Very Good Game - Especially if you like math

I think this game is very well designed, and the mechanics are fun. It makes me think mathematically, and I like that each level is quick (they do not require a ton of time to complete).

Super Addicting

I don't have many games downloaded on my phone and this is one of few that I really enjoy. The concept is simple, but the game isn't. Yes some levels are easier than others but overall it's a fun challenge that's very addicting.

I ultimately gave a rating of 4-stars because of the wait time at different intervals (and I'm not paying to unlock immediately; it's a waste IMO).

One final note -- level 97 is not a "fix." There's a way of beating it.

Great game. Unfortunately...

Unfortunately after beating 40 levels, you either make an in app purchase, or wait 4 days. I can understand it is a free game and that the makers want to make some money. But coming from someone who is perfectly willing to wait for a bit rather than spend a couple bucks, 4 days is a lot of time. A lot. As in enough to make me delete it. This game deserves 5 stars, the company who made it... deserve much less.
