- **chess 960** aka **Fisher's random**: Starting position is randomly modified by shuffling the non-pawn rows (with these rules: king must be between rooks, bishops on opposite colors and black/white's positions are mirrored). The rules are the same with a slight modification to castling. This was invented by Bobby Fisher to emphasize pure chess skill as opposed to memorizing the best opening moves, he saw the opening theory as harmful to chess. Chess 960 is nowadays even advocated by some to become the "main" version of chess.
- **[chess boxing](chess_boxing.md)**: Chess combined with box, players switch between the two games, one wins either by checkmate or knockout.
- **different pieces**: Some variants use different pieces, e.g. empress (moves like rook and knight) or amazon (queen/knight).
- **duck chess**: After each move players place a duck on an empty square, the duck blocks the square. The duck cannot be left on the same square, it has to be moved. There are no checks, players win by capturing the king.
- **fog of war**: Makes chess an incomplete-information game by allowing players to only see squares they can immediately move to (this is similarly to some strategy video games).
- **horde chess**: Asymmetric starting position: large number of black pawns vs a white army of traditional pieces. Rules are slightly modified, e.g. black can only be defeated by having all pawns captured (there is no black king).
- **infinite chess**: Infinite chessboard.

- Promotion is always to queen.
- No checks or checkmates, king is just another piece.
- Whoever takes the opponent's king first wins.
- If a player has no available moves, he loses.
- Only a single draw rule: if game doesn't end in 1024 half moves or fewer, it is a draw. I.e. there are no weird draw rules (50 move, repetition, ...). Of course players may still agree on draw anytime.
- Random: optionally random variant of LRS chess can be played. Here we randomly shuffle the white player's back row pieces in the starting position and mirror it for black (no weird conditions on piece positions like in chess 960).
