Needs upgrade I loved this app! But now it needs update with more challenging levels and more interactive modes.

Good but room for improvement Would be better if the answers were explained.

Too few levels and too little variety. Great while it lasted, though.

Pretty good game. Definitely like that they give you correct answer now when you run out of lives.

It's a good game, but they need to give you instructions and if you make an error, they need to show you what i did wrong and how to get it the next t

Like the puzzle but it keeps starting back at level one when I exit and go back later. And needs a built in calculator for complex math.

Boring App :/

Not bad overall but needs more levels, ends too quick

@Cheri: x_n = x_(n-1) - n^3 Also, some sequences have multiple solutions! I lost one of my lives that way.
