When 3 or more Scatter symbols appear on the reels the player can choose one of the three features on the pop-up – Ice, Fire or Mystery. The number of free games awarded depends on which feature will be chosen.
The Ice feature allows the player to play 7 free games with sticky Wilds. All Wild symbols are locked in place until the end of the Free Games Round.
The Fire feature allows the player to play 15 free games with stacked Fire symbols, which reveals one of the other symbols except Scatter during Free Games.
When the Mystery feature is chosen, the player will be awarded a mystery number of free games (5 to 10) with either sticky Wilds or stacked Fire symbols.
