Players decorate and spend time in a terrarium, and play match-3 puzzles to earn currency to use in the terrarium. This currency is used to buy toys, decorations, music, and floors. The game features 3 game modes: Endless, with procedurally generated boards; Story, hand-crafted levels across 5 worlds; Terrarium, where players decorate and spend time with slimes. The intent of the game is to be a second screen, fish tank kind of game, where it exists with the player as a companion, but not draw attention to itself.
