Play Devil’s Number Slot for Free & Review

Devil’s Number is a 5 reel, 4 row, 30 payline slot from Red Tiger Gaming. The highlight here is the free spins round where the removal of lower value and the upgrade of higher value symbols can really boost your winning chances. Play on your PC, tablet or mobile device from between 20p and £40 per spin.

The design here is comic book style and is nicely done. The setting is a creepy old library. Joining the lower value A to 10 royal values are scrolls, a book of spells and a cauldron. Top of the payers is the bottle of potion with the skull stopper which delivers 3, 6 or 12 times your stake if you land 3, 4 or 5 on 1 of the game’s 20 paylines. There are 2 special extras that can boost your base game wins.

Upgrade feature - this can trigger on any spin made up of 1 of the higher value scroll, book, cauldron or potion bottle symbols. The payout receives a boost. For example, the potion bottle pays 6, 12 or 22.2 times your stake rather than 3, 6 or 12 times your stake.

Remove feature - land a win made up of 1 of the lower value A to 10 symbols for the chance to trigger this extra. The winning symbols are removed and a cascade follows, giving you another chance to land a winning combination.

Devil’s Number also comes with a Free Spins feature – this is triggered by landing 3 of the 9 symbol on the middle 3 reels on the same spin. Then then turn upside down to reveal 666! You’ll then receive 12 free spins. Both the Upgrade and Remove features are in play throughout the feature – if you get a win from a low value symbol, they are removed permanently though. Every win with a high value symbol upgrades the symbol permanently too. Re-triggers are possible too.

The theme here won’t be to everyone’s tastes. If you don’t mind that, then you should find enough to like here to make Devil’s Number worth a look. The comic books visuals are well crafted, backed by a heavy metal soundtrack. The features aren’t bad either, especially the Free Spins feature where the removed symbols and upgraded payouts can deliver some pretty impressive action.

Medium variance, you can win 2,500 times your stake on every spin or free spins with the upgraded payouts - if you’ve liked the other slots in the Red Tiger Gaming catalogue, expect more of the same from Devil’s Number. If you like the theme, NetEnt’s Devil’s Delight or Play ‘N Go’s House of Doom are recommended.
