Standard two-player 8×8 Reversi. Black starts. A legal placement brackets one or more consecutive opposing discs; all bracketed lines flip. The server visibly passes your turn when you have no legal move; voluntary passes are not allowed. When neither player can move, the higher actual disc count wins. Equal counts draw. Resigning is allowed.

Rooms expire 24 hours after the last action. Refresh to reconnect; leaving ends the current game.
