Abstract: A game is provided where players create expressions which are evaluated and scored based upon how close they are to the number twenty. Players remove five game tiles (16) from the game bag. The tiles are labeled 1-9 (18) or labeled with an operation (20) (time, minus, plus, over), the tiles (16) are approximately ? in. squares and ¼ in. thick. The first player uses three or more game pieces (16) to form an expression. The second player then builds an expression using tiles he has and tiles (16) already on the board. Game play alternates between the two players for the duration of the game. Game-play ends when: all tiles have been played, either player runs out of tiles (16) or when neither player can play tiles. The player with the lowest score wins.
