Renju World Champions
''Renju'' (Japanese: 連珠) is a professional variant of gomoku. It was named renju by Japanese journalist Ruikou Kuroiwa (黒岩涙香) on December 6, 1899 in a Japanese newspaper ''Yorozu chouhou'' (萬朝報). The name "renju" comes from the Japanese language, and means "connected pearls" in Japanese. The game is played with black and white stones on a 15×15 gridded go board. The rule of renju weakens the advantages for the first player (Black) in gomoku by adding special restrictions for Black. Rules Opening rules Unlike gomoku, renju has a unique sequence of opening moves called an "opening rule". There are several certified opening rules. The list of requirements for new opening rules as approved by the Renju International Federation (RIF) in 2003 was: I. Traditions * The basic renju rules must be kept. * The opening stage must not exceed 5 moves. * All 26 canonical openings must be possible and only 26 canonical openings can be possible. * All present realistic var ...

Abstract Strategy Games
Abstract strategy games admit a number of definitions which distinguish these from strategy games in general, mostly involving no or minimal narrative theme, outcomes determined only by player choice (with no randomness), and perfect information. For example, Go is a pure abstract strategy game since it fulfills all three criteria; chess and related games are nearly so but feature a recognizable theme of ancient warfare; and Stratego is borderline since it is deterministic, loosely based on 19th-century Napoleonic warfare, and features concealed information. Definition Combinatorial games have no randomizers such as dice, no simultaneous movement, nor hidden information. Some games that do have these elements are sometimes classified as abstract strategy games. (Games such as '' Continuo'', Octiles, '' Can't Stop'', and Sequence, could be considered abstract strategy games, despite having a luck or bluffing element.) A smaller category of abstract strategy games manages to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Game Complexity
Combinatorial game theory has several ways of measuring game complexity. This article describes five of them: state-space complexity, game tree size, decision complexity, game-tree complexity, and computational complexity. Measures of game complexity State-space complexity The state-space complexity of a game is the number of legal game positions reachable from the initial position of the game. When this is too hard to calculate, an upper bound can often be computed by also counting (some) illegal positions, meaning positions that can never arise in the course of a game. Game tree size The game tree size is the total number of possible games that can be played: the number of leaf nodes in the game tree rooted at the game's initial position. The game tree is typically vastly larger than the state space because the same positions can occur in many games by making moves in a different order (for example, in a tic-tac-toe game with two X and one O on the board, this position co ...

Go (board Game)
Go is an abstract strategy board game for two players in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia. The playing pieces are called stones. One player uses the white stones and the other, black. The players take turns placing the stones on the vacant intersections (''points'') of a board. Once placed on the board, stones may not be moved, but stones are removed from the board if the stone (or group of stones) is surrounded by opposing stones on all orthogonally adjacent points, in which case the stone or group is ''captured''. The game proceeds until neither player wishes to make another move. When ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connect6
Connect6 (; Pinyin: liùzǐqí; ; ja, 六目並べ; ko, 육목) introduced in 2003 by Professor I-Chen Wu at Department of Computer Science and Information Engineering, National Chiao Tung University in Taiwan, is a two-player strategy game similar to Gomoku. Two players, Black and White, alternately place two stones of their own colour, black and white respectively, on empty intersections of a Go-like board, except that Black (the first player) places one stone only for the first move. The one who gets six or more stones in a row (horizontally, vertically or diagonally) first wins the game. Rules The rules of Connect6 are very simple and similar to the traditional game of Gomoku: * Players and stones: There are two players. Black plays first, and White second. Each player plays with an appropriate color of stones, as in Go and Gomoku. * Game board: Connect6 is played on a square board made up of orthogonal lines, with each intersection capable of holding one stone.

Pente
Pente is an abstract strategy board game for two or more players, created in 1977 by Gary Gabrel. A member of the m,n,k game family, Pente stands out for its custodial capture mechanic, which allows players to "sandwich" pairs of stones and capture them by flanking them on either side. This changes the overall tactical assessments players face when compared to pure placement m,n,k games such as Gomoku. Rules Pente is played on a 19x19 grid of intersections similar to a Go board. Players alternate placing stones of their color on empty intersections, with White always assuming the opening move. The goal of the game is to either align five or more stones of the same color in a row in any vertical, horizontal or diagonal direction or to make five captures. Stones are captured by custodial capture (flanking an adjacent pair of an opponent's stones directly on either side with your own stones). Captures consist of exactly two stones; flanking a single stone or three or more stones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIF Rating List
RIF rating list is an official ranking system maintained by the Renju International Federation (RIF), to indicate the rankings of Renju players all over the world. The rating system was established in General Assembly 1995 of RIF. Games between Renju players in formal tournaments are counted in the calculation of the ranking list, including World Championships, European Championships, National Championships and some other important tournaments. The RIF rating list is usually updated daily. The ratings are maintained by the Qualification Commission of RIF. According to the qualification system of the World Renju Championship, all the players with at least 10 games with established players, and within the top-20 of the RIF rating list, have the tickets to take part in the qualification tournament of the World Renju Championship. The RIF rating list had been based on the Elo rating system before 2021, and was migrated to the whole-history rating system in August 2021. Top player ...

Meijin (renju)
is a Renju title in Japan. The Meijin title tournament, formally called the , is played every year in Japan since 1962. The Meijin-sen tournament is one of the most important Renju tournaments in Japan. History and Rule The first Meijin-sen tournament is organized by the Japanese Renju Federation in 1962. Since then, the tournament is played every year except for 1974. During every year with the Meijin title match, two rounds of qualification tournaments are held in parallel in different regions of Japan. The A-class league is made up of 10 players, which are composed of winners of different qualification tournaments, together with three seeds from the last tournament. A round-robin tournament is held among the A-class league, and the winner of the A-class league becomes the challenger of that year. Then a 5-round match is held between the challenger and current title holder. If the challenger gets at least 3 points from 5 games, he wins the match and gains the Meijin title. Other ...

Gomoku
''Gomoku'', also called ''Five in a Row'', is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board. It is played using a 15×15 board while in the past a 19×19 board was standard. Because pieces are typically not moved or removed from the board, gomoku may also be played as a paper-and-pencil game. The game is known in several countries under different names. Rules Players alternate turns placing a stone of their color on an empty intersection. Black plays first. The winner is the first player to form an unbroken chain of five stones horizontally, vertically, or diagonally. Placing so that a line of more than five stones of the same color is created does not result in a win. These are called overlines. Origin Gomoku has existed in Japan since before the Meiji Restoration (1868). The name "gomoku" is from the Japanese language, in which it is referred to as . ''Go'' means five, ''moku'' is a counter word for pieces a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
