Question: Khet and Quarto, are games of what type?

full_context: Document 1: Ploy (board game): Ploy is an abstract strategy board game for two or four players, played on a 9x9 board with a set of 15 pieces (2-handed) or 9 pieces (4-handed and partnership games) per player. Pieces have various horizontal, vertical or diagonal moves somewhat like chess pieces, except directions of movement are limited; pieces change directions of movement by "rotating". Object of the game is to capture the opponent's "Commander" (analogous to the king in chess), or all of his other pieces.
Document 2: Kharbaga: Kharbaga is a two-player abstract strategy game from Africa. In a way, it is a miniature version of Zamma; however, there are more diagonal lines per square on the board as compared to Zamma. The game is considered part of the Zamma family. The game is also similar to Alquerque and draughts. The board is essentially an Alquerque board with twice the number of diagonal lines or segments allowing for greater freedom of movement. The initial setup is also similar to Alquerque, where every space on the board is filled with each player's pieces except for the middle point of the board. Moreover, each player's pieces are also set up on each player's half of the board. The game specifically resembles draughts in that pieces must move in the forward directions until they are crowned "Mullah" (or "Sultan") which is the equivalent of the King in draughts. The Mullah can move in any direction.
Document 3: ZÈRTZ: ZÈRTZ is the third game in the "GIPF" Project of six abstract strategy games. The game features a shrinking board and an object that promotes sacrifice combinations. Since neither player owns on-board pieces, maintaining the initiative is of fundamental importance.
Document 4: 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.
Document 5: Connect Four: Connect Four (also known as Captain's Mistress, Four Up, Plot Four, Find Four, Fourplay , Four in a Row, Four in a Line and Gravitrips (in Soviet Union)) is a two-player connection game in which the players first choose a color and then take turns dropping colored discs from the top into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the next available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own discs. Connect Four is a solved game. The first player can always win by playing the right moves.
Document 6: Mastermind (board game): Mastermind or Master Mind is a code-breaking game for two players. The modern game with pegs was invented in 1970 by Mordecai Meirowitz, an Israeli postmaster and telecommunications expert. It resembles an earlier pencil and paper game called Bulls and Cows that may date back a century or more.
Document 7: Qwirkle: Qwirkle is a tile-based game for 2 to 4 players, designed by Susan McKinley Ross and published by MindWare. Qwirkle shares some characteristics with the games "Rummikub" and "Scrabble". It is distributed in Canada by game and puzzle company, Outset Media. Qwirkle is considered by MindWare to be its most awarded game of all time. In 2011, Qwirkle won the Spiel des Jahres, widely considered the most prestigious award in the board and card game industry. A sequel, Qwirkle Cubes, was released by Mindware in 2009.
Document 8: Leopard hunt game: Leopard hunt games or simply leopard games are a group of abstract strategy games of Southeast Asian origin, similar in spirit to European fox games, although they are believed to have arisen independently. The games are usually played on a triangular board with three horizontal parallel lines (including the triangle's base) intersecting the other two sides of the triangle and a vertical bisector. Though a number of variants exist, the basic principle of the game sees one player with a single piece (the hunter) and the other playing six or seven pieces (the hunted). Players move pieces in turn along the board's lines. The objective for the hunter is to capture the opponents pieces by "jumping" over them as in checkers while the hunted seeks to corner the hunter so that it has no possible move. Regional variants include
Document 9: Abstract strategy game: An abstract strategy game is a strategy game that does not rely on a "theme". Traditional abstract strategy games will conform to the strictest definition of: a gameboard, card, or tile game in which there is no hidden information, no non-deterministic elements (such as shuffled cards or dice rolls), and (usually) two players or teams taking a finite number of alternating turns.
Document 10: Shannon switching game: The Shannon switching game is an abstract strategy game for two players, invented by American mathematician and electrical engineer Claude Shannon, the "father of information theory" some time before 1951. Two players take turns coloring the edges of an arbitrary graph. One player has the goal of connecting two distinguished vertices by a path of edges of their color. The other player aims to prevent this by using their color instead (or, equivalently, by erasing edges). The game is commonly played on a rectangular grid; this special case of the game was independently invented by American mathematician David Gale in the late 1950s and is known as Gale or Bridg-It.
Document 11: Hex (board game): Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus. Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain. One player must win; there are no draws. The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem. It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash. The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production. Hex can also be played with paper and pencil on hexagonally ruled graph paper.
Document 12: Quoridor: Quoridor is a 2- or 4-player abstract strategy game designed by Mirko Marchesi and published by Gigamic Games. Quoridor received the Mensa Mind Game award in 1997 and the Game Of The Year in the USA, France, Canada and Belgium.
Document 13: Stratego: Stratego is a strategy board game for two players on a board of 10×10 squares. Each player controls 40 pieces representing individual officer ranks in an army. The pieces have Napoleonic insignia. The objective of the game is to find and capture the opponent's "Flag", or to capture so many enemy pieces that the opponent cannot make any further moves. "Stratego" has simple enough rules for young children to play, but a depth of strategy that is also appealing to adults. The game is a slightly modified copy of an early 20th century French game named "L'Attaque". It has been in production in Europe since World War II and the United States since 1961. There are now 2- and 4-handed versions, versions with 10, 30 or 40 pieces per player, and boards with smaller sizes (number of spaces). There are also variant pieces and different rulesets.
Document 14: Pylos (board game): Pylos is a board game invented by David G. Royffe and published by Gigamic. Two players are given 15 marbles each. They take turns to make a pyramid in a 4 by 4 square grid (note that 15 × 2 = 4 × 4 + 3 × 3 + 2 × 2 + 1). Simple rules allow them to save their marbles — if possible, instead of playing a new marble, a player may rise one of his already played marbles to a higher position, and if any move forms a line or 2×2 square of marbles the player's colour, the player may (and indeed must) remove one or two of his marbles from the board. The winner is the player who completes the pyramid.
Document 15: Quarto (board game): Quarto is a board game for two players invented by Swiss mathematician Blaise Müller in 1991. It is published and copyrighted by Gigamic.
