Can't you do a Pro/parkour mode of any map/playtype combo?

I imagine that the Juggernaut mode will be popular for parkour

I bought one just because it was cheap, and got 700cry

I am guessing that if you were to buy an arbitrarily large number of these, at 10 coins each, you would get an average of 5 coins out of each of them. Edit: at least that's how typical gambling things work
