Six-dimensional chess is played as five-dimensional chess with the added ability of the pieces to dimension-jump from any tick in one dimension timeline to another parallel dimension timeline, at the same tick.
- Each dimension-jump creates new parallel dimension timelines from both the tick left and the destination tick.
- The original dimension timeline continues without the dimension-jumped piece.
- The tick to which the piece dimension-jumps starts a new parallel dimension timeline with the same tick number as the tick number as the starting dimension timeline.
- Parallel ticks cannot contain duplicates of the same piece. The piece at the destination dimension-jump is taken out of play.
- The object is to play out each parallel dimension timeline with the win going to the opponent capturing the most kings.
