[1] Professor Michael Larson and two students, Del Segura and Luke Hooper, designed the game as a class project at Tulane University.

[6] Under the new name, Khet, the first Regional Championship took place in April 2006 at the Café du Monde in the New Orleans French Quarter.

As a special bonus, the Eye of Horus beam splitter was unveiled at the very end, and used by each player in the championship game.

[7] In 2017 a company called Thinkfun acquired the license for the now out of print Khet 2.0 and rebranded the game "Laser Chess", which kept the same rules, but introduced a sci-fi design.

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 impenetrable fortress positions.

However, more experienced players often concentrate on quickly building up a strong defense, and then relentlessly attacking their opponent's pieces, aiming ultimately to reach the 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.

The wall surrounding the board was removed, which contained the laser emitter, and the Sphinx piece was introduced which cannot move but can be rotated into one of two positions.

A multi-player, cross platform iPhone, iPad and Android app was developed for Khet 2.0 by Schogini Systems of India and Innovention Toys.

[citation needed] The Steam version was created by BlueLine Game Studios and has the first digital implementation of the Beam Splitter expansion.
