Grand Heist is a 8×8, cluster-pays video slot with features including cascading wins, free games, multiplier wilds and giant symbols.




96.06 per cent 


In the game, wilds substitute for all symbols and, when forming part of a win, will randomly move to an adjacent vacant position and become sticky for the next cascade. 

Moreover, each wild has a multiplier associated with it, which starts from x1 and will increase by one for every cluster win it participates in. The current multiplier value is applied to the win the symbol contributes to, and if two or more wilds participate in the same cluster win, their multiplier values will be multiplied together. 

Furthermore, landing three or more wilds anywhere on the reels will trigger the free games feature. Here, moving sticky wilds stay on screen for the duration of the feature, which cannot be retriggered. 

Additionally, randomly triggered giant symbols will also appear on the screen during free games. Any positions they cover will be converted to the same type of symbols. 

Lastly, five or more identical symbols in a cluster award a win. All winning clusters are removed from view after paying. This allows more symbols to drop in for increased chances of wins and feature triggers. 


Petra Maria Poola, head of business development and operations at OneTouch, commented: “We’re really excited about this fast paced, high-stakes adventure where players will get the chance to break into a world of underworld activity to get their hands on some potentially enormous wins. 

“It’s time to get cracking in one of our most breath-taking releases of 2021.”
