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.
Patball Patball is a non-contact competitive ball game played in many forms using one's hands or head to hit the ball against a wall – the objective being to get the succeeding player out. The game is popular in school playgrounds during break-time. Patball is played with a tennis ball, or other similar-sized specific patball, and the preferred hand, rather than any form of racquet or bat. The hand is used to "pat" the ball at the wall with the objective of making the ball un-returnable, similar to squash. In some variations of the game the use of the foot is also allowed.
