Orthogonal connection game where a diagonal of friendly stones can capture adjacent stones that need to be relocated in the same turn. This might result in more relocations starting a chain-reaction.

Inventors: Craig Duncan, João Pedro Neto

See Pinch rules. Default 17×17. Player 1 north–south; player 2 east–west. Orthogonal connection.

Boards 9, 13, 17 (default), 19, 21.

Captured stones flip colour instead of relocating (original).
