I had an idea for a slot machine game that used in-game currency. I looked at the community guidelines and saw no information. I also looked at the wiki, nothing. Please answer as soon as possible. Thanks!

I think this would be allowed. Why wouldn't it be? As long as there aren't any inappropriate casino elements, you should be fine.

What would qualify as an inappropriate casino element?

Like a bar in the background, or something like that. Likewise, any sexual themes are prohibited.

@Paddle2See, a Scratch Team member, has a Roulette project: https://scratch.mit.edu/projects/650309/

Note that it is to demonstrate “the evil dangers of gambling” and it is hard to win much.

I'm pretty sure it's allowed, several ST members has made gambling simulators themselves.

Yes, that follows the guidelines.
