Devil's Number Online Slot Review

Win up to 2,500x your bet in Devil’s Number, Red Tiger’s spooky 5-reel slot! Step into an ancient library and start spinning to pick up cash prizes, win free spins, or potentially upgrade symbols to boost your payouts. Read on to discover more about Red Tiger’s eerie game in our Devil’s Number slot review! 

Devil's Number Slot Details and Features

The Devil’s Number is played on a grid with five reels, four rows, and 30 fixed paylines. Red Tiger has included two unusual features that help Devil’s Number stand out, which cause certain symbols to become upgraded and others to be temporarily removed from the reels for bigger payouts. 

The Devil’s Number mobile slot is set in a beautifully Gothic library filled with hundreds of books. A human skull sits on one shelf, while an ornate bust of the Devil himself stands to the left of the reels. At the bottom of the grid, an occult symbol featuring ‘666’ (the Devil’s number!) has been applied to the chequered floor. It’s a brilliantly detailed setting with a cartoony visual style, and the low-key, eerie music reinforces that deeply spooky feel.

Game Symbols 

The four top-paying symbols in Red Tiger’s Devil’s Number casino slot may pay out higher prizes when upgraded (which we’ll get to later in our Devil’s Number online slot review). 

Let’s start with the standard payouts. The Skull Bottles award between 90x and 360x your bet, while the Cauldron offers up to 180x. The Book pays from 36x to 150x your bet, and the Scrolls award up to 120x. 

But when upgraded, these symbols pay significantly more. The Skull Bottles pay up to 666x your bet, the Cauldron awards up to 360x, the Book offers a top prize of 300x, and the Scrolls pay up to 240x. 

The lower-paying playing card symbols cannot be upgraded. You can win up to 60x, 54x, 48x, 42x, and 36x your bet with the Ace, King, Queen, Jack, and 10 symbols, respectively. 


Red Tiger’s Devil’s Number slot UK has a 96.06% RTP and high volatility. You can bet between 0.20 and 40.00 per spin. 

How To Play Devil's Number

You may want to set up your bet before you play Devil’s Number slot. Use the ‘+’ or ‘-’ button next to the ‘stake’ meter in the bottom-left corner to increase or decrease the default wager, respectively. When you’re ready to start spinning, press the ‘spin’ button in the bottom-right corner. 

Match three or more symbols to win a cash prize and possibly upgrade them or remove them to claim a higher payout! You may also trigger a Free Spins feature for extra chances to win a prize — you can find out more about this later in our Devil’s Number slot machine review. 

Press ‘pays’ at the bottom of the screen to open the paytable, which covers all of the symbols and the bonuses. Click on ‘help’ to read detailed instructions on how to play the game.
