Bonus Features for Sun-Kissed Rewards

Play Sunny Stacks slot online with these special features for more attractive returns:

  • Sunny Free Games

You'll trigger 8, 10, 12, or 14 extra games when you land 3, 4, 5 or 6 scatters. The highest-paying symbol then becomes wild to enhance your chances of attaining winning combinations. Additionally, the Sunny Respin feature activates during free games but starts with an initial multiplier of x1. This multiplier can randomly increase by 1, 2, or 3 with each subsequent respin, up to x50, till the end of the feature. 

  • Sunny Respin

This feature highlights the top symbol to count as four single symbols, except Scatters. Whenever the top symbol forms part of a winning cluster, it triggers a response where all involved symbols lock in place. Symbols lock again if the game upgrades the winning cluster, including the top icon. The reels then respin. This process continues until no further upgrades unfold in the winning cluster or until the reels are filled with locked symbols. If three or more scatters land during the Sunny Respin, they remain locked until the feature ends. No additional scatters can appear during the respin.

  • Gamble 

Before you start your free games, you have two gamble feature prize options. You either increase the number of extra rounds up to 25 and the initial win multiplier up to x25 or collect the awarded additional games and initial multiplier. You don't want to land on a red section as it could forfeit your chance at the extra free games. However, this outcome will still retain the initial trigger prize. The multiplier resets to the collected value at the end of the respin.
