Learn the ritual
- Make a quiet move with your own stone on either home board. Slide one or two clear squares in any straight or diagonal direction.
- Make an echo move with another stone on a board of the opposite color, on either side of the thread. Repeat the exact direction and distance.
- The echo can push one rival stone, even off the edge. You cannot jump stones, push your own, or push a pair.
- Remove every rival stone from any one board to win.
Tap a stone, then a glowing destination. The next stage highlights possible echo stones. Keyboard: Tab to a square, arrows to travel the board, Enter or Space to choose. Escape cancels a selection.
House profile from USP 1.0: a player with no complete turn loses. Repetition has no automatic draw. Undo or start a new table at any time. The local opponent uses a simple tactical heuristic.
