Fuck, you just reminded me of that game. It fucking rocked for one simple reason.... candy.
In the 6th grade, they had it on the old ass computers (one year before they upgraded to stuff with Windows and shit). Every Friday, we got a choice between Oregon and Number Cruncher, we all picked Number Cruncher, cause the teacher would give you choices of candy based on the points you racked up in that game. And holy shit was I good at that game. I would walk out of that classroom with hordes of candy. Sell some off for quarters, eat some, hand off the rest to friends. Good times, good times...
