Sinful 7’s Game Mechanics

The Sinful 7’s game has a classic layout with five reels and three rows. There are ten winning ways in the game. Among symbols, you’ll find both traditional fruit and demonized bells and sevens. The sounds are hell-droll, and the game has funny animation. When you win, be ready for an authentic sound of coins being paid out, one after another.

The feature pack is also interesting in this video slot. But before describing the game’s extras, let’s observe its winning potential.

Random Number Generator

What are your chances of grabbing a Sinful 7’s big win? First, let’s say winnings are possible since the slot is created by a reputable game studio with several licenses and all the software certified. An approved RNG mechanism ensures the game’s fairness. So, gamblers can play it and expect 100% random outcomes.

Return to Player (RTP)

The slot’s RTP is 94.56%. It could be higher, but it is quite standard for the provider. We know even more hellish variants of slots with an RTP of below 80%.


The volatility here is medium. This means you are going to play online Sinful 7’s with a chance of winning a diabolically luring prize. Although it may fall into your hands faster than in a high volatility slot, do not expect to get it on your first entry to the hell room.

Maximum Winning

The Sinful 7’s jackpot is fixed – this is a prize of 250,000 credits. Alternatively, the maximum winning in the game may reach the equivalent of 50,000x your stake. This could be a colossal winning potential in the game. However, its betting options range from 0.10 to 2.00 credits. So, the slot is not the best choice for a high roller.

Sinful 7’s Features and How They Work

Think classic slot machines are all the same? Try this new Blueprint release to change your mind. Its gameplay is hot as hell, and it won’t let you get bored. The key features include the following:

  • Wild & Scatter;
  • 7’s Upgraded Symbol;
  • Spin Boost;
  • Free Spins;
  • Gamble.

So, the Sinful 7’s slot for real money represents a fusion of a good old fruit machine with a modern feature set.

Special Symbols

The Imp is the Wild symbol. It will help you to build more winning combos since it replaces anything besides its own Trident. This is the Scatter, and you will need them to cut your way through the fire to the Free Spins round.

Spin Boost

It’s hard to show patience in hell, but you can avoid those ordeals of waiting till you have enough Scatters on the reels to unlock the bonus game. For this purpose, there’s the Spin Boost feature in the Sinful 7’s game, as well as the button with the same name – you’ll see it on the left of your screen.

Sinful 7 Spin

Just press Spin Boost, agree to stake 5 credits, and your Free Spin session will be launched. That’s hell-simple!

Free Spins

Naturally, you need to collect 3+ Scatters to unlock the bonus game. The number of free spins is defined by the number of Scatters:

Scatters Free Spins Awarded
3 12
4 18
5 24

Sinful 7 Bonus

As you play the bonus session, be ready for your Sevens to get upgraded. That is, a one-Seven symbol may turn into a two- or three-Sevens symbol, with a sure boost for your winnings.


There’s also the Gamble feature in the Sinful 7’s Blueprint slot game. You need to press the Gamble button on the right to launch the feature. Ensure you see the Gamble ON icon on your screen and start spinning. As soon as you land a winning combo, the feature will be activated.
