The Lucky 7 is probably the most common symbol in online slots. It appears in all types of games, from classic three-reel to most advanced five-reel slots. However, Blueprint Gaming found another way to include this popular symbol - by adding it with a cute-looking devil. In the Sinful 7’s slot, you can win up to an impressive 50,000x the bet from the free spins round. Discover more in my in-depth Sinful 7’s Slot Review below.

About Sinful 7’s Slot

The Sinful 7’s slot plays on a classic set with 5 reels, 3 rows, and 10 paylines. This reel layout may sound basic, but wait until you see how powerful this game can be! It accepts a variety of bets to suit every player’s preferences, ranging from £0.10 to £100 per spin.

To win in the Sinful 7’s slot, you have to land 3 or more matching symbols across a payline, from left to right. I said that the game is powerful, right? That’s because it can pay up to an impressive 50,000x per spin, which combined with the maximum bet could turn into a big payout!

The biggest wins in the Sinful 7s slot are achievable through the bonus features. Blueprint Gaming packed the game with a Free Spins bonus with symbol upgrades. I’ve covered more about this feature below.

Design, Symbols and Graphics

If I need to explain the design of the Sinful 7’s slot in a single sentence, I would say that it’s a devilish take on the fruit theme. There are flames in the background, which are perfectly complemented by the fiery sound effects. Even if the design is pretty basic, it’s of the highest quality and provides smooth gameplay.

On the reels, you’ll encounter low-paying fruit symbols: cherries, oranges, plums and melons. Then, there are the high-paying symbols, designed as single sevens, double sevens, triple sevens, and bells. The bell is the top-paying symbol, awarding up to 100x the bet for a 5-of-a-kind combination.

When it comes to the special symbols, there are Devil Wilds and Trident Scatters. The wild symbol substitutes for all regular symbols and pays up to 500x the stake for 5 on a payline. On the other hand, the scatter symbol triggers the Free Spins bonus which I’ll explain below.

RTP, Variance and Payouts for Sinful 7’s Slot

The Sinful 7’s slot is made with medium-high volatility, which entails scarce, yet highly valuable rewards during the gameplay. Combined with a maximum win potential of 50,000x the stake, the winning outcomes here can be quite lucrative.

The Sinful 7’s slot RTP has been set to 95.35%, which is slightly below the industry average.

Gameplay and Features on Sinful 7’s Slot

Unlike other Blueprint Gaming releases, the Sinful 7’s slot doesn’t have many bonus features to offer. However, sometimes less is more, which is the case in this slot’s gameplay. Namely, during the free spins bonus, you can win a tremendous prize of 50,000x the stake!

Free Spins Feature

To trigger the Free Spins feature in the Sinful 7’s slot, you need to land at least 3 scatter symbols on the same spin. Landing 3, 4 or 5 scatters will give you 12, 18 or 24 free spins, respectively. 

What’s great about this round is that all 7s symbols that are part of a winning combination will be automatically upgraded to the highest-paying 7s on a winning payline.

Furthermore, you can use the Spin Boost option in the base game which will give you the same symbol upgrades as during the free spins. However, it’ll cost you an additional 5x your stake.

The Free Spins feature can be retriggered by landing an additional 3 or more scatters during the round.

Other Blueprint Gaming Slots

Blueprint Gaming has produced numerous top-performing slots on the market, establishing itself as one of the leading providers in the industry. So, if you want to try other Blueprint Gaming slots, I’ll recommend you to check out these releases: Temple of Riches, Bison Rising Megaways, and Copped the Lot Diamond Heist.

Our Verdict

The Sinful 7’s slot doesn’t offer much in terms of bonus features, but it does offer high payouts which make up for the feature absence. The symbol upgrades are an excellent addition to the free spins bonus, and that’s the main action in this slot’s gameplay. Everything else is basic, including the design. I was also a little disappointed by the game’s below-average RTP.
