How to play Hiroimono
Hiroimono (Goishi Hiroi — "picking up Go stones") is a sequential path puzzle. Pick up every stone on the board, one at a time, in legal pickup order.
- Start by picking any stone on the board.
- Each next stone must lie on the same row or column as the stone you just picked.
- Your path may not skip any stone that is still on the board — but you may travel over empty squares where stones have already been removed.
- You may go straight or turn 90°. You may not reverse directly back toward the immediately previous stone.
- You win when every stone has been picked up.
- Use H for a hint, Z to undo, R to restart, Space/Enter to check.
★ Three-star ratings reward fast, hint-free solving. Best times persist locally.
