I don't get it. I am doing these things for fun. How is not doing a problem a reward?

scenario #1: you run into a problem that you really like but no matter how hard you try you do not seem to be able to figure out how to solve it. You are ready to "give up" but would *really really really* like to see other players' solutions and learn from them. Unfortunately Cody does not let you see other people's solutions until you provide one of your own. A freepass allows you to bypass this restriction (from time to time and with a little effort from your side so it does not break the logic/motivation of the game)
