40 Sharks is Tornado Games' five-by-four aquatic slot with forty fixed paylines. Its normal wild replaces paying symbols but cannot replace the shell scatter. Shells trigger free games, where the shark becomes an additional wild symbol; the feature can also be retriggered. The important distinction is that the shark changes symbol substitution during the bonus. It does not collect cash-labelled fish in the manner of Fishin' Trip's fisherman, and the forty paylines describe winning paths rather than forty independently chosen creatures.
