Legacy of the Wild is a Playtech 40-payline online slot that runs on a game engine built with a folding reel instead of a spinning reel. A variety of 20 images are displayed as symbol waveforms, divided into 4 lines, and then divided into 5 columns of tiles. The winning symbol disappears whenever a wave of icons produces at least one paid combination. The new image will then cascade down the grid and fill only the blank areas left by the disappearing symbols; this may result in a new win event. If the series wins five times in a row, the game will enter the free spin bonus round.
