Our rating:
  • A more unusual slot with a really interesting, dark theme
  • A couple of base game features which work well with the free spins
  • Quite a fun game overall with some decent wins

Devil’s Number slot is a new, creepy game made by the devil himself. Well, it’s actually been developed by Red Tiger Gaming but that’s not a bad thing as they’ve made a lot of great slots in the past.

This one, as I mentioned, is a dark-themed slot based on that infamous number, 666. It’s a spooky design with dark symbols and a creepy background. The graphics are pretty good and, while it won’t be to everyone’s taste, I like how it’s a bit different and stands out. You have a fairly standard 5×4 set of reels with an RTP of 96.06%. Your goal is to get a winning combination from left to right using the base symbols, just like any other slots. You do this with the following symbols, ranked in ascending order based on their value:

  • 10 (lowest value)
  • Jack
  • Queen
  • King
  • Ace
  • Scrolls
  • Book
  • Cauldron
  • Potions (highest value)

Devils Number Slot Bonuses and Features

Mark Of The Beast Feature. This feature is triggered in different situations. When you get a win line with the Scroll, Book, Cauldron or Potions symbol, the Mark Of The Beast may burn and upgrade the symbol so give you a better payout. If, however, you get a win using one of the lower value symbols (all of the symbols with a lower value than the ones just mentioned), the Mark Of The Beast may burn and remove the symbols after it has paid out, causing symbols to fall in from above.

Free Spins Bonus. If you land 3 of the same symbol on the middle 3 reels at the same time, you’ll trigger this Bonus. You’ll get 12 free spins, and the Mark Of The Beast is active throughout the Bonus. Better yet though, a low value symbol that is removed with be removed permanently for the Bonus. Equally, an upgraded symbol will remain upgraded throughout the Bonus. You can also retriever the Bonus in the same fashion, getting quite a few free spins in the process.

Devil’s Number slot from Red Tiger Gaming is a dark new game with some interesting features that take advantage of the theme to make gameplay more interesting. The Mark Of The Beast feature is pretty cool. It can give you some decent payouts during the base game, but it’s the Free Spins Bonus that makes the most of it. That’s because the effect lasts the whole Bonus, and you can win more free spins too by retriggering the Bonus. The slot isn’t the most exciting one I’ve ever played, nor does it offer the biggest rewards. However, the payouts aren’t bad and it is a bit different to the norm, so it’s worth giving it a go and seeing what you think. You can check out their other slots here.
