### 1/5 — 30 seconds and you're done

*2014-11-04*

Only one puzzle here. Don't bother.

### 1/5 — Not enough puzzles

*2014-01-16*

I just assumed for 99 cents this app would include many puzzles - like 20 at least.   It only has 3!   Not worth the price.

### 5/5 — Great app!

*2011-12-12*

Hope you create more different shapes in future versions!

### 1/5 — This is junk!!

*2011-05-03*

This has only 3 puzzles. Just this for $2!?!  Can I get my money back?

### 2/5 — Too expensive

*2011-02-19*

For what this is, it would be disappointing as a free app, let alone a reasonably expensive one.
It does teach you Pythagoras' theory, but the app is tiny, one screen containing three similar puzzles - that's it.
£1.19, what a swizz!!
