Trinome is a very simple move and capture game played on an 11x11 board. Each player has a set of playing pieces with starting positions on his/her side of the board. Triangles can move one space diagonally; squares one space horizontal or vertical and hemispheres two spaces in either direction. If you land on another piece, it is removed from the board. The winner is the first player to place one of each his/her triangles, squares and hemispheres in the red area on the opposite side the board.
