Tic Tac Toe: One on One

Across a 3x3 grid, two people trade marks until one line closes first. Tic Tac Toe: One on One strips the match down to local versus play with no computer rival in the seat. Human opponents share the same screen, pick X or O, and claim empty spaces in alternating order until a horizontal row, a vertical column, or a diagonal line belongs to one side.

How to play?

Before the round begins, choose which symbol each person will use, then place that mark in any vacant square when your move comes up. With only nine cells available, each placement blocks space for the other side or extends your own pattern, and the round ends the moment one symbol connects three in a straight line.
