On the wiki it says that to obtain the Evil magikarp badge you need
to lose over 10,000 game chips at the coin flip, I dunno if the
wiki is wrong/needs to be updated but ive lost over 20,000 game
chips and I've still yet to receive the badge.
I see there has been an error in my judgment
To be fair though it just says lose 10k chips on the wiki and
doesn't specify which coin to bet on but yeah I see what I did
wrong
