Starting a game records your moves under your name. Sign in to play

The clock starts once the first move is made; the solver plays itself untimed.

How to play

Red joins the bottom and top edges, Blue the left and right. Take turns placing a stone on any empty cell; stones never move or leave. The first chain joining your two edges wins, and someone always does. Blue's first move may instead be a swap: Blue takes Red's opening stone and Red moves again.

Beside chess

Invented by Piet Hein and John Nash, who proved the first player wins with perfect play: a pure strategy game, like chess, with no draws at all.

Moves are written as the cells they touch: d4, e2e4, c3e5g7, or swap on Blue's first move.

Quick pairing

Pick a clock. You meet the closest rating waiting in that pool; the range widens while you wait.
