3S Tic-Tac-Toe Arcade Game

Take a familiar three-in-a-row challenge anywhere. Play a computer opponent at three difficulty levels or challenge a friend on the same device. Computer and friend modes keep separate saved matches, so a solo game can wait while you play someone beside you. Return later to resume your computer match. Designed for iPhone and iPad, with layouts that make use of the space available. No app account, advertising or subscription is required.
