CosmoBet Bonuses

CosmoBet Free Bets and Promo Codes

CosmoBet offers a decent selection of bonuses, as the most appealing offer is clearly the welcome bonus, which gives you a 150% boost on your first deposit. This is noticeably higher than what many other platforms provide, a notable fact.

In addition to the welcome deal, you'll find some interesting sports promotions that cross over into the casino side. For example, placing certain bets on sporting events can earn you free spins on selected slot games. These blended promotions add a bit of variety, especially if you like switching between sports betting and casino play. However, one thing to keep in mind is that there aren't any reload bonuses specifically for sports, which might be a let-down if you're used to regular top-up offers. Let’s see more details, now.

CosmoBet Sport Welcome Bonus – 150% up to €1000

CosmoBet introduces new players to its sports section with a substantial 150% match on the first deposit, offering the chance to claim up to €1,000. To activate this deal, a minimum deposit of €20 is required, and players must manually opt in before placing their first bet, which is something experienced bettors should keep in mind to avoid missing out. The associated terms are geared toward accumulator players, as qualifying wagers must be multi selections with at least three legs, and each leg must be set at minimum odds of 1.30. This structure works well for building multis, but it prevents using the bonus on single bets or tickets focused only on short-priced favourites.

The wagering requirement is 15 times the combined deposit and bonus amount, with a 30 day period to complete the conditions. While the multiplier is standard, the total sum can become large, making a carefully planned betting strategy important. One key distinguishing feature of this offer is the highly flexible maximum bet limit of €1,000 while the bonus is active. This provides an unusual degree of freedom compared to most welcome packages in other betting sites.

Euroleague Insured Points – 1000 free spins

This promotion offers a unique blend of sports betting insurance and a casino reward. If you place a qualifying basketball accumulator on EuroLeague Group Stage matches and the entire ticket loses, CosmoBet provides a safety net by returning 50% of your stake as free spins. Eligibility requires a minimum €20 bet with at least two selections, and each selection must be priced at odds of 1.60 or higher. The offer only activates if the entire bet slip loses, so it works as a genuine consolation for a complete failure.

The reward is delivered as free spins for the 5x Magic slot game, with each spin valued at $0.50, and they are credited within 24 hours after the losing bet has settled. Participants can claim up to 1,000 free spins over the course of the campaign, with a daily limit of 200 spins. This promotion appeals strongly to players who enjoy switching between sports betting and casino games. Since the reward is based on a losing outcome, it softens the impact of a missed ticket while also encouraging engagement with the casino side of the platform.

Rugby’s Elite Clash – €200 free bet

The focus of this promotion is immediate gratitude, offering a reward as soon as a qualifying rugby bet is placed. Wagering at least €20 on European Rugby Champions Cup Group Stage matches with two or more selections at minimum odds of 1.60 each triggers an instant 50% Plinko Bonus. Delivered as a MiniGames Free Bonus, the reward can reach up to $200, scaled according to the qualifying stake. The bonus is applied immediately, meaning no wagering requirements, which is a significant advantage.

CS2 Free Spins Promo – 500 free spins

This Esports focused promotion works as a complete insurance policy against a losing accumulator bet. By placing a qualifying wager of at least €20 on the StarLadder Budapest Major 2025, you are guaranteed a 100% refund of your stake in free spins if the bet loses, up to a maximum of 500 spins. Qualification requires an accumulator with at least two selections, and each selection must have odds of 1.40 or higher. The free spins are valued at $0.05 each and are credited within 24 hours after the losing bet has been settled.

Green Table Glory – €200 free rounds

Targeting snooker enthusiasts, this UK Championship promotion allows players to recover a portion of their loss through casino credits. Placing a qualifying bet of at least €20 on UK Championship matches and having the entire slip lose results in a 30% stake refund in Plinko free rounds. The bet must meet accumulator requirements, with at least two selections, and each selection must be priced at minimum odds of 1.40. If the accumulator bet fails, the free rounds, which can be worth up to $200, are credited within 24 hours.

