Is it a game? Is it a tool? Decide for yourself. I only know it's relaxing, addictive (sorry), beautiful* and fun.

 
 

Get the app

The App is available for iOS and it's free with all features included. It comes with four free tile sets and a few additional tile sets for 0.49 Cents each – but trust me: The app is a lot of fun already with all the free tile sets activated. The cover artwork at the top of this page for example has been created with only the free sets. Give it a try.
