- Giant-King Chess. Kings take up four squares each, all of which must be attacked to check. (10x10, Cells: 100) By Robert Shimmin.
- Sacrifice chess. Instead of a normal move, you may sacrifice a pawn. (8x8, Cells: 64) By Robert Shimmin.
- Scheherazade. Pieces may combine with other pieces to form combination pieces. (10x10, Cells: 100) By Robert Shimmin.
- Standoff Chess. A threat to capture the opponent's King does not give check if it opens one's own King to immediate recapture. (8x8, Cells: 64) By Robert Shimmin.
