The point of the game is to surround your opponent by the way of connecting your dots around theirs within at least one cell from each dot. The "prison cell" can be in any shape or form as long as the dots are within one cell distance from each other to connect them. If you are playing against a computer the default difficulty level is set to 1 and can be increased to 2 and also the default setting for winning the game is 5 minute countdown which can also be changed in options to a 50 point game or an unlimited game (great for playing against other person). Have fun!
