full_context: Document 1: List of word board games: Word board games are those games played on a board as players of the game attempt to construct words that use a scoring system. The player with the highest score wins the game. Many if not most board games are also available as software programs and online. Online word board games can be organized so that the player is playing against other people or the game can be played against an automated program acting as an artificial intelligence. Players of some word board games organize themselves into associations, clubs, and tournaments.
Document 2: Scattergories: Scattergories is a creative-thinking category-based party game originally published by Parker Brothers in 1988. Parker Brothers was purchased by Hasbro a few years later, and they published the game internationally under their Milton Bradley brand. The objective of the 2-to-6-player game is to score points by uniquely naming objects within a set of categories, given an initial letter, within a time limit. The game is based on a traditional game known as Tutti Frutti, Jeu du Baccalauréat, Stadt Land Fluss, and many other names.
Document 3: Words with Friends: Words with Friends is a multi-player word game developed by Newtoy. Players take turns building words crossword puzzle style in a manner similar to the classic board game "Scrabble". The rules of the two games are similar, but "Words with Friends" is not officially associated with the "Scrabble" brand. Up to 30 games can be played simultaneously using push notifications to alert players when it is their turn. Players may look up friends either by username or through Facebook, or be randomly assigned an opponent through "Smart Match". Players can also find potential opponents using Community Match.
Document 4: Ghettopoly: Ghettopoly is a parody of "Monopoly" released in 2003. Invented by David Chang, it uses "Monopoly"-like mechanics in the atmosphere of a caricaturized United States ghetto.
Document 5: Totopoly: Totopoly is a commercial board game, based on the events leading up to, and during, a horse race. Originally made in 1938 by Waddingtons, the game is based on a double-sided board, with each side representing a different half of the game.
Document 6: Poleconomy: Poleconomy is a board game invented by New Zealander Bruce E. Hatherley and first published in 1980. It is similar to "Monopoly" but the board is divided into companies rather than properties. Players compete to acquire properties and investments through stylized economic and political activity. The playing time is set by agreement from all players, e.g. 2 hours, and the winner is determined by the monetary sum of all player cash, companies, insurance or other assets. The game can also end when there are no more companies, advertisements in the bank or bonds in the treasury. Another objective of the game is "to teach players some of the fundamentals of economics, and the ways in which the economy and the government interact." Different editions were published for several different countries. The name "Poleconomy" is a portmanteau of "politics" and "economy".
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: 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 9: The Mad Magazine Game: The Mad Magazine Game, titled Mad Magazine: The "What-Me Worry?" game on the cover, is a board game produced by Parker Brothers in 1979. Gameplay is similar, but the goals and directions often opposite to, that of "Monopoly"; the object is for players to lose all of their money. Play proceeds to the first player's right and the first player is determined by a left-handed roll for the lowest number. The game includes cards, money, dice, and tokens, and the game board features Alfred E. Neuman and illustrations from "Mad magazine". By design, no conclusive strategy exists for the game, since even if a player is winning, several spaces and cards direct players to exchange money or chairs with others, causing advantages to be lost instantly.
Document 10: Rummikub: Rummikub is a tile-based game for two to four players, combining elements of the card game rummy and mahjong. There are 104 number tiles in the game (valued 1 to 13 in four different colors, two copies of each) and two jokers. Players have 14 or 16 tiles initially and take turns putting down tiles from their racks into sets (groups or runs) of at least three, drawing a tile if they cannot play. In the Sabra version (the most common and popular), the first player to use all their tiles scores a positive score based on the total of the other players' hands, while the losers get negative scores. An important feature of the game is that players can work with the tiles that have already been played.
Document 11: Monopoly Junior: Monopoly Junior is a simplified version of the board game Monopoly, designed for young children. It has a rectangular board that is smaller than the standard game and rather than using street names it is based on a city's amusements (a zoo, a video game arcade, a pizzeria, etc.) to make the game more child-friendly.
Document 12: Scrabble: Scrabble is a word game in which two to four players score points by placing tiles bearing a single letter onto a board divided into a 15×15 grid of squares. The tiles must form words which, in crossword fashion, read left to right in rows or downwards in columns, and be defined in a standard dictionary or lexicon.
Document 13: Squatter (game): Squatter is a board game that was launched at the Royal Melbourne Show in 1962, invented by Robert Crofton Lloyd. With more than 500,000 games sold in Australia alone, it became the most successful board game ever developed in Australia. Superficially, Squatter has the appearance of a "Monopoly"-type game. However, unlike Monopoly, all players remain in the game until the end. Players each start the game with their own sheep station and aim to be the first player to improve and irrigate their pastures and then fully stock their sheep station. Players run their sheep station as a business venture, to earn enough money to pay for the seasonal running expenses and to finance the improvements that are required to win the game. The Squatter game presents players with a mixture of strategy and luck that reflects the many challenges facing any form of livestock raising. These challenges include droughts, floods and bushfires, as well as disease, variable livestock prices, and luck. In 1999, a version became available on PC CD-ROM. However the PC version was not commercially successful and is no longer available.
Document 14: Duplicate Scrabble: Duplicate Scrabble is a variant of the board game Scrabble where all the players are faced with the same board and letters at the same time and must play the highest scoring word they can find. Although duplicate is rarely played at competition level in English, it is the most popular form of the game in French and is also played in other languages, such as Romanian and Dutch. The largest French Scrabble festivals can attract over 2000 people and some individual tournaments can count over 1000 participants per game. Although not popular for competitions in English, the computer game "Scrabble 2005" contains a duplicate version allowing up to 16 players to play on the same board at once. It was also used on the UK TV game show "TV Scrabble" as one of the rounds.
