There. Not There.
Disappearing tic tac toe, where your oldest move fades away.
There Not There is tic tac toe with one rule that changes everything: each player keeps only three pieces on the board. When you place another, your oldest move fades away. That creates a continuing strategy game where attacks, blocks and timing keep changing.
Play against the computer, challenge a friend online, find a ranked opponent, share one device with Pass and Play, solve today's Daily Sequence, or test yourself in Survival mode.
Play Online is ranked: you are matched with another player who is also searching, and the result changes your skill rating and your place on the daily, monthly and all-time leaderboards. If nobody is searching after about twenty seconds you are offered a clearly named computer opponent instead, and that game does not affect your rating or standings. Play A Friend opens a private room, which is never ranked.
