Rules & objective
White starts. Move one edge to an empty point; only strong points have diagonal edges. Capture if possible: approach removes the contiguous enemy line ahead of the destination; withdrawal removes the line behind the origin. Choose one if both apply. The same stone may continue capturing, without revisiting any point of this turn or repeating the immediately previous direction. Stopping after a capture is optional. A single noncapturing Paika is allowed only without captures. Remove every opposing stone to win. We use the research edition’s no-move loss and a declared digital draw at the third identical board/side at completed-turn boundaries. No turn cap or Vela honor game.
Controls
Play directly on the cards or board with mouse or touch. Coordinate selectors are optional keyboard aids.
Worked example
A move may offer approach or withdrawal capture; choose one. A capture chain cannot revisit a point already visited in that turn.
