The 8-ball joker is even more BS. I think I’ve only seen it trigger once ever.

I've read the source a few years back. It's all implemented fairly as it says on the tin.

I've long been suspicious of the RNG/seed implementation.. but not curious enough to automate testing of it, though.

It's been done, it's a valid RNG. It's somewhere on Reddit if you want to try and search for it.

I figured it had been tested by someone more motivated than me, haha, thanks! Will look for it when I'm back at a computer.
