Play the computer or a friend

The computer plays teal and looks ahead for a winning line or a threat to block. Two-player mode lets you share the same screen, taking turns as amber and teal. Each mode keeps its own round in this browser.

Undo takes back your last full turn against the computer, or one disc in two-player mode. Start a new game after a win or a draw to play again.
