About There Not There

There Not There is an independent browser game built around a single rule change to tic tac toe.

Classic tic tac toe is solved: two careful players always draw. Limiting each player to three pieces, so the oldest move fades when a fourth is placed, gives the board a constantly changing shape and makes real strategy possible again.

The game is free, runs in the browser, and needs no account. Feedback is welcome through the contact details on this page.
