A widely known Paper-And-Pencil game in a web skin.

A very simple game to start with, which however may develop sophisticate and matematically involved strategies.

Draw a box side from one dot to one of its neighbours: the player who draws the 4th side of a box claims it and draws another side. The player who claimed more boxes wins.

Pie rule: some board sizes have the variant with the so called pie rule; with it, player 1 may play up to a certain number of moves (currently 5) alternating the colour; when he runs out of moves (or decides to stop), the other player chooses between swapping the player colours or keeping them as they are; this also decides who is going to play right after; after this, play goes on normally alternating player moves.
