I saw my nephew play this. It’s a great idea but I found the implementation lacking. He got stuck on a level where he had to solve a simple equation, and tried to do it in the “wrong” order. He eliminated an unknown from one side first, and then the system wouldn’t allow him to do the type of operation necessary to complete the other side, maybe because that particular technique hadn’t been taught yet. It would have been a perfectly natural way to solve the equation on a blackboard. I could see they probably wanted him to do the other side first. My nephew tried the same basic approach 3 times in a row, and then gave up and threw the tablet down and went off to play with Lego or something.
