Love this game❤️!

I love this game and how challenging some of the levels are. It helped me study for my angles test. It is also fun with all the colors and you can write on the screen with your finger to solve it! So that makes it much much easier to do the work for the problem. Keep up the great work!

Love it UNTIL...

So it’s great if you know the answers. Makes you feel really smart.

However, the clues are not helpful. The two I’ve looked at so far have been inaccurate or incomplete. And at some point you should be given the option to see the solution with an explanation. Otherwise it’s simply a way to feed your ego. You won’t really learn anything.
