Bonuses and Free Spins

Pick a Box Bonus: If you’re lucky, you will be able to pick from one of the special prize boxes available in this game. To activate this feature, you need to land 3 bonus symbols on reels 2, 3, and 4 during regular spins. You will enter a seperate screen, where there are 5 boxes. Each of these boxes contains a different number of free spins (1 - 30) as well as an instant prize (10 - 45). You can get either 1 or 2 rewards from these boxes. This feature cannot be retriggered.

Multiplier: The multiplier can appear on any spin, but only one may appear at a time. This multiplier always appears on reel 5 and multiplies winnings by 2x. 

Wild: There is a special wild symbol that can be used to substitute for any symbol in the game - except the bonus symbol. This symbol can only appear on reels 2, 3, 4, or 5. 

Bet sizes, RTP and Variance

The minimum and maximum bets available in this game are 10 and 900 respectively. Thanks to the 1,024 ways to win and the wild symbol, this is a medium variance game that offers a return of 95%.
