Picma Squared is a set of grid-based puzzles that play out like a cross between Minesweeper and Picross. Numbers of each gird show how many colours squared are in that area, and your job is to fill the grid appropriately.

The small 3x3 and 5x5 grids are simple enough, even when extra colours are thrown in. Once you get to the 10x10, however, that's when it gets tough. Each completed puzzle will show a picture, and as with Picross, it's entertaining to watch a load of scribbled in blocks suddenly become an actual object.

You can also create your own puzzles, although you'll need to create an account to do so. You also need to pay monies if you want access to every puzzle, although most people will be able to get enough enjoyment out of the free puzzles.
