What is Mystery Symbols?

A mystery symbol appears on the reels as one icon, sometimes a question mark, then changes into another.

For example, a low-paying lemon might transform into a high-paying cherry. Mystery symbols sometimes guarantee wins after transforming, but this isn’t always the case.
