SAY 20 is inspired by the classic number game NIM.

This version of NIM uses an algorithm that is superior to the one used in the previous version built by MMM and features an improved user interface.


The Player and Computer take turns counting to 20 - each saying one or two digits on a turn. The player who says "20" wins.

The gameboard displays the Computer's move followed by two choice buttons for the Player. Press the Start button to begin the count. Press one of the Choice buttons to register your count.

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.
