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.
Deck-building game A deck-building game is a card game that uses building a deck as the main focus of the gameplay. It is similar to collectible card games (CCGs) in that each player has their own deck. However, unlike CCGs, the cards are not sold in randomized packs, and the majority of the deck is built "during" the game, instead of before the game. Typically, the cards provide a type of game currency which allows players to buy more cards to add to their decks.
