a laser. The board has some squares (right file, left corners) that are restricted to pieces of one side or the other, preventing the creation of impenetrable fortress positions. In the original game, the lasers were built into the gameboard; in the "Khet 2.0" version, the lasers are instead built into two extra Sphinx playing pieces, which can be rotated as a player's turn even though they cannot be moved from their starting positions. Scarab (formerly "Djed") and Pyramid pieces have mirrors (one on the Pyramid, and two on the Scarab) positioned such that when the laser beam strikes a reflective side, it reflects at a 90° angle. Players try to position pieces in a fashion that allows the laser beam to reflect into the opponent's Pharaoh, thus winning the game; however, they must also try to protect their own Pharaoh from being struck by the laser beam at the same time. On each turn, a player either moves a piece one square in any direction, or rotates a piece 90 degrees clockwise or counterclockwise. After moving, the player must fire their own laser, and any piece of either color hit on a non-reflecting side (with the exception of Anubis in Khet 2.0 being hit from the front) is removed from play. The pieces in the game are: Pharaoh (1 of each color) The Pharaoh is the most important piece for each side. If hit with a laser, it is destroyed and its owner loses the game. Similar to a king in chess, the Pharaoh pieces are comparatively weak, and so are often not moved unless under duress. Scarab/Djed (2 of each color) Scarabs (formerly called Djeds) consist primarily of large, dual-sided mirrors. They reflect a laser coming in from any direction, and thus cannot be eliminated from the board. Also, unlike other pieces, Scarabs may move into an adjacent square even if it is already occupied, by switching places with the piece found there (whichever color it may be). Thus, they are the most powerful pieces on the board, but must be used with care, as a move that puts one side of the mirror in a favorable position may expose the player to attack using the opposite side of the same mirror. Pyramid (7 of each color) Pyramids have a single diagonal mirror, and form the primary mechanism for directing the path of the laser. They are vulnerable
