Question: Are Jenga and Isola both board games?

full_context: Document 1: Subtract a square: Subtract-a-square (also referred to as take-a-square) is a two-player mathematical game of strategy. It is played by two people with a pile of coins (or other tokens) between them. The players take turns removing coins from the pile, always removing a non-zero square number of coins. The game is usually played as a "normal play" game, which means that the player who removes the last coin wins. It is an impartial game, meaning that the set of moves available from any position does not depend on whose turn it is. Solomon W. Golomb credits the invention of this game to Richard A. Epstein.
Document 2: 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 3: 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 4: Jenga: Jenga is a game of physical skill created by Leslie Scott, and currently marketed by Hasbro. Players take turns removing one block at a time from a tower constructed of 54 blocks. Each block removed is then placed on top of the tower, creating a progressively taller and unstable structure.
Document 5: Icehouse pieces: Icehouse pieces, or Icehouse Pyramids, Treehouse pieces, Treehouse Pyramids and officially Looney Pyramids, are nestable and stackable pyramid-shaped gaming pieces and a game system. The game system was invented by Andrew Looney and John Cooper in 1987, originally for use in the game of Icehouse.
Document 6: Isola (board game): Isola is a two-player abstract strategy board game. It is played on a 7x7 board which is initially filled with squares, except at the starting positions of the pieces. Both players have one piece; it is in the middle position of the row closest to his/her side of the board.
Document 7: 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 8: 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 9: List of domino games: This is a partial list of games played with domino tiles or similar equipment. The most typical domino games are "layout games", i.e. games in which the players add matching tiles from their hand to a layout in the middle of the table. These can be either "blocking games", in which the object is to empty one's hand, or "scoring games", in which the players can score during the game by creating certain configurations. Other games using domino sets are often adaptations of card games. On the other hand, there are also domino-like card games, e.g. Sevens and the once very popular card game Pope Joan.
Document 10: Ex Libris (game): Ex Libris: The Game of First Lines and Last Words is a party game of literary bluff related to fictionary. First published in 1991 by the English board game company Oxford Games Ltd., Ex Libris was devised and compiled by Leslie Scott (the creator of Jenga) and designed by Sara Finch. The game involves having to write fake, but plausible, opening (or closing) sentences of genuine books in an attempt to fool fellow players into believing your words are the authentic first (or last) lines of a given book.
Document 11: Abalone (board game): Abalone is an award-winning two-player abstract strategy board game designed by Michel Lalet and Laurent Lévi in 1987. Players are represented by opposing black and white marbles on a hexagonal board with the objective of pushing six of the opponent's marbles off the edge of the board.
Document 12: Upwords: Upwords (also branded as Scrabble Upwords in the United States and Canada, and Topwords Crucimaster, Betutorony, Palabras Arriba, Stapelwoord in other countries) is a board game invented by Elliot Rudell and originally published by the Milton Bradley Company, now a division of Hasbro. The game remains under license to Hasbro by Rudell Design, LLC. Upwords is similar to "Scrabble", or "Words With Friends", in that players build words using letter tiles on a gridded gameboard. The point of difference is that in Upwords letters can be stacked on top of other letters already on the gameboard to create new words. The higher the stack of letters, the more points are scored. This typically makes words built in later turns of the game more valuable than earlier words, increasing play intensity and adding a level of strategy unique to Upwords. The memorization of two-letter words is considered a useful skill in this game.
Document 13: Villa Paletti: Villa Paletti is a board game of physical skill designed by Bill Payne and published in 2001 by Zoch Verlag. Players compete to build the villa highest using columns from lower floors without collapsing the structure.
Document 14: Twister (game): Twister is a game of physical skill, produced by Milton Bradley Company and Winning Moves, that has been inducted into the American National Toy Hall of Fame. It is played on a large plastic mat that is spread on the floor or ground. The mat has six rows of large colored circles on it with a different color in each row: red, yellow, green, and blue. A spinner is attached to a square board and is used to determine where the player has to put their hand or foot. The spinner is divided into four labeled sections: left foot, right foot, left hand, and right hand. Each of those four sections is divided into the four colors (red, yellow, green, and blue). After spinning, the combination is called (for example: "right hand yellow") and players must move their matching hand or foot to a circle of the correct color.
Document 15: 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.
