personal Opinion on This Bonus

I like how this promo keeps things low-barrier and repeatable. It’s not tied to a first deposit or a one-time event. As long as you’re active, you’ll keep earning free bets. That said, it rewards consistency more than risk-taking, so it’s best for regular, mid-stake bettors rather than high rollers.

1Win LoL Free Bets

This is one of the more creative promos I’ve seen from 1win lately. If you’re into esports, especially League of Legends, the 1win LoL Free Bets promo turns your passion into free stakes during the 2025 World Championship. I tested it myself, and the tiered reward system felt genuinely fair: the more you bet, the bigger your free bet gets. It’s a great way to enjoy the tournament while stacking bonuses on top.

Technical Details

• Event: League of Legends World Championship 2025
• Promotion period:
  • Stage 1: Oct 17–27, 2025
  • Stage 2: Oct 31–Nov 3, 2025
  • Stage 3: Nov 8–15, 2025
• Eligible bet types: Single or multiple
• Minimum single bet odds: 1.5
• Minimum number of selections for multibet: 2
• Minimum odds for multibet: 1.5 per event
• How to join:
  • Click “Participate” on the Sports promo page
  • Place bets on LoL Worlds matches
  • Earn free bets based on total stake

Free Bet Tiers

My Personal Take

I really like this promo for one big reason: it rewards volume without forcing massive stakes. You can scale your bets across matches and still unlock rewards. During testing, I liked that the free bet credits came through reliably after hitting the threshold. The only real drawback? It’s time-sensitive and tied strictly to LoL Worlds, so once the tournament ends, the fun’s over.

1win Casino Bonuses

If you’re more of a casino player, 1win doesn’t disappoint. I was actually surprised by how wide their casino bonus lineup is. It’s not just a welcome offer and done. They’ve got cashback, free spins, seasonal tournaments, and even aviator-specific promos. If you’re a casual spinner or someone chasing leaderboard glory, there’s always something active to boost your play.

Personally, I liked how seamless the bonus activation was. You don’t have to jump through endless hoops or enter codes; most of the offers trigger automatically once you meet the deposit or gameplay requirements.

Let’s start with the biggest one, the 1Win Casino Welcome Bonus, which offers up to 500 free spins across your first four deposits.

1Win Casino Welcome Bonus

The 1win Casino Welcome Bonus is one of the most generous multi-deposit offers I’ve tested this year. Instead of a single match bonus, 1win spreads the rewards across your first four deposits, giving you a total of 500 free spins to use on selected slot games.

It’s a solid introduction to the casino, especially for players who like to stretch their deposits over time. The free spins trigger automatically after each qualifying deposit, so there’s no need for promo codes or bonus requests.

Technical Details

• Bonus type: Free spins (500 total across 4 deposits)
• Availability: New players only
• Currency: RUB
• Deposit 1: 70 free spins for €13+
• Deposit 2: 100 free spins for €14+
• Deposit 3: 150 free spins for €16+
• Deposit 4: 180 free spins for €17+
• Activation: Automatically after each qualifying deposit
• Wagering: Standard slot wagering applies (varies per game)
• Start date: 04/22/2025 (11:00 UTC)
• Region restriction: Available to players from Russia
• Mobile compatible: Yes

My Personal Opinion on This Bonus

I genuinely like this bonus because it’s straightforward, flexible, and offers solid value without overcomplicating things. The 500 free spins feel like a real perk, especially since they’re spread over multiple deposits instead of front-loading everything into one.

What I didn’t like, though, is the region limitation. It’s currently only available to Russian players. If 1win opened this up to more countries, it would easily rank among the best casino welcome bonuses online. Still, if you’re eligible, it’s absolutely worth claiming.

1win Casino Cashback

If there’s one bonus that rewards consistency, it’s the 1win Casino Cashback. This offer gives players up to 30% cashback based on their total slot bets each week. This means the more you play, the more you can recover.

It’s calculated from your real-money losses (not bonus funds), so it’s a genuine safety net for regular slot players. Whether you’re grinding through your favorite reels or just spinning casually, this cashback keeps you in the game longer and softens the blow of a cold streak.

Technical Details

• Bonus type: Weekly cashback on slots
• Maximum cashback: 30%
• Calculation base: Total real-money bets (losses only)
• Eligible games: Slots only
• Wagering: Typically 1x or direct credit (varies)
• Activation time: Automatically credited weekly
• Currency: RUB
• Mobile compatible: Yes
• Excluded bets: Bonus funds not included

My Personal Opinion on This Bonus

I really like this one. Cashback is one of the few bonuses that gives you value after you lose, and 1win’s structure feels genuinely fair. The 30% ceiling is quite high compared to other casinos I’ve tested, where 10–15% is usually the norm.

What’s even better is that it’s automatic. However, I’d have preferred a bit more clarity on whether wagering applies to the cashback itself (some sites bury that detail). Still, as far as recurring rewards go, this one’s a keeper.

1Win Halloween Cash & Treat Tournaments

1win goes all out for Halloween, and this Crash & Treat Tournament proves it. With €25927 in total prizes, this limited-time event turns the casino floor into a full-blown adrenaline fest. Players compete across crash-style games for multipliers and massive leaderboard prizes. Whether you’re chasing total multipliers or aiming for one huge hit, there’s a reward waiting for the top performers.

It’s split into two prize pools of €12963 each, so even if you don’t hit the highest multiplier, consistent play can still get you a slice of the pie. For anyone who enjoys Aviator-style games, this event delivers a mix of excitement, strategy, and spooky-season thrill.

