12. Toro is a Walking Wild symbol that only appears on reel 5. The Toro moves leftwards until he spins out from the first reel, generating one respin for each step.

13. Book symbols are kept sticky as long as at least one Toro is in view. A potential Bonus mode will be triggered when all wins have been paid out and all Toro symbols have left the screen.

14. Two or more mummy symbols trigger Mummy Respin. The mummy symbols lock into position and stay sticky during the following respin.

15. Additional mummy symbols appearing during ongoing Mummy Respin might prolong the respins. All Mummy Respins end when a Toro appears.

16. Landing a Toro when mummy symbols are in view or landing one or more mummy symbols when the Toro is in view, trigger the Toro Goes Wild feature.

17. During the Toro Goes Wild feature, Toro moves vertically and then horizontally to knock all mummy symbols off, leaving wild symbols behind. Toro continues to attack until all mummy symbols are defeated.

22. At least two instances of a high or mid value expanding symbol, or at least three instances of a low value expanding symbol, on inpidual reels are required to trigger the scatter pay feature.
