Sabotage puts a thematic pipe-building spin on Leopard, from Abbott's New Card Games.
Each player has a hand of cards and a playing grid of 3x3 cells. In turn, each player draws and places a card on one of the grids. Most cards can only be placed on a designated cell. For example, 'E'/'5' (Sabotage/Leopard) can only be played into a center cell. A few cards (10-K in Leopard) have special abilities (e.g., wild, cover opponent).
Each row, column, and/or diagonal of three like-colored/-suited cards scores points. Players interact by playing cards of the "wrong" suit on their opponents' layouts, while trying to play "good" suits on their own.
