The game involves helping Sofi, who walks innocently across the screen, to the end of each level. Instead of controlling her directly, players control a cursor and use objects such as stairs, trampolines and slingshots to get her across platforms and protect her from enemies. Similar to Tetris, these items come randomly, with an icon in the corner showing which object will come next. Players can "hold" one item for use later on.
