Havannah (board Game)
Havannah is a two-player abstract strategy board game invented by Christian Freeling. It belongs to the family of games commonly called connection games; its relatives include Hex and TwixT. Havannah has "a sophisticated and varied strategy" and is best played on a base-10 hexagonal board, 10 hex cells to a side. The game was published for a period in Germany by Ravensburger, with a smaller, base-8 board suitable for beginners. It is nowadays only produced by Hexboards. Game rules One player plays as black; the other plays as white. White starts, after which moves alternate. The rules are as follows: * Each player places one stone of their color on the board per turn. * Stones are never moved, captured, or otherwise changed. * A player wins when they complete one of three different structures from unbroken lines, or paths, of connected stones, all of their colour: ** A ''ring'' is a loop around one or more cells (no matter whether the encircled cells are occupied by any player ...

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] |

Sensei's Library
Sensei's Library (commonly referred to as SL among Go-players) is an Internet website and wiki A wiki ( ) is an online hypertext publication collaboratively edited and managed by its own audience, using a web browser. A typical wiki contains multiple pages for the subjects or scope of the project, and could be either open to the pu ..., dedicated to articles about, and discussion of, the game of Go. It was started in September 2000, by the Go players Morten Pahle and Arno Hollosi. Hollosi is also known for designing version 4 of Anders Kierulf's popular SGF file format and for his work with the Austrian Citizen Card project. Sensei's Library is used for a number of purposes, and contains over 20,000 pages on a wide range of topics, such as the culture and history of Go, Go theory, strategy, and community information. It is highly regarded in the Go community. One reviewer noted that as "a collaborative resource written by contributors, Sensei's Library may be the most ...

Generalized Geography
In computational complexity theory, generalized geography is a well-known PSPACE-complete problem. Introduction Geography is a children's game, where players take turns naming cities from anywhere in the world. Each city chosen must begin with the same letter that ended the previous city name. Repetition is not allowed. The game begins with an arbitrary starting city and ends when a player loses because he or she is unable to continue. Graph model To visualize the game, a directed graph can be constructed whose nodes are each cities of the world. An arrow is added from node ''N''1 to node ''N''2 if and only if the city labeling ''N''2 starts with the letter that ending the name of the city labeling node ''N''1. In other words, we draw an arrow from one city to another if the first can lead to the second according to the game rules. Each alternate edge in the directed graph corresponds to each player (for a two player game). The first player unable to extend the path loses. An ill ...

PSPACE-complete
In computational complexity theory, a decision problem is PSPACE-complete if it can be solved using an amount of memory that is polynomial in the input length (polynomial space) and if every other problem that can be solved in polynomial space can be transformed to it in polynomial time. The problems that are PSPACE-complete can be thought of as the hardest problems in PSPACE, the class of decision problems solvable in polynomial space, because a solution to any one such problem could easily be used to solve any other problem in PSPACE. Problems known to be PSPACE-complete include determining properties of regular expressions and context-sensitive grammars, determining the truth of quantified Boolean formulas, step-by-step changes between solutions of combinatorial optimization problems, and many puzzles and games. Theory A problem is defined to be PSPACE-complete if it can be solved using a polynomial amount of memory (it belongs to PSPACE) and every problem in PSPACE can be tr ...

Monte Carlo Tree Search
In computer science, Monte Carlo tree search (MCTS) is a heuristic search algorithm for some kinds of decision processes, most notably those employed in software that plays board games. In that context MCTS is used to solve the game tree. MCTS was combined with neural networks in 2016 and has been used in multiple board games like Chess, Shogi, Checkers, Backgammon, Contract Bridge, Computer Go, Scrabble, and Clobber as well as in turn-based-strategy video games (such as Total War: Rome II's implementation in the high level campaign AI). History Monte Carlo method The Monte Carlo method, which uses random sampling for deterministic problems which are difficult or impossible to solve using other approaches, dates back to the 1940s. In his 1987 PhD thesis, Bruce Abramson combined minimax search with an ''expected-outcome model'' based on random game playouts to the end, instead of the usual static evaluation function. Abramson said the expected-outcome model "is shown to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pie Rule
The pie rule, sometimes referred to as the swap rule, is a rule used to balance abstract strategy games where a first-move advantage has been demonstrated. After the first move is made in a game that uses the pie rule, the second player must select one of two options: # ''Letting the move stand.'' The second player remains the second player and moves immediately. # ''Switching places.'' The second player becomes the first-moving player with the move already done by the opponent, and the opponent plays the first move of their new color. Depending on the game, there may be two ways to implement switching places. # ''Switching colors'' means that the players exchange pieces. The player who made the first move becomes the second player and makes the second move on the board. This is demonstrated in the chess diagrams shown here. # ''Switching the first piece'' can occur in games where the board starts empty and the first move consists of placing one piece. Suppose the colors are whit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ravensburger
Ravensburger AG is a German game and toy company, publishing house and market leader in the European jigsaw puzzle market. History The company was founded by Otto Robert Maier in Ravensburg, a town in Upper Swabia in southern Germany. He began publishing in 1883 with his first author contract. He started publishing instruction folders for craftsmen and architects, which soon acquired him a solid financial basis. His first board game appeared in 1884, named ''Journey Around the World''. At the turn of the 20th century, his product line broadened to include picture books, books, children’s activity books, art instruction manuals, non-fiction books, and reference books as well as children’s games, Happy Families, and activity kits. In 1900, the Ravensburger blue triangle trademark was registered with the Imperial patent office. As of 1912, many board and activity games had an export version that was distributed to Western Europe, the countries of the Danube Monarchy as well ...
