There is very little to be said when it come to the rules, as the game concept in itself is rather a simple one. Nevertheless, here are the game regulations you, as a player will defiantly face while playing KSquares:
You may only connect the dots on the grid if they are not previously connected by you, your opponent, or the computer.
To gain the points you have to connect the dots to form a square.
The square can be no larger than the four adjacent dots on the grid allow for.
Once a square is complete the player who draws the last line of that square is granted the right of possession over it. The square then is colored and the player is given a point.
The player who completes the square is given an extra turn which the player cannot forfeit.