NBA Insurance – 50% cashback

CosmoBet offers NBA Bet Insurance to give players a second chance when their basketball accumulators don't hit. If a qualifying NBA bet of at least €20 is fully lost, 50% of the stake is returned as a Free Bet, which is restricted to use on the Mini Games Plinko or Keno. Qualification requires a three-leg accumulator minimum, with each selection having odds of 1.30 or higher. The Free Bet is typically credited within 24 hours of settlement, with only fully lost tickets eligible for the return. The promotion enforces a daily cap of $200 in Free Bets and an overall maximum of $500 throughout the campaign.

500% Express Challenge

This is a powerful, multi-layered incentive for betting on elite European football tournaments, including the Champions League, Europa League, and Conference League. By placing express bets with a minimum of four legs, each at odds of at least 1.35, players qualify for a Free Bet bonus even if only one selection loses. The bonus scales aggressively, starting at 50% for a four leg slip and rising to 500% for an eight leg ticket. With a minimum stake of €10 and a maximum Free Bet of €500 per ticket, this structure greatly reduces the frustration of near misses on longer multiples.

In addition to the insurance component, these qualifying express tickets are automatically entered into a €5,000 leaderboard competition. Points are calculated based on the total odds of each ticket and can be earned even from tickets with one losing leg. The leaderboard updates after every matchday, creating real time competition for the top 20 cash prizes, which go up to €1,000.

Make 3 Bets Get the 4th for Free

The Make 3 Bets Get the 4th for Free promotion is a simple, effective loyalty reward for consistent accumulator play. After placing and settling three qualifying bets, you receive a Free Bet worth 15% of their combined value. Each of the three bets must be at least €10, include a minimum of three selections, and have minimum odds of 1.3 per selection. This offers transparent value; for example, three €100 bets would return a €45 Free Bet, with the minimum Free Bet set at €10 and the maximum capped at €100. Crucially, only accumulator bets are counted; single, system, outright, or cashed-out bets are ineligible, and wagers on player-specific markets are also excluded. The Free Bet amount is based on the average stake of the three settled tickets.

Delete The Game

CosmoBet’s “Delete Game” feature provides a flexible, albeit costly, way to manage active accumulator bets. This function allows you to remove a single selection from a running ticket, but doing so incurs a fixed penalty: 10% of your current total stake is deducted with each adjustment. For example, a €100 bet drops to €90 after one removal, and further removals compound the reduction, impacting the final potential return.

This management tool is exclusively for standard accumulator bets, and cannot be used on single or system bets. You are permitted to remove any selection unless its live odds have increased by more than 30% compared to the original locked-in price. After using the remove function, options like cashing out or adding new selections remain available, though the cashout value will be based on the new, reduced stake.

CosmoBet Casino Welcome Package – Up to €2000 + 1000 FS

The Cosmic Welcome Package from CosmoBet stretches across your first four deposits, offering up to 400% in total bonuses and as many as 1,000 free spins. Each deposit provides a 100% match up to €500, along with a free spins allocation that depends on how much you deposit. The minimum deposit to trigger each part of the offer is €20, and you must manually activate the bonus in your profile under the Bonuses section before placing any bets. If you do not activate it beforehand, the reward will not be added, keep this in mind. Depositing €200 or more unlocks the full 250 free spins per deposit. Smaller deposits result in 100 or 50 spins, depending on the amount.

The wagering requirements are strict, with 30 times the combined amount of your deposit and bonus, and only seven days to complete it. All wagering must be done on slots, and several titles are excluded, so checking the eligible games is essential. The maximum stake allowed during wagering is €5, and withdrawing funds before meeting the requirement will result in the forfeiture of both the bonus and any winnings. The free spins have a value of €0.10 each and expire 24 hours after they are credited, so timing is important. Here is how the bonus breaks down clearly:

• 1st Deposit Bonus – 100% up to €500 and 50 to 250 free spins (depends on the deposit size)
• 2nd Deposit Bonus – 100% up to €500 and 50 to 250 free spins
• 3rd Deposit Bonus – 100% up to €500 and 50 to 250 free spins
• 4th Deposit Bonus – 100% up to €500 and 50 to 250 free spins
