Drawing Squares

Drawing Squares is the logic game that will blow your mind!
It is a logic game inspired by the classic pen and paper game Dots and Boxes. Do you remember the game you used to play at school? (also known as Boxes, Squares, Paddocks, Pigs in a Pen, Square-it, Dots and Dashes, Dots, Smart Dots, Dot Boxing, or, simply, the Dot Game).

Instructions

The point of the game is, to complete a square on the graph paper on your classmate behalf. To do this you must draw a line where your classmate WILL NOT take advantage of your move and complete a square. The game ends when no more lines can be placed. The winner is the one who scores the most points.
