Devil's Number Slot Overview
Devil's Number is a gothic-themed video slot from Red Tiger Gaming, released on 2019-04-11. It runs on a 5-reel, 4-row grid with 30 ways to win, leaning into an occult library setting and the recurring motif of 666. The presentation is described as comic book-esque, with a dark palette dominated by red and black and a deliberately sinister soundtrack.
Mechanically, it is positioned as a high volatility game with two win-shaping features active in the base game and carried into free spins. Published staking varies by listing: one set of figures quotes a bet range of 0.10 to 20, while another references a maximum bet of GBP 40. The emphasis is less on complex side modes and more on modifying standard line wins.

Devil's Number RTP, variance & technical data
Reported RTP settings for Devil's Number vary between 95.05% and 96.06%, suggesting different configurations in circulation. Volatility is consistently labelled high, including a 5 out of 5 score on Red Tiger's own scale. A hit frequency of 17.82% is also quoted in one summary. In practice, the combined picture points to intermittent payouts and the need for bankroll-aware staking.
Devil's Number symbols
Devil's Number uses nine symbols in total, splitting clearly into low and high value groups. Low pays are the card ranks A, K, Q, J and 10. The four themed premiums are scrolls, a book of spells, a witch's brew cauldron, and a skull-capped magic potion. Wins form from 3 to 5 matching symbols across the 30 ways layout.
Pay examples given for the premium set include 4x for five scrolls, 5x for five books, 6x for five cauldrons, and 12x for five magic potions. The lower card symbols pay between 1.2x and 2x for five-of-a-kind. Several descriptions also note stacked symbols and a cascade-style flow when the relevant feature triggers, helping the reels refresh after certain wins.

Devil's Number bonus features
Two core modifiers drive the feature set in Devil's Number, both tied to the Mark of the Beast. The Upgrade feature can trigger at random after a win involving one of the four high-paying symbols, increasing the value of that winning combination. One example cited is a five-potion win rising from 12x to 22.2x, which frames Upgrade as a direct payout booster rather than a separate bonus round.
The Removal feature is associated with wins from the low-paying card symbols. When it triggers, those winning low symbols are removed and replaced, creating an extra chance to extend the spin outcome. This is described in cascade terms, with new symbols dropping in to potentially form additional combinations, shifting some of the game value into chain reactions rather than single-hit line wins.
Free spins are awarded for landing three scatter-style triggers on the three middle reels, described as a Number 9 symbol that flips to reveal 666. The round starts with 12 free spins, and both base features apply throughout: low-symbol wins remove those symbols for the duration, while high-symbol wins upgrade values permanently during the feature. Retriggers are possible, with one account stating three more scatters add six extra free spins.

Devil's Number verdict
Devil's Number is defined by its theme as much as its maths: a stylised, cartoon-dark take on occult imagery that will not suit every audience. From a gameplay angle, it keeps the structure straightforward while using Upgrade and Removal to add momentum in both the base game and free spins. Max win figures are inconsistent across published summaries, ranging from around 2,500x to 5,520x, and there is no progressive jackpot.
