Rules & objective
Lift every seed from an occupied pit. Drop one per following pit to the right, including the store; wrap to the left if seeds remain. Last seed in the store: choose any occupied pit next. Last seed in a previously occupied pit: lift that whole pit and relay. Last seed in a previously empty pit: lose. Never lift the store. Win only with every seed stored.
Controls
Play directly on the cards or board with mouse or touch. Coordinate selectors are optional keyboard aids.
Worked example
A last seed in an occupied ordinary pit relays. An empty ordinary landing fails; landing in the rightmost store ends that sow.
