Square-board connection game with the 2018 update. Optionally move a piece, then place a piece, such that no two pieces of a colour are diagonally adjacent unless they are orthogonally connected by a like-coloured stone.

Inventor: Corey Clark

See BoardGameGeek: Slither.

Larger boards (11×11, 13×13).

A piece may move without the mixed-group restriction (classic).
