How to play Pixel Tic-Tac-Toe
Two players take turns placing X and O on the shared three-by-three board. The first player to make a horizontal, vertical, or diagonal line of three wins. If every square fills without a line, the round is a draw.
Start with the center
The center touches four possible lines, so it gives the opening player useful options. More importantly, look for a move that creates two threats at once. This is a fast same-screen game with easy rematches.
