Two players on 8×8, 16 pieces each on their two home ranks; White starts. Move one piece one square straight or diagonally forward into an empty square. Capture only one square diagonally forward, never straight ahead. No backward or sideways moves, jumps or landing on a friendly piece. Reach the opposite home rank with any piece to win; capturing all rivals also wins. No promotion or draws. Dan Troyka's 2000 rules, one game without clocks; resigning is allowed.

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