In this game, players are presented with a picture containing different kinds of triangles hidden among other images. The triangles blend with the images so that they are not easily recognized. Each player gets a copy of the picture in a folder. Once they get the go signal, players must find the triangles and mark the outline of each triangle in the image. They must also write the type of each triangle on an answer sheet. The first player to submit the picture showing all the hidden triangles and identifying each triangle correctly wins the game.
This game is played in a large room filled with many objects. Many triangular objects, including objects containing images of triangles, are placed among other objects.
