Contrary to the most popular online slots that feature light and cute themes, Devil’s Number is the slot that will give you the creeps. Starting from its title and going all the way to its symbols, this Red Tiger Gaming’s game is an incredible representation of what the human mind is capable of imagining when it comes to spiritual things such as heaven and hell. You’ll see hell in this slot from the devil’s eyes, and you’ll be amazed by what you’re seeing. 

Bonus Features

You will benefit from three special features in the slot, the Free Spins, the Symbol Removal, and the Mark of the Best. The latter is an upgrade feature that triggers at random during any spin and transforms high-paying symbols into symbols with boosted values. 

The Symbol Removal triggers a chain reaction, where the symbols that form a winning combo are removed from the reels, and other symbols cascade from above, giving you a second chance for improved winning combos.

The most significant thing is that you trigger the Free Spins not with Scatters or Bonus symbols like in most Free Spins slots, but with the lowest-paying playing card symbols in most slots, the 9s. You will need 3 of them, and as they show up, naturally, they turn upside down and reveal the Devil’s Number, 666. A heavy metal soundtrack kicks in, and you are rewarded with 12 Free Spins. The two previous features apply here, and the Free Spins are re-triggerable. The game can deliver a 2,500x stake payout potential.

RTP & Volatility

Devil’s Number is a medium to the high volatile slot. You could get to the 2,500x the stake potential if you manage to go through the bonus game. It is where the game is most rewarding. 

RTP-wise, you will get a 96.06%, which is devilish, we know, and maybe that was the developer’s point, to link the RTP to the devil’s number. 

Massive Win Video

The betting starts at $0.20 and goes up to $40 in Devil’s Number, the 30 payline, five reels online slot. The maximum payout potential, as mentioned, is 2,500x the stake, so for the max bet, you could win $100,000. That's a fantastic win for a max bet that is as little as $40.
