Square Zen is the most simple game you would find.
No signup, no tutorial, no interruptions or distractions - download & start playing.

Just like life, in Square Zen, you have to make the best of what you have. You get pieces of different shapes that need to be arranged so as to fill a big square - and you get points!

That's it - challenge yourself to make the best score you can.
Its competition is with the person that matters ... YOU.
