How to read the shore
You are Moon (dark pebbles). Sun is a local computer, or the other person in two-player mode. Moon begins. Each move must jump a neighbouring rival into the empty square immediately beyond, removing the jumped pebble.
You may keep jumping with that same pebble in the same direction, or stop after any jump. Choose the landing square to decide how far to go. No diagonal moves, ordinary steps or changes of direction. Your pebble always keeps its colour.
No legal jump? You lose. Captures do not score points; making the final jump is the goal. The row is unbounded, so edge jumps are allowed. These are prepared 1×n Kōnane positions, not the opening-removal phase of the full Hawaiian board game.
Select a pebble, then a glowing empty landing square or a jump button. Keyboard: Tab to the shore, arrow keys to explore, Enter or Space to select. Escape cancels. Undo restores your last turn. Guidance reveals an exact winning move when one exists; study badges distinguish guided wins. Progress stays on this device.
