We all play slots for the bonus rounds and these are the most thrilling and entertaining aspects of UK slot games. Bonuses are also the best chance that punters have of landing big wins and recovering any losses that may have occurred during the base game. Bonus rounds come in many forms, some are simple and some complex. The best bonus games and rounds tend to be the ones that keep things straightforward and easy for players to understand. The beauty of triggering bonus rounds is that you give your cash balance a rest and allow it to grow, there is also the possibility of retriggering the bonus round over and over again. Here are a few slots with the best extra games and bonus rounds.

Thunderstruck II
Thunderstruck II is a 5 reels slot that boasts 243 ways to win. It is based on Norse mythology and can be played at low and high stakes. The Thunderstruck II symbol acts as a wild and substitutes for all symbols apart from Thor’s Hammer, which acts as the scatter and landing three or more activates the bonus round. This gains you access to the Great Hall of Spins and the more times you hit a bonus, the more free spins packages you activate. Thunderstruck II is enjoyable to play with great free spin bonuses thrown in for good measure. It also benefits from the random Wild Storm feature that turns complete reels into wilds.

Immortal Romance
Immortal Romance is one of the most famous of all the Microgaming slots. It’s an eerie vampire based game with great graphics and creepy production design. It also boasts a great soundtrack. The Lion symbol acts as the Scatter here and three or more Lion Doorknocker symbols allow you to enter a 4 level free spins bonus round. Each bonus round is headed by one of the main characters from the slot. Amber provides 10 free spins with all wins multiplied by 5x. Troy offers 15 free spins with an added Vampire Bats Feature. These bats randomly appear on the reels and turn symbols into multipliers.

Michael will give you 20 free spins with a Rolling Reels Feature and Sarah provides 25 free spins with a Wild Vine Feature.
