Mathematical game

A mathematical game is a game whose rules, strategies, and outcomes are defined by clear mathematical parameters. Often, such games have simple rules and match procedures, such as Tic-tac-toe and Dots and Boxes. Generally, mathematical games need not be conceptually intricate to involve deeper computational underpinnings. For example, even though the rules of Mancala are relatively basic, the game can be rigorously analyzed through the lens of combinatorial game theory.

Tic-tac-toe Paper-and-pencil game for two players

Tic-tac-toe, noughts and crosses, or Xs and Os, is a paper-and-pencil game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row is the winner. It is a solved game with a forced draw assuming best play from both players.

3D tic-tac-toe abstract strategy board game, generally for two players

3D tic-tac-toe, also known by the trade name Qubic, is an abstract strategy board game, generally for two players. It is similar in concept to traditional tic-tac-toe but is played in a cubical array of cells, usually 4x4x4. Players take turns placing their markers in blank cells in the array. The first player to achieve four of their own markers in a row wins. The winning row can be horizontal, vertical, or diagonal on a single board as in regular tic-tac-toe, or vertically in a column, or a diagonal line through four boards.

Gold barb

Barbodes semifasciolatus, the Chinese barb, is a species of cyprinid fish native to the Red River basin in southeast Asia where they occur in fresh waters at depths of 5 metres (16 ft) or less. The captive variant popularly known as the gold barb or Schuberti barb is an extremely popular aquarium fish.

In mathematics, the Hales–Jewett theorem is a fundamental combinatorial result of Ramsey theory named after Alfred W. Hales and Robert I. Jewett, concerning the degree to which high-dimensional objects must necessarily exhibit some combinatorial structure; it is impossible for such objects to be "completely random".


Puntius is a genus of small freshwater fish in the family Cyprinidae native to South Asia and Mainland Southeast Asia, as well as Taiwan.

Ticto barb

The ticto barb or twospot barb is a species of subtropical freshwater fish belonging to the family Cyprinidae. It is a native of the upper Mekong, Salwen, Irrawaddy, Meklong and upper Charo Phraya basins in the countries of Nepal, India, Pakistan, Myanmar, Bangladesh, Thailand, and Sri Lanka. It has frequently been confused with the Odessa barb in the aquarium trade, but in that species the male is reddish-orange.

Tic Tac Toe (band)

Tic Tac Toe was an all-female German group formed in 1995, performing pop-rap music. Their first two albums, Tic Tac Toe and Klappe die 2te, were million-selling commercial successes and spawned major hits "Ich find' dich scheiße", "Verpiss' dich" and "Warum?". The band found biggest popularity in German speaking countries, the Netherlands and Eastern Europe. Due to numerous scandals and personal issues between the group members, Tic Tac Toe split in 2000. The band had a successful but short-lived comeback in 2005 with the hit single "Spiegel", but ultimately disbanded in 2007.

Tic-Tac-Toe barb is a common name used for two separate species of barbs:

<i>Pethia stoliczkana</i>

Pethia stoliczkana is a freshwater tropical cyprinid fish native to the upper Mekong, Salwen, Irrawaddy, Meklong and upper Charo Phraya basins in the countries of Nepal, India, Pakistan, Myanmar, Bangladesh, Laos, Thailand, China and Sri Lanka.

Criss Cross Quiz was a quiz programme that combined the game noughts and crosses with general knowledge questions and aired on the ITV network from 1957 to 1967. It was produced by Granada Television.

Zillions of Games commercial general game playing system

Zillions of Games is a commercial general game playing system developed by Jeff Mallett and Mark Lefler in 1998. The game rules are specified with S-expressions, Zillions rule language. It was designed to handle mostly abstract strategy board games or puzzles. After parsing the rules of the game, the system's artificial intelligence can automatically play one or more players. It treats puzzles as solitaire games and its AI can be used to solve them.

Tic Tac is a brand of small, hard candy.


Pethia is a genus of small freshwater fish in the family Cyprinidae native to South Asia, East Asia(only Pethia stoliczkana recorded)and Mainland Southeast Asia. Some species are commonly seen in the aquarium trade. The name Pethia is derived from the Sinhalese "pethia", a generic word used to describe any of several small species of cyprinid fishes. For decades, members of this genus were included in Puntius until a recent revision.

Noughts & Crosses is an alternative name for the game Tic-tac-toe


Notakto is a tic-tac-toe variant, also known as neutral or impartial tic-tac-toe. The game is a combination of the games tic-tac-toe and Nim, played across one or several boards with both of the players playing the same piece. The game ends when all the boards contain a three-in-a-row of Xs, at which point the player to have made the last move loses the game. However, in this game, unlike tic-tac-toe, there will always be a player who wins any game of Notakto.

Wild tic-tac-toe

Wild tic-tac-toe is a game similar to tic-tac-toe. However, in this game players can choose to place either X or O on each move. This game can also be played in its misere form where if a player creates a three-in-a-row of marks, that player loses the game.

Tic-tac-toe variants

Tic-tac-toe is an instance of an m,n,k-game, where two players alternate taking turns on an m×n board until one of them gets k in a row. Harary's generalized tic-tac-toe is an even broader generalization. The game can also be generalized as a nd game. The game can be generalised even further from the above variants by playing on an arbitrary hypergraph where rows are hyperedges and cells are vertices.

Matchbox Educable Noughts and Crosses Engine Analogue computer made of matchboxes

The Matchbox Educable Noughts and Crosses Engine or MENACE was an analogue computer made from 304 matchboxes designed and built by Donald Michie in 1961. It was designed to play human opponents in games of noughts and crosses by returning a move for any given state of play and to refine its strategy through reinforcement learning.
