There are games that offer free playing, only to capture you with their unending advertisements. And there are games that only have a short amount of free playing. But, not this app. This app has 375 levels of free play and that's more than enough to satiate your puzzle solving addiction. Yes, there are in-app purchases that will take this app to another puzzle paradise. For now, I'm only about 150 puzzles down and over 200 to go. Just connect all of the color dots together via the same color and solve the puzzle. Oh, it's harder than it sounds. Try it out, play it, solve and get hooked.
