Are you ready to journey into an abstract world of colors and shapes? Then welcome to Color Zen, a relaxing puzzle game with no scores and no penalties for failure…just simple rules, intuitive controls, and awesome puzzles to keep you busy for hours on end.
Flow Free is similar, just with a grid. Too bad you (almost) always mention non-free stuff...
