A fun easy way to start work on your clarity, focus and attention.

24 levels from very easy to very hard. Master each level by solving 6 puzzles - you are allowed three tries in each of the first three, two tries in the next two and, finally, you must solve one puzzle in a single try. The level is then open for free play with three tries forever. Only 24 ads in game: You have an opportunity to watch a :30 ad to get 2X points to help you run up your score. Larger levels have 1000's of puzzle variations making it a game you can play over & over.
