4D Chess is played on a 4x4x2x2 board. The rules of regular chess apply, subject to the following:
- Each 4x4 board is connected to its neighbors (above or below, to the left or to the right) such that each space in one board is orthogonally adjacent to its counterpart in a neighboring board.
- Two spaces are diagonally adjacent if they are two orthogonal steps away.
- Knight motion is defined as moving two steps in one orthogonal direction followed by one perpendicular step.
- Pawns move one step in the forward direction (north, up, 4-east) and capture diagonally forward (northeast, northwest, up-east, up-west, 4-east-north, 4-east-up), with directions reversed for Black. They promote on the opponent's King row.
- No castling, en passant, or two-step pawn moves, and stalemate is a loss.
In the variant, the King is restricted to orthogonal motion.
As with 3D Chess, 4D Chess is designed to be a translation of regular chess into a higher dimension with minimal rule changes.
