Description:
40 muh coins for 10 spins, 10 spins that are rewarded in the time it took to be rewarded for 1. This option is to let us throw away coins gamble at slots faster.

Why is this a good idea?
I usually spend 2000 muh coins at slots whenever I have a surplus of coins. Even if you have a smartcast button with no skill in it to continually click roll, it still takes a while. A good long while where I can’t take my finger off the smartcast button. If this gets added, we can now spend 20000 coins in the time it took to spend 2000.

What risks or downsides does it have?
No downsides besides doing testing to ensure the hamster that runs the server isn’t harmed by it.

Hmm.. why not just skip a step and let us roll our coins at once? Not everything is about efficiency. Gambling certainly loses its effects when you start batching the gambles.

Unfortunately this is a -1 from me.
