Devil’s Number Slot Review

Devil’s Number Slot Overview

As soon as I loaded Devil’s Number from Red Tiger Gaming, the gothic library backdrop and comic book style graphics set the tone. The slot runs on a 5 reel, 4 row grid with 30 fixed ways to win, launched in April 2019 as a darker alternative to brighter games. Everything circles around the occult feel of the number 666, helped by the brooding soundtrack and fiery animations on winning spins.

For me the appeal lies in how straightforward the mechanics feel while still giving that suspense you want from a high variance slot. There are no wilds or complicated side games, just cascading wins, symbol upgrades and removal, plus a free spins round that turns the Mark of the Beast into the star. It plays cleanly, suits quick sessions, yet can still throw up some tense bonus streaks.

Devil’s Number RTP, Variance & Technical Data

On the numbers side, Devil’s Number usually runs with an RTP around 96.06%, though I have seen a lower 95.05% quoted as well, so casino settings can matter. Volatility is high, rated at the very top of Red Tiger’s scale, and you feel that straight away. Base game stretches can go quiet, which suits players who like bigger single hits rather than frequent small pays.

Stake levels tend to start at small bets and run up to higher limits, commonly around 0.10 to 20 per spin in the versions I have played. Official max win figures vary between about 2,500x and 5,520x your stake, while some reviewers talk of wins up to one hundred thousand pounds. Either way, the game sits firmly in the high risk, high reward bracket.

Devil’s Number Symbols, Paytable & Paylines

The paytable in Devil’s Number sticks to a simple structure that I find easy to scan. Low paying symbols are the card ranks 10, J, Q, K and A, styled with a dark twist and paying between about 1.2x and 2x your stake for five of a kind. Wins land from left to right across the 30 fixed paylines when you hit three or more matching symbols.

High paying icons carry the theme harder. Scrolls, spellbooks and a bubbling cauldron sit above the card ranks, while the bottle of magic potion with a skull stopper is the top regular symbol, paying 12x for five in a line, or even higher once upgraded. Stacked symbols can appear, which, mixed with the avalanche wins, gives the paytable more punch than the raw numbers first suggest.

Game Features in Devil’s Number

Feature wise, Devil’s Number leans on the Mark of the Beast mechanic. Any win triggers an avalanche, with winning tiles removed so new symbols fall into place. When the win uses low value card symbols, the Mark can flare up and remove those low icons completely before the next cascade. I like this twist, as the grid then refills with only mid and high value symbols for another crack at a hit.

When you land a win made up of high paying symbols, the Mark can instead upgrade them. I have seen the magic potion line jump from its usual 12x to over 22x thanks to this, which can turn a decent spin into a serious payout, especially with multiple avalanches. Because both removal and upgrade can repeat during a single paid spin, base game streaks can feel almost like a mini bonus.

The main feature, though, is the Mark of the Beast free spins round. Land three Number 9 scatter symbols on reels two, three and four and they flip to show 666, awarding 12 free spins. In this bonus, any low symbol win removes those cards for the rest of the round, while high symbol wins upgrade their values permanently, so by the end you can be spinning on a brutally rich grid.

Devil’s Number Mobile & Tablet Experience

I have played Devil’s Number on both desktop and mobile, and it holds up well on phones and tablets. The 5x4 layout fits nicely in portrait or landscape, the buttons are clear, and the animations do not feel cluttered on a smaller screen. With earphones in, that sinister soundtrack works a treat during late night sessions when you want something moody and atmospheric.

Verdict on Devil’s Number

As a regular slot player, I see Devil’s Number as a high volatility game with a niche but very well delivered theme. The lack of wilds or complex side games keeps things straightforward, while the Mark of the Beast, avalanches and free spins give enough depth for long sessions. The max win is not the highest for a risk heavy slot, yet the atmosphere keeps pulling me back.
