Not to be confused with the Ravensburger game with the same name (look here: 3 Or More) this one is named as a cross between BINGO and Dominoes. The tiles are square and have a number on all 4 sides. Players draw a tile and place it in their 5X5 tray. All sides must match. The first player to place 5 in a straight line wins. Included in the box are rules for a few other variations.
