Rule of the game
Glue the 2 sheets on light cardboard, cut out the second page along the outside dotted line. Then cut out the 32 triangles (8 to 8 red 16 black) from the first page.
The game is played by two players: one player takes the 8 green triangles and 8 black triangles. The other player takes the 8 red triangles and 8 black triangles. It is a question for each one of reconstituting on the table above a casserole of color (green or red) the black triangles are only used as filling. The winner is the one who finishes first. Everyone remains free to compose their cocotte in the direction they prefer (see the different examples).
