SlotMaster opens with a 100% welcome bonus up to €500 plus 100 free spins on Multifly! 2 for the first deposit, then keeps a weekly cashback on slot losses and a weekly reload running for players who come back. Deposits go in by card, bank payment service, mobile wallet or crypto. Among the game categories, slots sit next to live dealer tables and game shows.
In our grid, the biggest lift comes from Software Providers, a section that counts among the two heaviest, followed by Casino Games and Mobile Casino.
SlotMaster in Pictures

Identity checks are part of holding an account at SlotMaster: the FAQ states that accounts go through KYC verification. The welcome offer can be claimed once per person.

Our Verdict on SlotMaster
SlotMaster is rated Good, with 7.6/10. Software Providers lifts that grade the most at 10.0, and it is one of the two most heavily weighted sections in our grid. Pragmatic Play, Hacksaw Gaming and Relax Gaming are among the studios on offer. Casino Games, at 8.5, and Mobile Casino, at 8.0, also lift it.
The other five sections finish under the overall mark, from 5.6 to 7.5.
The bonus terms favour slots: slot bets count in full towards the welcome playthrough, against 20% for roulette, and the weekly cashback is worked out on slot losses.
Bonuses and Promotions
The SlotMaster welcome bonus matches the first deposit at 100% up to €500 and adds 100 free spins on Multifly! 2. That deposit has to reach €20, and the offer stays open for 7 days after registration. Real money is played first, and the bonus balance comes into use after it.

The playthrough is 40x the bonus amount, and only bets placed with bonus funds count towards it; it has to be completed within 7 days of activation. While the welcome is active, every round is capped at €5, cash bets included. The free spins are switched on inside the game from the Bonuses area of the account, and their winnings must be wagered within 5 days; the multiplier comes from the general bonus terms, which set 20x. The same general terms cap winnings from a deposit bonus at €2,500. Slots count 100% towards the playthrough, game shows, crash and scratch games 50%, roulette 20%, other games 10% and dice games 0%.
Each Monday, SlotMaster returns 10% of the previous UTC week’s net losses on slots as cashback. It applies to all active accounts, combines with other offers and is claimed from the bonus widget, where it stays valid for 6 days. The minimum payout is €1 and the amount is uncapped. Wagering on the cashback is 1x, and losses are counted on real-money bets only.
The Tuesday Reload is open once a week, from 00:00 to 23:59 UTC that day, and is activated in the cashier. It matches 50% of the deposit up to €100, a deposit of €200 brings the full bonus, and the minimum is €20. The bonus is wagered 35x, again with bonus-funded bets only, and the playthrough must be finished within 72 hours, after which any bonus money left over is forfeited. The €5 cap per round applies, and real money is used before the bonus.
Spooky Seven, a Halloween promotion dated from 26 October to 1 November 2026, gives free spins on the game of the day in return for a deposit of €20 that day: 50 spins on each of the first four days and 100 on each of the last three, up to 500 free spins over the week. The spins have to be used on the day they are credited, and the promotions page lists their winnings at 0x wagering.
