Say 20

Say 20 is a simple number puzzle that challenges the player to figure out why he always loses.

The Player and Computer take turns counting to 20. Each may say one or two numbers on his turn, and whoever "Says 20" wins the game. The Player can also choose to count to 21 with the same rules.

In Say 20 the Computer goes first; in Say 21 the PLayer goes first. The Player always loses because the game is rigged. The Player's challenge is to figure out how the game is rigged and how it can be won.
