You can play this online slot here at Slingo Casino.

This slot has a classic playing field with 5 reels, 3 rows, and 10 winlines.

There are 8 pay symbols in the Sinful 7s slot, and they are split evenly between low pays and high pays. For the former, there are fruit symbols with cherries, oranges, plums, and melons. They all pay the same, too, with 10x payout on offer for full combinations. Then, there are single sevens, double sevens, triple sevens, and bells. Bells are worth the most, and you’ll get 100x your bet for a five-of-a-kind combination. As for the sevens, you can actually mix them together for a smaller payout.

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.

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.

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.
