I reinstalled it on my current phone and got hooked again like I was last time. It's one of those rare puzzle games that isn't just a pin-pull game like a lot of others. It's also offline, so I can play a cool impossible geometry game whenever. UPDATE: I just found out that 80 levels and endless mode are now paid. About a year ago, when I played this on my old phone, everything was free. Now I have to pay a 2.00 to get to what used to be free. Lowering my review to 4 stars for blocked content.

This game truly forces you to think outside the "cube", as it were. At first, I had a great deal of trouble getting my brain to think in what is essentially the 4th dimension, even with the instructional levels. So worth it, though. One little thing though, could you give me the option to adjust the music volume in game without having to turn it off? Every time I start it, I forget to turn it down and the music is just so LOUD.

It's exactly as advertised. It involves many levels based on the same mind-bending concept but with varying structures and complexity. It's also quite simplistic, with no fancy sound effects or distracting visuals and no annoying ads (at least as far as I have played, which is ~40 minutes) The only reason I don't give 5 stars is because it's too simplistic for my taste. The levels begin to feel repetitive. It's the same concept over and over.
