KHET VS REVERSI

Khet is a chess-like abstract strategy board game using lasers that was formerly known as Deflexion. Players take turns moving Egyptian-themed pieces around the playing field, firing their low-powered laser diode after each move. Most of the pieces are mirrored on one or more sides, allowing the players to alter the path of the laser through the playing field. When a piece is struck by a laser on a non-mirrored side, it is eliminated from the game. Under its original name, the game was a Mensa Select Award winner. Its name was changed on September 15, 2006. The new game retains the same rules of gameplay, but has a different design, including a new color scheme and a new box design. Under the new name, the game was one of five finalists for the 2007 Toy of the Year award. Professor Michael Larson and two students, Del Segura and Luke Hooper, designed the game as a class project at Tulane University. (Professor Larson is now at the University of Colorado.) The game was introduced to the public in the spring of 2005, and was first brought to prominence at the New York Toy Fair of that year. The game was first shipped in October 2005. The first Deflexion World Championship was held December 10, 2005 under the dome at the Massachusetts Institute of Technology. Registration was free, and the participants competed for cash and other prizes. The winner was an MIT student. Under the new name, Khet, the first Regional Championship took place in April 2006 at the famous Café du Monde in the New Orleans French Quarter. Twenty-four participants competed for a number of prizes. 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. Khet was also featured on a recent episode of the HGTV show "I Want That: Tech Toys". Footage from the New Orleans tournament was included in the broadcast. In 2017 a company called "Thinkfun" acquired the license for the now out of print Khet 2.0 and rebranded the game "Laser Chess". Now with a new, modernized scifi look, it brings the exact same rules and feel of Khet 2.0 back to the table.

Reversi is a strategy board game for two players, played on an 8×8 uncheckered board. It was invented in 1883. Othello, a variant with a change to the board's initial setup, was patented in 1971. There are sixty-four identical game pieces called disks (often spelled "discs"), which are light on one side and dark on the other. Players take turns placing disks on the board with their assigned color facing up. During a play, any disks of the opponent's color that are in a straight line and bounded by the disk just placed and another disk of the current player's color are turned over to the current player's color. The objective of the game is to have the majority of disks turned to display one's color when the last playable empty square is filled. Goro Hasegawa claims that the origin of Reversi/Othello dates back 5,000 years. However, there is solid evidence that a game similar to Reversi/Othello existed since the 19th century. Each of the disks' two sides corresponds to one player; they are referred to here as light and dark after the sides of Othello pieces, but any counters with distinctive faces are suitable. The game may for example be played with a chessboard and Scrabble pieces, with one player letters and the other backs. The historical version of Reversi starts with an empty board, and the first two moves made by each player are in the four central squares of the board. The players place their disks alternately with their colors facing up and no captures are made. A player may choose to not play both pieces on the same diagonal, different from the standard Othello opening. It is also possible to play variants of Reversi and Othello where the second player's second move may or must flip one of the opposite-colored disks (as variants closest to the normal games). For the specific game of Othello, the game begins with four disks placed in a square in the middle of the grid, two facing white-side-up, two dark-side-up, so that the same-colored disks are on a diagonal. Convention has this such that the dark-side-up disks are to the north-east and south-west (from both players' perspectives), though this is only marginally consequential: where sequential openings' memorization is preferred, such players benefit from this. The dark player moves first.
