Game Rules

Sunny Stacks Rules

Sunny stacks is played on a 5×6 grid with top symbol of 2×2 size above the reels 3 and 4. Wins are awarded when clusters of 9 or more adjacent matching symbols land. Symbols must be adjacent horizontally or vertically (not diagonally).

Sunny Respin

The top symbol is any symbol except scatter and is counted as 4 single symbols. If the top symbol is involved in a winning cluster, it will trigger a sunny respin, symbols involved in a winning cluster get locked.

If the winning cluster including the top symbol is upgraded, symbols involved in a winning cluster get locked and the reels respin. The process repeats until there are no more upgrades of the winning cluster including the top symbol or the reels are fully covered by locked symbols. The winning clusters including the top symbol will only pay once sunny respin is complete. If 3 or more scatters land on the sunny respin trigger, they get locked until the feature ends. Scatters can not appear during sunny respin. Winning clusters not connected to the top symbol pay on current spin or respin, do not re-trigger respin and do not get locked.

Sunny Free Games

3, 4, 5 or 6 anywhere on the reels will award 8, 10, 12, 14 free games respectively. During the free games the top symbol will always be wild. Sunny respin is active during free games, except with attached initial multilplier x1. Starting with second respin multiplier can randomly increase by 1, 2 or 3 to a maximum x50. The multiplier will be applied to winning clusters not connected to top symbol every respin. Once sunny respin is complete, the multiplier will be applied to all winning clusters and reset. During sunny free games 3, 4, 5 or 6 anywhere on the reels will award 8, 10, 12, 14 extra free games respectively.

Play It Your Way

Before free games start, the player can gamble to increase number of free games and the initial multiplier, or collect the free games and initial multiplier that were awarded. To increase initial free games or the initial multiplier, the player must spin one of the two respective wheels and land on a green section. If a red section is landed on, the player loses the free games feature but keeps the initial trigger prize. The player can collect after each extra free game or increase in multiplier is won and enter the free games with the increased number of free games and/or increased initial multiplier. The player can gamble for up to a maximum of 25 free games and up to an intial multiplier of x5. If initial multiplier is increased, it will be applied to all winning clusters regardless respin trigger. Rules of increasing multiplier during respins in free games are the same. After respin ends, the multiplier will reset to the collected value. If the player successfully gambles up to 25 extra free games and an intial multiplier of x5, the game will auto collect and the player will be taken to start of the free games feature.
