TicTacToe Super Glow

TicTacToe SuperGlow is a free game that is a puzzle that resembles a game of tic-tac-toe. But, despite the name, here is a completely different principle.
There is a playing field consisting of a number of squares. The user himself chooses the size of the playing field (from 3х3 to 33х33). The larger the field size, the longer it will take to play. Each player makes one move, placing a line on one side of the square. The task is to fill all 4 sides of the square with lines - in this case the player who closed the last side gets 1 point, and in the closed square appears his symbol. The player with the highest score (closes most of the squares) wins.
The game can simultaneously participate up to 4 players. There is a choice between a human player and a computer (easy or difficult difficulty).
