The potion icon is the game’s most rewarding symbol - land 5 in combination and you’ll pocket a jackpot win of 666x your stake. However, you can also win 2,500x your stake on every spin or extra spins with the upgraded payouts feature in action.


You can play for stakes of between £0.20 and £100. Use the bet slider to indicate your preferred bet amount.  

Your icons consist of skulls, cauldrons, spell books, scrolls, and card values 10 through to Ace –  the top paying icons have two different payouts. They pay out in the same combination as standard icons but also offer higher wins when they show as being on fire.

Fire icons: After a line win consisting of one of the pictorial icons, the skull with 666 may appear and turn them into burning icons for the bigger payout.

Remove Feature: after a win with any one of the card values, the skull with 666 on it may appear and burn away one of the low-paying icons. It will also trigger cascading tiles for more win opportunities at a higher payout.

Extra Spins: land 3 of the number 9 icon on the 3 central reels and they’ll invert to show 666 - the Devil’s Number! Receive 12 extra spins, with Upgrade and remove features in action. You can also retrigger the extra spins round.
