NO ADS, relaxing, free. All of that makes up for what may be perceived as flaws. I'm fine with the UI and play style. I also realize that designing and maintaining this app probably isn't the only thing on the dev's plate.
Works well, puzzles are addictive, but latest update has a bug that switching to a different app causes a black screen when the app is opened again, needs to be closed and restarted to work properly again.
Addictive, relaxing and challenging at the same time. Love the fact they've included four game modes. It's also aesthetically pleasing and neat looking as there are no ads. Just perfect!
Weird UI :|
It is beautiful. A perfect time killer with no ads inside.
Great free puzzle game.
