How to play

Overview

Tic-Tac-Toe is a two-player strategy game on a 3×3 grid. Take turns placing your symbol — X or O — and be the first to line up three in a row.

Rules

Players alternate moves. X always goes first. A move must land on an empty cell. The game ends when someone gets three in a row horizontally, vertically, or diagonally, or when all nine cells are filled (a draw).
