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 man's 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.
