Metasquares Plus

Metasquares is a pen-and-paper game. Two players take turns claiming a dot on a large pre-drawn grid. Whenever one player creates a valid square (including those on an angle from the grid) they receive points equal to the area of the square. The game ends when all of the dots are claimed. 

This game works exactly like the pen-and-paper version but automatically calculates the squares and the points gained. The app also allows for dynamic sizes of the grid and more than two players.

It is highly inspired by the flash game originally on htwins.net
