FAQs
-
Can I trust these online slot sites?
Yes. Every slot site on our list holds a UKGC licence. The UKGC monitors its licensees and audits their games to check for fairness and the accuracy of advertised RTP. In addition this, UK licensed casinos are held to high standards when it comes to protecting vulnerable players and player information.
-
Is there a strategy to help me win at slots?
No. Winning at slots comes down entirely to chance and, unlike poker or blackjack, it doesn’t require any skill. This means there’s nothing you can do to increase your chances of landing a winning symbol combination.
-
How much can I win playing online slots?
While some slot games pay out as much as £400,000, the amount you can win depends on how much you bet, and whether you land lucky bonus symbols to boost your winnings. If you’re playing progressive jackpot slots, the amount you win will depend on the size of the jackpot- these can reach well into the millions!
-
Is it possible to find a no wagering no deposit free spins bonus?
No. It’s unlikely that you’ll find no deposit free spins with no wagering requirements at UK slot sites – especially as a welcome bonus. Casinos might offer similar deals as part of a happy hour promotion or loyalty reward program, but you’ll almost always need to have made a deposit in the past.
-
What are the odds of winning online slots?
This depends on the number of reels, the number of symbols on the reels and the number of paylines you bet on. The more simple the slot game, the better your odds for landing a winning combination. For example, if you bet on a 3-reel slot game with seven symbols on each reel, the chances of you landing 3 matching symbols is 1 in 343. However, if you’re playing a 5-reel slot with 10 symbols on each, you’re in with 1 in 100,000 chance of winning.
-
Can I play other casino games at top slot sites?
Yes. While there’s a handful of online casinos that are solely dedicated to slot games, most UK slot sites also offer a selection of other games. While roulette, blackjack and baccarat are the most common selection, some also offer video poker and live dealer casino games.
