The visuals in 7 Sins have a historical feel - joining the lower value heart, diamond, club and spade symbols are 7 women, each of whom represents 1 of the 7 deadly sins. For the virtuous amongst you, they are Pride, Greed, Lust, Envy, Gluttony, Wrath and Sloth.
They are joined by 2 wild symbols - the Lucky 7 is a standard wild, substituting for all other symbols apart from the scatter. This one can only hit on the odd numbered reels (i.e. 1, 3 and 5).
The Double Lucky 7 is the second wild - appearing on reels 2 and 4 only, it also replaces everything with the exception of the scatter. As its name suggests, the Double Lucky 7 counts as 2 symbols. Land it on both reels on the same spin alongside a trio of matching symbols and you can land a 7-symbol combination.
7 Sins also comes with a Free Spins feature - land 3 of the Pandora's Box symbol (which is the scatter) on reels 1, 3 and 5 to trigger the feature. You'll then be awarded 7 free spins. If you manage to get 2 Pandora’s Box symbols, you will trigger the Second Chance feature which gives you the chance to trigger the Free Spins feature – simply pick 1 of 7 figures on the screen to find the 3rd scatter or win an instant cash prize.
During each free spin, 1 of the 7 sin symbols will appear as a stacked symbol on the middle reel with the other 4 reels spinning. A multiplier starts at 1x and increases by 1 on each free spin. By the time you reach your final freebie, you'll be playing with a 7x multiplier.
As you'd expect given the theme, 7 Sins is a feisty, volatile slot game. The variance here is very high so be careful if you're playing with a limited bankroll. Saying that, you can win up to 1,580 times your stake on each spin!
With the potential for 7-of-a-kind wins and a Free Spins feature with stacked symbols and an increasing multiplier, there's plenty of temptation on offer from 7 Sins. Get lucky in that bonus feature and this naughty little offering can be very nice indeed. If you like the theme, I recommend you play the classic Devil’s Delight from Net Entertainment.
