Excellent platform for anyone interested in exploring mathematics as a means for critical and creative thinking.

This is a neat environment to practice geometry tricks in. Lots of content, never feels repetitive. The free version lets you access all puzzles as long as you're persistent, which I appreciate. My only complaints are that in some puzzles involving perpendicular bisectors and circles it can be hard to formally prove your answer is correct (instead of shrugging your shoulders and accepting that the game said you did it correctly), as well as that some of the longer puzzles (more than 8 E) could use draft hints for when you really can't figure it out from the E sequence alone. Still, a great and educational lunch break game.

Tutorial went fine then refuses to do anything on first puzzle. A shame.

A friend told me about this app and then an hour latter I’m standing in my doorway just playing the darn thing. It is amazing compelling, and addicting. It’s all the good fun parts of geometry without any pressure. It is just pure fun.

I concur with all the great reviews here. However, why won’t you just let me know when there is a second solution available for an extra star. The problem is that the definition of “a second solution” is not defined, so if I want to score all the possible stars, I have to spend enormous amounts of time looking for solutions that aren’t there. And sometimes I find a unique solution that apparently the authors didn’t think of so I get no credit. I understand they want to sell in-app purchases, but I just want the satisfaction of doing it all myself. Please, just let me know if a separate solution exists so I don’t have to spend hours of monotony looking for solutions you don’t consider unique!

It's a great puzzle game and it's helped me learn a lot about geometry. It would be really awesome if the game allowed me to share solutions with friends. Answers are always available on YouTube but that's not the point. It would be a lot of fun to use the game socially.

Challenging puzzles with many constructions I never learned in school. Excellent design work without the time-wasting animations you see in some other apps.
