Math Puzzle

I found this little game to be exactly what I wanted. I can spend hours playing addictive games on my phone... with very little benefit to myself or my health. Modern studies on old timers disease, aka alzheimers, aka senile dementia, suggest that thoughtful puzzles may delay or prevent its onset. There are caveats of course, such as they must be challenging. I'm not too good with numbers, and this app definitely helps me with my numbers. It's the only numbers game I find myself returning to.

First of all!!!! For everyone who says the games are too easy, I say keep playing. The earlier rounds are very easy, do get a little harder. When you get a chance switch to the genius level. There are NO easy rounds from there on. I absolutely love math and have spent days on some puzzles. That is not the whole level, just one of the puzzles in that level. So far I have only found one error in the game. That was in level 210. Great math game. Kids don't even know they are in math class.
