This game is a two-player card game version of the hit strategy game boop designed by Scott Brady. In the new card game, players need to align three Kitten cards in a row to graduate them to Cats, and then align three Cats in a row to win the game. There are cards in this game that add different mechanical twists to gameplay, such as Super Kittens that move cards that are two spaces away and Super Cats that push over other cards into an open space. There are also wild cards and Scaredy Kittens that move when cards get too close.