Technical Details

• Total prize pool:  €25927
• Event duration: 13 October 2025 – 2 November 2025
• Minimum bet: €0.39 per round
• Minimum winning multiplier: x2.2
• Eligible games: Selected crash games
• Categories:
  • Highest total multiplier (Top 100 players share €12963)
  • Highest single multiplier (Top 50 players share €12963)
• Opt-in required: Yes (click Participate on the tournament page)
• Mobile compatible: Yes

My Personal Opinion on This Bonus

I love this kind of tournament. It’s not just about luck, but about timing and smart risk-taking. The fact that there are two separate prize pools makes it even fairer; casual players can aim for total multipliers, while high rollers can go for that one monster hit.

The only catch is the short duration. If you blink, you might miss it. Still, as far as themed events go, 1win nailed it with this one. It’s competitive, rewarding, and perfectly timed for players who like that extra bit of thrill.

1Win Free Spins (Weekend Bonus)

Weekends just got a lot brighter at 1win. Every Saturday and Sunday, you can claim 70 free spins simply by making a qualifying deposit. It’s a simple, no-fuss bonus that rewards consistency. It's perfect for players who like to unwind with a few spins over the weekend.

The beauty of this promo is in its flexibility: you get to choose from selected games, so you’re not locked into one slot. Plus, it refreshes every weekend, meaning there’s always another round of spins waiting for you. Whether you’re chasing jackpots or just spinning for fun, this offer keeps the excitement going week after week.

Technical Details

• Bonus type: Free spins
• Availability: Every Saturday and Sunday
• Free spins per day: 70
• Minimum deposit: €13 or USDT 15
• Eligible games: Selected slots (choose in the bonus section)
• Activation: Automatically after deposit
• Availability: Once per day, every weekend
• Promotion start date: 10 May 2025 (00:00 UTC+3)
• Mobile compatible: Yes

My Personal Opinion on This Bonus

I’m a fan of this one. It’s straightforward, easy to trigger, and repeatable. It has all the things I look for in a good casino promo. The ability to claim it twice a weekend (Saturday and Sunday) makes it even better, especially if you’re the type to play casually but often.

If I had to nitpick, I’d say the limited game selection can feel a bit repetitive after a while. But in terms of consistent value, it’s a solid pick that keeps your weekend gaming rewarding without any hassle.

1win Aviatrix Free Bets

If you’re into crash games, 1win’s Aviatrix Free Bets is a great way to start flying. It’s a simple yet rewarding promo where your first flight in the Aviatrix game can earn you 15 free bets, without much strings attached beyond having a small balance and placing your first wager. It’s a nice way to explore the game’s mechanics while getting a few risk-free rounds to boost your confidence.

Technical Details

• Bonus type: Free bets for Aviatrix
• Number of free bets: 15
• Minimum balance required: €5
• Activation condition: Place your first bet in the Aviatrix game
• Availability: For new Aviatrix players
• Game type: Crash game
• Bonus credited: Automatically after first bet
• Mobile compatible: Yes

My Personal Opinion on This Bonus

I really like this one for what it is. It's a simple introduction to Aviatrix with some added fun. It’s not a massive bonus in terms of value, but it’s perfect for testing the waters if you’ve never played before. Plus, crash games have that high-risk, high-reward appeal, so even free rounds feel exciting.

If I had to point out a downside, it’s that you only get the free bets once, so it’s more of a starter perk than a recurring offer. Still, it’s an easy win for beginners who want to get a feel for Aviatrix without dipping into their bankroll too much.

1win Rakeback Bonus

For poker players, 1win’s Rakeback Bonus is one of the most generous ongoing rewards you’ll find anywhere. Instead of focusing on flashy, short-term promotions, this one gives you consistent value week after week. Every Monday, 1win returns up to 50% of the rake you generated while playing cash tables. The higher your VIP level, the more rakeback you receive, starting at 15% and going all the way up to a massive 50% for Diamond-level players.

This system rewards loyalty and volume, making it ideal for regular grinders who put in serious table time. Whether you’re a casual player or someone climbing the poker ladder, getting a portion of your rake back every week helps keep your bankroll healthy.

Technical Details

• Bonus type: Rakeback
• Payout frequency: Weekly (every Monday)
• Rakeback percentage: 15% – 50%, depending on VIP level
• Eligible games: Poker cash tables
• Minimum rake per hand: €0.01
• Maximum rake per hand: €3
• Number of VIP levels: 7 (Player to Diamond)
• Bonus credited: Automatically to your account
• Mobile compatible: Yes

My Personal Opinion on This Bonus

This is easily one of my favorite loyalty features at 1Win. The rakeback structure is transparent and rewarding, and it truly benefits those who play consistently. It’s not a flashy “instant win” type of promo, but it’s perfect for long-term players who understand the value of getting money back over time.

If you’re serious about poker, this one’s a no-brainer. The higher your VIP status, the more you earn back, which creates a solid motivation to keep grinding responsibly.

My Favorite Bonus at 1win

After testing every offer, the 1Win Casino Welcome Bonus stood out as my favourite, and for good reason. Getting up to 500 free spins across your first four deposits is a brilliant way to start your journey. Unlike most casinos that throw everything into one lump offer, 1win spreads the rewards out, keeping you engaged and excited through your early gameplay.

What I really liked is how each deposit unlocks a specific set of free spins, meaning you’re rewarded for consistent activity rather than a single big top-up. The bonus doesn’t just look good on paper, but actually makes your first few sessions more rewarding without demanding unrealistic wagers.

Sure, it’s limited to specific regions, but once you’re eligible, the experience is worth it. The free spins hit on a variety of games, and the activation process is instant. If you love slots, this is hands down the best value bonus 1win currently offers. The gameplay stays fresh, your bankroll stretches further, and there’s that genuine thrill that comes from playing with house-backed spins rather than your own cash.
