Warning: Avoid this slot when you’re home alone at night. Despite the slot name being a bit of a giveaway, I was quite taken aback by the committedly satanic theme.

But today’s slots are all about variety. For some people that means ponies and butterflies, and for others, it’s cavorting with fiery demons and devils.

Once I got over my initial surprise, I delved into Devil’s Number, brought to us by Red Tiger Gaming and promising to deliver up to 2,500 x your bet. With 5 reels and 30 paylines, I was excited to find out how close I could get to the top prize. Read on to and see how I got on with The Beast.

Theme and Background

Devil’s Number fully embraces everything that comes with the dark arts. It’s set in a very upmarket but deeply sinister home library, the kind of room that might conceal dungeons behind bookshelves…but perhaps I’m letting my imagination run away with me.

Across the reels are comic book-styled graphics, and you have to give kudos to the designers for the impressive artistry behind each one. The skull potion symbol is one of the top payers, delivering anything from 3, 6 or 12 times your bet depending on how many you land — but more on this later. There’s also a bubbling cauldron, a book of spells and some ancient scrolls. The symbols are also accompanied by the usual low value A to 10 royals, but these have been designed up to fit the theme extremely well.

The number 9 also appears and a set of 3 will trigger the most valuable special feature in the slot — but again, more on this below. The music is a combination of creepy echoing laughter, eerie silent undertones and full blast heavy metal music. It switches up depending on what’s happening during the game. The result is a very effective combination of eerie trepidation and downright rage.

Gameplay

Devil’s Number offers players the opportunity to cash in up to 2,500 x their stake. After playing the slot for a few minutes, it quickly became obvious that the only way to hit that high is by triggering a sequence of the game’s special features.

DN Symbol - Upgrade Feature

Upgrade Feature

This feature is triggered randomly during a spin in both the base game and during the special features. As the name suggests, it will upgrade your winning combinations with any of the high paying symbols that also appear.

The high paying symbols are the scroll, book or skull potion. One of these will be selected to replace your winning symbols and boost your overall win.

DN Symbol - Remove Feature

Remove Feature

This is another special feature that’s also randomly triggered. If you form a winning combination with low paying symbols, this feature could be activated and set about vanquishing those low payers.

The remaining symbols on the grid will drop down and new symbols will appear to fill the gaps, giving you a fresh chance to win bigger than before.

DN Symbol - Free Spins

Free Spins

Where usually numbers on the reels would be considered low-paying symbols, Devil’s Number has chosen to employ numerals a little differently. If the number 9 lands then you shouldn’t be dismissive, as three 9s will activate the very rewarding Free Spins feature. The 9s will flip over to form an ominous 666 across your screen and you’ll then be awarded 12 Free Spins.

This feature also incorporates the upgrade and remove features, so that you’re making boosted wins at a very high rate. All wins formed with high-paying symbols will pay out at an increased rate, and the low paying symbol wins will disappear and cascade as they do in the Remove Feature described above. The even better news is that the feature can be re-triggered. Land another three 9s during your free spins and you’ll get an additional 6 spins gratis.

Payouts and Wagering Limits

The maximum payout is 2,500 times your bet in a single spin, that’s a maximum win of C$100,000 on a C$40 bet. But even with low value bets, the potential remains alluring.

The Skull Potion symbol is the highest paying, rewarding players with 360 coins for 5 of a kind, boosted to 666 coins (groan) if you hit on the Upgrade feature. The Book of Spells follows with 180 coins, upgraded to 360 coins.

To cash out up high you really want to trigger the Free Spins feature, where the win potential is massive and can also be re-triggered. While the numbers sound impressive, this isn’t a get rich quick scheme.

Red Tiger Gaming have built Devil’s Number at a 5 out 5 volatility level, so you’re in no way guaranteed a sizable win, though of course a windfall is entirely possible. I would advise placing your bets carefully, and employ some smart bankroll management. If you’re resting on a budget, eke out those bets as much as possible to hold out for those beautiful three 9s.

Final Verdict

Devil’s Number

72%

Without a doubt, Devil’s Number rolls onto our screens as a definite acquired taste. I think it would even be fair to say that some players might be offended or made uncomfortable by the theme.

However, if you’re not sensitive about the occult, then I would feel confident in recommending this slot as a great opportunity for a sizable win. The special features are not only interesting, but also rewarding.

The decent 96.06% RTP means that if you do hit on those winning combinations you have a genuine chance to recoup your stakes and make a nice profit on top.

Of course, Devil’s Number is set at high volatility so you could find yourself both well above and well below your investment. Proceed if you dare.
