Simple Tic Tac Toe

Simple Tic Tac Toe is the classic paper game on a 3x3 grid. Two players take turns marking a square with X or O, and the first to line up three in a row, across, down or diagonally, wins. If every square fills with no winner, the round is a tie.

Playing is just clicking the square you want. The source says the player with the most wins at the end of a series is the overall winner, so you can keep playing rounds on the same screen and keep score as you go.

It is easy for anyone, which makes it a good first game for younger players or a break between longer matches. For a slightly different version, try Tic Tac Toe 2 Player.

Tips

Try the center square first.
Block your opponent as soon as they have two in a row.
A full grid with no winner is a tie, so look for forks before the last squares.
