The Frog (Slot Machine) Coins are useful only for Gambling, and you end up with bags and bags and well.. bags of coins.
Would you add a reward tab for the Quest book to trade the coins in for rewards or (For the gambling addicts:) Trade them straight up for more gambling? Aka "Enigmatic Die" 😄
Apparently Gambling is fun, and what's more fun for a gamblers than more Gambling?
The server we made already added an example for fun.
But we would need to add more options in the quest book for half stack, stack, and so on.
