A free app for Android, by Large Animal Games.

Color Zen is an abstract, meditative, and relaxing game for the mind. It invites you to put on your headphones, relax, and find your way through the rabbit hole of bold and vivid hues and diverse shapes. It has no score, no penalties for failure, and nothing at all to pressure you into some expected result.

It introduces you to the concept or philosophy of stepping into something for the purpose of the journey, not the destination.

Figure out the puzzles in your own way, but remember that the purpose is relaxation, not perfection – so no sweat, no pressure please.
