The main mechanic revolves around the Boom Banks respin feature. Landing 6 or more coin symbols triggers the bonus, where all coins lock in place and respins are awarded. Reel symbols consist of cuddly toy-type characters, particularly those that you’ll find in the claw machines found at the fair. Which is exactly why the Claw Scatter symbols trigger the Toybox Pick bonus, where you’ll receive up to 5 grabs at claiming a prize. Bet stakes range from £0.10 to £500.00 per spins, with the maximum win being 25,000x your stake.
