Vigil
Nothing is captured. A piece is held by being watched.
- Each side starts with six pieces on its back row. Ink moves first.
- Move one piece any distance along a row, column or diagonal. Pieces cannot jump.
- A piece seen along open lines by two enemy pieces is frozen until that changes. Frozen pieces still watch.
- A move may not recreate an earlier position.
- If you have no legal move, you lose.
