Really fun. Puzzles are fair. Most are pretty straightforward but a few require a bit of cogitation. My only complaint was that it wasn't longer. But given that the game is free and you can complete it without watching any ads, I can hardly complain. Best of all, there are no gems for logging in or rankings or any of that other mobile game cruft. Just solid little puzzles!

My favorite thing is that there are no forced ads. If I want a hint or the solution, I can watch an ad. I take it as a challenge; if I have to watch an ad, the developer earned it! The game is numeric pattern recognition, not math homework. 100 levels of varying difficulty. This is exactly what I wanted - a simple game that let's me practice some skills that I haven't been exposed to in quite some time.

The puzzles got hard at first, but then they fell into this archetype for most of them, taking away the puzzle aspect of it. The numbers were also too small and therefore too easy to manipulate mentally. Too easy, plus it didn't go into decimals and didn't include too many elements. The format is also very easy to exploit, too. Theoretically, someone can just keep pressing numbers 1 - 100 until they beat the level for most of them.
