95.36 per cent


Low value symbols are represented by different fruits with cherries, oranges, plums and watermelons. If the right amount of winning combinations land on a single spin then these symbols can offer between x0.5 and x10 the player’s stake. 

Medium value symbols come in the form of different levels of lucky sevens with one seven, a pair of sevens and a bunch of three sevens. These symbols can offer between x1 and x25 the player’s stake, depending on the amount of matching combinations that land in one go. 

These sevens can also provide payouts for when they are not matching, offering between x0.5 and x5.

The highest-paying symbol is a bell, offering between x5 and x100 the player’s preferred stake. 

Devil wilds are also available, substituting for all symbols other than the trident scatter. These wilds can offer a payout between x10 and x500, depending on the amount of wilds that land on a winning payline. 

Finally, trident scatters can drop into play, triggering a free spins feature if three or more land on the reels at once. 


With the free spins feature, landing three, four or five scatters will award players with 12, 18 or 24 free turns. 

Any lucky sevens that appear on a winning payline will automatically turn into the highest-paying sevens symbol, the bunch of three sevens, to increase the win potential. 

If an additional three, four or five scatters land on the reels during the free spins, then an extra 12, 18 or 24 free turns will be provided. 

After a payout is provided, players can choose to gamble for a higher cash prize. To do this, players must spin a wheel and land the marker on a green section of the wheel. 

Players can change the specifications of the wheel to offer more winnings on a successful gamble, however this will reduce the amount of green space on the wheel. This gamble can also be activated when awarded free spins in a bid to gain more free turns. 

Players can also activate the spin boost for the price of an increased bet in order to make all sevens turn into the three sevens symbol when on a winning payline.


Jo Purvis, Director of Key Accounts and Marketing UK at Blueprint Gaming, commented: “Sinners are winners in our latest devilishly fun game. The mix of free spin potential and the fast-paced, fiery reels are a wicked place to be, making Sinful 7’s a red-hot place to enjoy some slot entertainment this Halloween.”
