About
"Impossible Tic-Tac-Toe" is a free online puzzle game found on Poki. It takes the classic tic-tac-toe concept and adds a challenging twist, making it an enjoyable way to spend time when bored. The objective is to place three of your marks in a row on a 3x3 grid with one additional rule: you can't play where the computer has just played, making it quite the brain teaser.
