Dots: Divide et Impera

Play Dots: Divide et Impera with artificial intellect!

The game is played on a grid of finite dimensions. You can choose the grid size in the game settings. Players take turns making dots of their own colour. At each turn, a player must make a dot at an intersection of the grid. This dot has to be free, therefore it must not be on another dot and can not be part of a territory. You can also enclose a whole closed territory for yourself. You can make a territory of any size by making dots in a circuit that can be connected by straight or diagonal lines, one space in length. If there are no obstructions in the circuit (e.g. lines, opponents' dots) then a line can be drawn connecting the dots in your color and the space inside is your territory. A line can not be drawn until the dots are able to complete a circuit. Before the line is drawn, you can intersect their line diagonally and claim territory before the opponent can.
The game ends when a player can no longer put a dot anywhere.
