AppMoku (advanced TicTacToe)

AppMoku is a board game played in a 20x20 grid. It is a slight modification of a classical Japanese board game Gomoku.

AppMoku is a 2 player game played in turns. Each player has to put one symbol into a remaining free cell per turn. Your symbols are always marked as "x" and "o" always mark where your opponent has made his moves. Player who first manages to put 5 of his symbols side-by-side into a straight line - wins. It does not matter whether symbols are put horizontally, vertically or obliquely.

During the game it is not possible to remove or replace any symbol that has already been put into grid. If the grid is filled and nobody was able to reach 5 symbols in a row - it is considered to be a draw.
