Sinful 7s - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction

Take a trip down to the furnaces of hell with Sinful 7s from Blueprint Gaming. This title is played on a five-reel grid with three rows and ten fixed paylines. Spin the reels to match traditional fruit-based symbols, including cherries, plums and watermelons, alongside theme-specific symbols such as a trident and wild devil.

Features in Sinful 7s include an innovative gamble option whereby it is possible to change the odds of winning. Of course, changing the odds will also change the potential returns, with less likely outcomes yielding more winnings. 

In this Sinful 7s slot review, we will take a look at all aspects of this online slot title including the gameplay, graphics and payout. This will give you all the information you need to play this game.

Theme, graphics and soundtrack

The flame-licked reels have great look about them in this title, with embers continually rising in the background to give an illusion of fire. This overall look to the background has a high-quality feel.

The reels pale in comparison with the background, with rather standard-looking fruit-based symbols mixing with the specially designed symbols for this title. These are rendered well enough but lack the outstanding quality of the background.

When the reels are not in motion, the background sound effects are the crackling of the fire we see in the background. Unfortunately, this is trampled over by the music that plays as the reels spin, which is loud and rather obnoxious. 

Sinful 7s RTP and variance

The RTP of Sinful 7s is 95.36 per cent, which is comfortably below the average rate for online slots. The average RTP for an online slot is around 96 per cent.

Sinful 7s has medium to high variance, with a balance between the smaller payouts that are more likely to be achieved and the higher wins available. Higher-level wins are not achieved often when playing, so these must not be relied upon.

Wild

The wild devil symbol provides an enhanced payout if five are matched on a payline, which is a fantastic 500x the total bet. The wild also substitutes for all other symbols apart from the scatter.

Free spins

The scatter trident symbol triggers the free spins when three or more appear on any reel location. Land three scatters to trigger 12 free spins, with five scatters awarding a fantastic 24 free spins. During the free spins, all 7 symbols are upgraded to the highest-paying 7 symbol on the payline.

Gamble

If you win on a spin, you can be taken to the bonus wheel gamble spin round. Spin the wheel and if the arrow finishes on green, your winnings are increased; however, landing on red sees your winnings vanish. Changing the size of the green sector changes the potential returns.
