About Tic-Tac-Toe
Classic 3 by 3 rounds, best-of-three matches
Each round uses a nine-cell board. The selected starting player makes the first move, then the two sides alternate until one completes a row, column, or diagonal to win the round. Win two rounds to take the match; drawn rounds do not add to either score.
Three CPU levels and local match scoring
Choose Easy, Normal, or Unbeatable CPU difficulty and play as X or O, or switch to two-player mode on the same device. Scores are tracked for the current match only and are not persisted. The game creates no account and does not connect to online multiplayer.
