Rules and examples
QuaterniTS follows the official basic rules and the illustrated quick rules. The pictured board governs the starting position. The patent provides supporting background but does not override the illustrated rules.
Movement and outcomes
Section titled “Movement and outcomes”- Pawns — ordinary and advanced movement, directional commitment, captures and promotion.
- Checkmate and assimilation — multiplayer check, frozen kings, mate batches and army transfer.
- Draws and other actions — offers, passes, resignation, time loss and walkovers.
- Unresolved positions — a documented edge that fails closed rather than inventing an outcome.
Board examples
Section titled “Board examples”- Starting position — the 64-piece opening and its source comparison.
- Example match — committed moves from the opening followed by an administrative finish; this is not an opening-to-checkmate demonstration.
