Sunny Stacks Bonus Features 

Sunny Stacks has a variety of bonus features designed to enhance your gameplay and increase your winning potential. These bonuses include the Sunny Respin, free spins, and gamble feature, each offering unique opportunities for players to maximise their winnings.

Sunny Respin

The Sunny Respin feature is triggered when you land a cluster of certain symbols. During this feature, the triggering symbols lock in place while the remaining symbols respin, giving you a chance to add more matching symbols to the cluster. This can lead to larger clusters and, consequently, bigger payouts. The feature continues as long as new matching symbols are added to the cluster.

How It Works

If additional symbols matching the locked cluster appear, they also become locked and the reels respin again. This can keep going until no new matching symbols land or the grid is filled with the same symbol.

Free Spins

The free spins feature in Sunny Stacks slot is triggered by landing a 3 or more scatter symbols, represented by a pink oyster shell, on the reels in the base game. The number of free spins awarded is determined by the number of scatter symbols that land:

• 3 scatters = 8 free spins


• 4 scatters = 10 free spins


• 5 scatters = 12 free spins


• 6 scatters = 14 free spins

During the free spins, multipliers are active, boosting the value of any winning clusters. The multipliers increase by x1 up to x50 starting from the second respin. Landing additional scatter symbols during the free spins round can retrigger the feature, granting extra spins.

Gamble Feature

Before the free spins round begins, Sunny Stacks offers a gamble feature, allowing you to risk your initial free spins for a chance to increase the number of spins or add higher multipliers. The gamble feature presents you with a wheel with red and green sections. Landing in the green section awards the upgrade, but landing in the red means you lose all your free spins and return to the base game.

Sunny Stacks Review Summary

Sunny Stacks offers a refreshing take on the traditional slot with its beach-themed graphics and innovative cluster pays system. The game is both visually appealing and packed with features that keep players engaged. While the RTP is slightly lower than average, the potential for a 5,000x win makes it an attractive option for many players.

This game is ideal for those who enjoy a mix of steady gameplay and the possibility of landing big wins. The bonus features, especially the Sunny Respin, add a fun twist, making Sunny Stacks a slot worth trying.
