How to play kōnane
One kind of move, no draws, and a game that gets sharper as the board empties. It takes about a minute to learn.
The board
Kōnane is played on a grid, traditionally carved into stone, in a range of sizes. This version uses a 6×7 board. Every square starts covered, alternating black and white.
Opening
Black begins by removing one black stone. It can be any stone except those along the edges, though the corners are allowed. White then removes one of its own stones directly beside that empty square. Play begins with two gaps and Black to move.
Moving
There is only one kind of move: a jump. Move one of your stones over an adjacent opposing stone and land in the empty square directly beyond it. The stone you jumped is removed from the board.
Jumps go up, down, left and right, never diagonally. There are no quiet moves either, so if you cannot jump, you cannot move.
Multiple jumps
After a jump, that same stone may jump again, but only in the direction it was already travelling. It cannot turn a corner mid-turn. You may stop after any jump, and you are never forced to take everything available.
Winning
There is no capturing everything, no reaching the far side, and no draws. When it is your turn and you have no legal jump, you lose. That is the only way the game ends.
What to think about
Stones are not points. Being ahead in captures means nothing if you run out of moves first. What matters is how many jumps remain available to you compared to your opponent, and whether the ones you have can be taken away.
