Ah, Treasure MathStorm. I have a few copies of that one too. I was already past its content by the time it came out but have seen it in action and may use it with at least one of the kids I tutor, probably sometime in the second semester of this school year.

I just ordered Dr. Quandary from Amazon to use with students who struggle with patience/persistence in problem solving. I remember playing it at computer camp when I was young. It was an even better deal: 50¢.
