I've seen this number change between 50 - 70, and I have no idea what's getting me these coins. I've tried changing settings, tried modifying the amount of players, the CPU's levels, etc., and it seems the numbers are always random each time.
Is the number of coins I get after each match just randomized? Or is there some factor that effects it? What determines how many Smash Coins I get at the end of a match
