Khet and Quarto, are games of what type?
Khet (game) 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.
Trex (card game) Trex, pronounced Tricks or Trix, and also known as Ticks, is a four-player Middle Eastern card game mainly played in the Levant region (Jordan, Syria, Lebanon and Israel). Similar to the European game of Barbu, Trex takes on a cycle style in which there are four cycles with each cycle consisting of five games. Each cycle is called a "kingdom" in reference to the fact that in each cycle one player (the King) determines which contract to play in each of the five games.
