About
A take on Tic-Tac-Toe where each move reshapes what can follow. Foresight beats fast clicking.
I came across this family of games in Ben Orlin's Math with Bad Drawings, in a story about mathematicians in Berkeley hooked on an ultimate Tic-Tac-Toe played across nested boards. Forced Move is my version of it.
