Ratings and Reviews

great fun! great for brain development!


Challenging, fun, 'addictive', but most importantly, combines demands of hand-eye coordination with planning and therefore great for frontal lobe development regardless of one's age. This is the prime example of 'game' that is useful for promoting cerebral plasticity. In other words, eager young minds, this one is both fun and good for you -- and good for the parental units. As the minutes fly by, you will feel the synapses build. Get this one!

Fun to play!!


Fairly easy to understand from the get go. I am SO happy that you had the option to turn off off the FX! The heartbeat just about made me have a heart attack!! I did like the bag stacking sound, though, and was sad that I had to lose that with muting the FX! Wondering if there is a way to tweak with the app so you don't have the music pause.
I look forward to moving up levels!!

Frenzied Fun


The simple game mechanic is easy to learn and hard to master, making for plenty of enjoyment. New levels are challenging to unlock but each area is well designed and interesting to see. The difficulty curve may throw you off, but stick with it and you'll find a game to come back to again and again.
