About Devil’s Number Online Slot

It’s you and the Mark of the Beast that must face off in the Devil’s Number online slot, created by Red Tiger Gaming. Set in a creepy library with a range of hellish symbols and bonus rounds you could land up to 12 Free Spins

Devil’s Number Online Slot Bonus Features


In the Devil’s Number online slot you can grab upgrades, which can be landed on any winning line. You must land symbols like cauldrons, books, skulls to have the chance to trigger the Mark of the Beast. It is these three symbols that will pay out a little more than the regular versions.


In the Remove feature you could get low paying symbols removed. If the Mark of the Beast burns on these low paying symbols they will then be removed from the reels. This also causes cascading symbols too, meaning that wins can be re-triggered. The low paying symbols or burned symbols won’t be present in this cascade.

Free Spins

The number 9 is the scatter symbol, so you may land the Free Spins found if you can land three number 9s on reels number 2,3 and 4. Do this and you will get 12 Free Spins. These Free Spins will take into account upgrades and removals, therefore the higher paying symbols could provide more wins.

Slotto Speaks

We are always a fan of Red Tiger slots, especially the dark ones. In the Devil’s Number online slot the unique upgrade features means that winning lines and possible Free Spins are maximised for excellent potential wins and value.
