and adding a new strategic element to the game. Eye of Horus beam splitters are available in gold and silver, for those who own the old
Deflexion game, and in red and silver, for those who own the newer Khet game. With the expansion pack, each player receives one beam splitter, which replaces one of their Djeds.
424:
On May 15, 2008 an expansion called "Tower of Kadesh" was released. It adds a 3D element into the game by adding a second level to the game board. The base of the tower has four mirrors that bring the laser up to the top of the tower. In addition to moving a piece horizontally or rotating it, players

beam splitter expansion adds a new piece that is similar to a Djed, but which splits the beam. When a beam strikes the beam splitter, half bounces off at a right angle, as with the other mirrored pieces, while the other half continues on directly through the mirror, thus creating two beams out of one

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

In
January 2011, a new edition of Khet called "Khet 2.0" was released. The gameplay is still the same, but the board and the pieces got a new modern look. The expansions released for Khet 1.0 are not compatible with Khet 2.0, however, "The Eye of Horus 2.0" was released in 2011. There were plans to

Three opening setups are most commonly used: Classic, which is the standard starting configuration, and is the best setup for one's first time playing; Imhotep, which is a variation on the
Classic setup that introduces new defensive possibilities; and Dynasty, which has a fairly even mix of offense
399:
Most new Khet players allow their opponents to "control" the game, and focus on attack or defense depending on the actions of their opponent. However, more experienced players often concentrate on quickly building up a strong defense, and then relentlessly attacking their opponent's pieces, aiming

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
309:
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;
386:
In Khet 2.0, the
Sphinxes hold the lasers. They may not move (each player's is located at their closest right-hand corner) but may be rotated in place so as to fire down the rank instead of the file. A Sphinx is unaffected by laser fire, whether the opponent's or its own reflected back upon
292:
Each player starts the game with 14 playing pieces (12 in
Deflexion) on a 10x8 board, arranged in one of several predefined configurations, and 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

Pharaoh. Some take this strategy even farther, and spend almost the entire game focusing on creating an impenetrable defense, simply waiting for their opponent to make a fatal mistake, or to leave themselves open to allow a quick strike at their Pharaoh. As in

Large pillars with no mirrored sides, these are vulnerable to attack from any direction, and therefore useful mostly as an emergency sacrifice to protect another piece (such as the
Pharaoh). In Khet 1, each player starts the game with four obelisks each; a laser hit always removes an

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.
