How to free captives? There is slots for gems but no hints as to what goes in them...
If you look closely the gem slots have a slight coloring as a hint. Also on the frame of the machine there is a hint scratched.
Thank you! I have this weird issue where it's difficult to tell apart similar color tones. I'm not color-blind, but for gaming purposes I may as well be. I'll take a closer look now...
