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.
Khanhoo Khanhoo or Kanhu is a non-partnership Chinese card game of the draw-and-discard structure. It was first recorded during the late Ming dynasty as a multi-trick taking game, a type of game that may be as old as "T'ienkiu" ("Heaven and Nines"), revised in its rules and published in an authorized edition by Emperor Kao Tsung in 1130 AD for the information of his subjects. Meaning "watch the pot", it is very possibly the ancestor of all rummy games.
