Two players on a 6×6 board of four 3×3 regions; the first player is random. Place one marble in an empty hole, then turn any region exactly 90° left or right, never 180°. Rotation may be skipped while a region is empty or has only its center marble. Five or more in a straight horizontal, vertical or diagonal line immediately after placement wins before rotation. Otherwise check after the turn: if only one color has five, that color wins, even if it belongs to the opponent. Both colors making five after rotation, or a full board without five after the complete turn, draws. Single game, no clocks; resigning is allowed.

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