A futuristic city frequented by rodents is the unlikely setting for Clockwork Mice, a simple, 5 reel, 20 payline slot from Realistic Games. The undoubted highlight here is the Free Spins Bonus feature where you can win up to 96 free spins with multipliers on each free spin of up to 12x. Play on all devices from between 20p and £200 per spin.

The design in Clockwork Mice is simple but well done – the reels are set against a futuristic looking mouse city. On those reels you’ll see A to 9 playing cards as well as a shuttle, a casino and a cafe. These 3 higher paying symbols all offer awards of up to 40 times your stake per payline.

Potentially far more rewarding is the Clockwork Mice logo which pays 10, 125 or 250 times your total stake if you land 3, 4 or 5 on 1 of the game’s 20 paylines. The base game action is pretty pedestrian but the action really comes to life when you trigger the Free Spins Bonus feature.

Land 3, 4 or 5 scatters on the same spin and you’ll receive 12, 24 or 48 free spins. These are played on a new set of reels. Look out for the multiplier clock that appears following each winning free spin. Multipliers are applied to that win. The precise number depends on where the hand lands on the clock. For example, if it lands on 6 o’clock the payout gets a 6x boost.

Once a time has been hit, it’s removed from the clock. If you manage to remove all 12 multipliers from the clock, you’ll receive the maximum bonus prize. You can retrigger more free spins to give you up to 96 free spins. Prizes of up to 250 times your stake can be won during the feature.

Clockwork Mice is a very simple game, both in the way it looks and plays. The bonus round has the potential to be an excellent one though thanks to the large number of free spins on offer and the multipliers of up to 12x. We weren’t expecting too much when we fired up Clockwork Mice. These rodents left us pleasantly surprised though. If you like mice, I recommend you try Quickspin’s Pied Piper.
