This game is really fun! the levels are challenging and make you think inside and outside the box. the only reason I didnt give it five stars, is the ads! ads pop up to much along with the prize wheel. I love that you can get hints but you dont need a reminder EVERY SINGLE RIDDLE! Its just ridiculous! Please fix!

This is a very good game. The puzzles aren't too hard, and it's fun all the way through. There's also a variation of puzzles and that keeps it interesting. I also love the way they set up the hints wheel, with escalating increases (2x, 3x), so so it's easy to rack up totals...I just wish they had this system in ALL of their games! Great job, developers!

It's a big app that takes up massive amounts of storage. Although it is entertaining and a good brain exercise, the ads are overwhelming. The "draw an object with one line" games don't seem appropriate to the core goal of the game, however they require critical thinking skills - whatever. It does make you think (outside of the box), and I'll keep playing for awhile, but I can't say it's one of my favorite games. When I need to free up space, it will likely be one of the first apps to be deleted.
