RTP – 96.42%
The slot has one of the first Cluster pays features you can find, any symbol is a part of a cluster if it is horizontally or vertically adjacent to the same symbol on a winline. If you land 9 or more of the same symbols in a cluster you will be awarded a win.
The Question Mark Crate is the wild symbol and it transforms into the symbol next to it which creates the highest possible winning combination in any cluster. This symbol can appear anywhere on the reels, but it cannot substitute for the Free Spin symbol.
Sticky Win Respin
A cluster win will randomly activate the Sticky Win Re-Spin feature. During this feature, the winning symbols are held and all other symbols will re-spin. During Sticky Win Re-Spin feature, if the winning cluster increases, the symbols increasing the size will stick, and remaining symbols will re-spin again.
Free Spins symbol is a letter stamp, and if you land 3 or more of these anywhere on the reels, either fully or partially, it will activate Free Spins feature. The feature can be re-triggered. The number of spins depends on the number of symbols. During base game you can win between 9 and 12 spins. When re-triggering you can win between 1 and 4 spins.
During Free Spins you will have a Symbol Drop mechanic where low win symbols are removed which increases the chance for wining more during remaining spins. If there is no win during Free Spins you will be getting an extra spin until a win occurs.
