This is not my experience. If they see the task as “solving the problem is success and anything else is failure,” like they might be used to from most school math classes, sure. If you set up the context properly my experience is that most kids enjoy working on hard math puzzles.
Perhaps on basic math with younger kids but I expect this will hit a wall at a certain level. Or, the audience of kids doing this is already a skewed/biased sample of kids that just love math (or it's parent driven)
