Simple Tic Tac Toe
A nine-cell grid sets the whole match. In Simple Tic Tac Toe, the classic board stays at 3 by 3, with crosses and zeros placed by two sides in a quick head-to-head round. Three mode choices cover a match against the computer, a local duel for two people, or a watch-only setup that runs computer against computer. The AI opponent sits near the lowest difficulty, making this board game a good place to learn basic tic-tac-toe patterns and see missed chances on the grid.
How to play?
After picking a mode, place a mark in any empty square and build a full row before the other side does. Horizontal lines win, vertical lines win, and a diagonal also ends the round. In computer vs. computer mode, leave the board to the AI pair and watch how their moves create wins, losses, and mistakes.
