Fringilla is a game tic-tac-toe on a dynamic field. Unlike game on a standard field 3х3, game on a dynamic field is more difficult and fascinating. The quantity of cages depends on the permission of the screen of the device and can practically make not limited quantity of cages.

It is possible to consider game in which the winner the player is considered, the first constructed 5 identical signs on big enough for this purpose a rectangular field. At this field it is limited only to the size of the screen.

Game to 4 identical signs on an infinite field is uninteresting, for the beginner quickly enough builds "plug" and wins. Game at n >= 6 also is uninteresting because of «neutral death». There are the strategy which are not giving to the opponent to construct the necessary line never. However at n=5 game becomes much more substantial. Such variant has the special name - gomoku. Initially in gomoku played a board in the size 19x19, later it has been reduced till the size in 15x15 cages.

Basic victorious tactics at game on an infinite field considers construction of crossings ("plugs") which do not give to the opponent of possibility to block all possible ways of construction of the five. Not to lose, it is necessary to interrupt in due time lines of the opponent in length three figures and more.

Practice has shown, that at equal rules for players the one who does the first course, has the advantage allowing at enough qualified game to win, that subsequently has been proved strictly. For preservation of interest to game various variants of updating of game rules were offered. So, with introduction fouls (the forbidden courses) for the player, beginning - to it it is forbidden to first to build a plug 3x3, 4x4, and also to build "long line" from figures - has turned out new game under the name Renju [連珠], with the big variety of strategy of game and equal odds of players.


Fringilla has some rounds, each round can will end both a victory of one of players and game in a drawn game. Game is won by the one who will win in all rounds, the quantity of rounds is created automatically and in advance it is not known.
