Best slot bonuses

The ideal slot bonus will involve a deposit match bonus plus a bunch of free spins on slots. Although these bonuses are getting rarer in the UK, luckily there are still a number of casinos that offer them.

The bonus offered by Unibet casino is one of the best you can claim at the moment. This involves a 200% match on first deposit of £10 or more, which means that you get to play with triple the amount you deposited! What’s more, you also get 10 no deposit free spins simply for registering, plus another massive 190 spins once you make your first deposit.

To get the full Unibet bonus, you need to deposit £100, which will leave you with £300 to play with in total. A decent wagering requirement of 35x applies to this bonus, which is lower than average in this market.

Which slots sites have the best promotions?

Of course, if you intend to keep playing at a casino, you should be looking for regular slot promotions that you can benefit from time and again. This is why you should be after slot sites that run regular promotions which involve bonuses or free spins for existing players.

Spinit casino is one of the best slot sites for regular promotions. Players at this casino can get a reload bonus of 50% up to £100 + 20 Free Spins every Friday or Saturday if they deposit a minimum of £20 on these days.

Some online casinos love to run tournaments on slots to make gaming more fun and competitive. These tournaments provide a great opportunity to win something extra while playing slots, since you can win anything from free spins, bonuses, cash and even luxury gifts and holidays from them.

One of the best slot sites for tournaments is our beloved bgo casino. This casino has a special Tournaments page, where players can view all slot tournaments that will be running. For each tournament, you’ll be able to see the start time and duration, the specific rules and, of course, the prizes that are up for grabs. bgo casino loves to reward players with wager-free spins, as well as cash and awesome 1st prizes like holidays and tickets to special events.

Slot tournaments at Unibet

Unibet casino, which we already mentioned above due to its great welcome bonus, also loves to run slot tournaments, especially on new online slots. Usually, there are huge cash prize pools linked to Unibet tournaments, which are shared among hundreds of players. We like Unibet’s tournaments because they are accessible to players of all budgets.

Usually, all you need to do to participate is just play a specific number of rounds at the minimum bet (which can be as low as 10p per spin). Then, the casino will reward the players with the highest win relative to the stake, so it all comes down to luck and not the amount wagered!
