Fringilla - tic tac toe app for iPhone and iPad

Fringilla is a game of TIC-TAC-toe on classical and dynamic field. Unlike games on a standard 3x3 box, playing a dynamic field is more complex and exciting. The number of cells depends on the resolution of the screen of the device and can be almost unlimited number of cells.

You can think of a game in which the winner is the first player to built 5 of the same characters on a large enough for this rectangular box. If this field is limited only by the size of the screen.

Play up to 4 symbols on an infinite field uninteresting, for the beginner to quickly build "fork" and wins. Game for n >= 6 also uninteresting because of the "no mans death." There are strategies, not giving the opponent to build the right line ever. However, when n=5, the game becomes much more substantial. This version has a special name - "Gomoku". Initially in Gomoku is played on a Board in the size 19 x 19, later it was reduced to a size 15 x 15 cells.

The main victorious tactics when playing on an infinite field is construction of the intersection ("fork") that do not give the enemy the opportunity to block all the possible ways of constructing five. In order not to lose, it is necessary to interrupt line of the enemy length in three shapes and more.

Practice has shown that in case of equal rules for players who makes the first move, has the advantage of allowing for sufficiently skilled game to win, which was later proved rigorously. To save the interest to the game options were offered for modifications of the rules of the game. So, with the introduction of fouls (illegal moves) for the player who starts the first - it is forbidden to build plug 3 x 3, 4 x 4, as well as to build a "long range" of his pieces - the result is a new game called "Renju [連珠]", with a great variety of game strategies and equal chances players.

Fringilla on dynamic field has a few rounds, each round may end up as a victory of one of the players and the game in a draw. In the game the winner is the one who will win in all rounds, the number of rounds is created automatically and is not known in advance.

To win the game artificial intelligence difficult, but possible! Victory in all rounds in a row is called a "clear victory". Only real professionals can get a clean sweep.

1. Game in a standard game of TIC-TAC-toe on the classical field

3. Three difficulty levels of artificial intelligence
4. The game with another person on a single device
5. Each turn of the game is saved and the game can continue from the same place at any time
