Expansions
Two expansions have been released for the game. The Eye of Horus 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 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.
The most recent expansion, released on May 15, 2008, is called "Tower of Kadesh". 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 may move a piece vertically up to or down from the tower, or may move or rotate the tower itself.
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 are plans to release "Tower of Kadesh 2.0" as well.
