The method the Crystal is Randomly Selected
The game chooses the Crystal symbol at random. You cannot influence its choice, and it is reset for every single free spins round you activate. That uncertainty is part of the fun. Your Crystal may be a lower-value character, or you could be fortunate and have it be the top-paying Anubis or Horus mask. This chance is typical for slots licensed by the UKGC, assuring fair play. Each bonus round is a fresh start with a fresh Crystal, so things are never predictable.
