The EUR welcome asks 50x wagering on the bonus money, withdrawal times run from one to seven business days of transfer after a business day of processing, depending on the method, the account limit is 3,000 EUR per week, and support runs in English only.

Casino Kings operates under licence MGA/B2C/231/2012 from the Malta Gaming Authority.

Welcome Offers on the UK and EUR Sites

Casino Kings runs two welcome offers, and each player gets one: the two offers do not combine. On the UK site, a first deposit of at least 20 GBP brings 100 free spins, advertised on Big Bass Bonanza by Pragmatic Play. Free-spin winnings are paid as bonus funds and wagered 10x within 7 days, and conversion is capped at 30 GBP. On the EUR site, a first deposit of at least 20 EUR made through the casino cashier earns 175% up to 175 EUR plus 80 free spins on Big Bass Splash by Pragmatic Play. The bonus money is wagered 50x within 30 days and the free-spin winnings 50x within 7 days, with conversion capped at 3 times the bonus and at 20 EUR for free-spin winnings.

Wagering and Bonus Terms

The real balance is wagered first, and only bets made with bonus funds count towards the requirement. A withdrawal request cancels all active and pending bonuses. Video poker counts 5%; blackjack, baccarat, roulette, poker table games and jackpot games count 10%; games on the excluded list count 0%. A single bet above 25% of the initial deposit is treated as an irregular playing pattern.

Mystery Box and the Two Wheels

The Mystery Box (code MBOX) runs from Monday to Thursday. Once a day, a deposit of 20 EUR or more brings a box to open within 24 hours, holding 25 to 100 free spins at random, with a 0.94% chance of the 100-spin prize, for up to 400 free spins a week. The Weekend Wheel of Spins (code WKND500) runs from Friday to Sunday, once a day, and the Midweek Wheel of Prizes (code WED500) runs on Wednesday, once a week. Each time, a deposit of 20 EUR or more brings one spin of the wheel within 24 hours, worth 5 to 500 free spins at random, with a 1% chance of the 500-spin prize. On all three offers, free-spin winnings are wagered 50x within 7 days and conversion is capped at 20 EUR.

October Bonus Boost and SHADOW25

The October Bonus Boost runs through the end of October 2026 with four codes, each usable up to 3 times. OCT26 gives 25% up to 500 EUR from a 20 EUR deposit, with the bonus wagered 50x within 7 days and conversion capped at 3 times the bonus. FS30 gives 30 free spins on Super Wild Fruits – On Ice from 10 EUR, FS60 gives 60 free spins on Wolf Fang – Ice & Fire from 20 EUR, and FS120 gives 120 free spins on Super Miner – Diamond Frenzy from 50 EUR. Until 29 October 2026, SHADOW25 gives 25 free spins on 3 Shadow Wolves by Spinomenal from a 10 EUR deposit, up to 3 times (75 spins). Spin winnings from these codes are wagered 50x within 7 days and capped at 20 EUR.

Rewards Programme
