Mystery Symbol
The Cash Stacker™ feature also brings with it a progressive Mega Jackpot. With electro swing blaring as you spin (and win!), you'll love this ultra-smooth bank heist jackpot game. Give the game a go and pig out on big wins!
When one or more Mystery Symbols land, a random symbol is selected from the Wild, medium or low win symbols, and all Mystery symbols transform into this symbol. The mystery symbol is the Golden Grimoire™, which is shaped like the infamous mysterious book that inspired the game.
The Free Spins symbol is a postage stamp – during free spins, low win symbols are removed for guaranteed wins! And those big winnings will come in handy when you do eventually book a flight to Hawaii – just don't forget to send a postcard!
