Uh, wow.
So simple, so addictive. So awsome. Only played for 10 min so far and this has to be one of the best games I have played to date.Rosenblumr
Simple yet perfect
It's an easy puzzle game to pick up and is well worth the $1. You can always tell when an app had a good amount of work put in to it. The graphics are simple yet look very polishedSnowboarderX

It's a great game, but once you've played it for a while, it gets too easy. Let's add another difficulty, no?Alan Yepez

I love this game!
If I'd had this game in elementary school, I would never have become math-phobic! NineGaps is easy to understand but very challenging, even at the simplest level. The graphics are clean and attractive, and who doesn't appreciate a big "YAY!" when you get the answer right?! One of my top 3 favorite iPod games.Show lesssnarkypantz
PEMDAS out the window
This is a terrific game and would've received 5 stars but for one thing. As a math teacher, I have one major criticism. The game does not follow order of operations, or PEMDAS. The answers along the perimeter need to be calculated using PEMDAS.Krarf
Work little grey cells
Keep your grey cells on their toes thanks to this fun smart-looking challenging mathematical app. Perfect for short sessions and looks great! What more can you ask?Karuko
Brain twister
This game reminds me of Sudoku. It's different enough to keep you coming back and you can get thru a game alot quicker then Sudoku. So is perfect for those subway rides to work. Definitely pick this up.Maelef
