Fuusio: puzzle app for ipad, iphone Review

Marko Salmela recently contacted me about his new puzzle app Fuusio.  You are presented with grids of different colors. Your task is to merge them to form 1 complete colored grid of the same color

The first few levels are quite simple. Then they get hard, very quickly.

There are 40-some tutorial levels where you will learn about action blocks: inversion, mask, swap, shift etc. Suffice it to say, it's easier for me to direct you to view the video.

You might think that all the 3x3 grids are easy. No! The 5x5 grids are multiple puzzles in one.

Fuusio is tough. I cannot simply play this while 'watching' the news. Full concentration is required.

Fuusio absolutely jumps onto the list of Best Puzzle Apps of 2012. If you finish all the levels, please contact me.
