Cipher - "A New game with Numbers" - "A real contest of wits"

This game uses an acetate scoring area and crayons so that the scoring area can be used repeatedly.

In a two player game one player plays for even numbers and the other player plays for odd numbers. Blocks are turned up and plugged into an evolving equation with numbers of the appropriate odd/even type scored by the appropriate odd/even player.

In a four player game players play two on a team for the odd or even side.
