The Hawai‘ian traditional capturing game.

First Black and then White remove one stone each (selecting the stone to remove is guided by the interface).Then they alternate (again Black first) capturing an enemy stone by jumping above it orthogonally (no diagonal movement here).

If several jumps are possible (where empty cells and enemy stones alternate) in the same direction (no turns here!), the player may go on as much as they want (and can) after the first (which is mandatory).

The first player who cannot capture (no possible move or no stones) looses.
