Blueprint are one of those studios that keep things ticking without making a great deal of fuss, and we’re certainly happy that they are keeping us busy. With Sinful 7s, we’re getting a pretty interesting package, at least at first glance. Does it really hold up to scrutiny? Well, we’ll take a look at all its ins and outs over the following paragraphs, and we’d like to start by saying that this slot has a classic playing field with5 reels, 3 rows and 10 winlines.
Thematically, Sinful 7s presents a devilish take on the classic fruit theme, and it worksrather well. The symbol designs are pretty colorful, for one, though it’s worth noting that the game is a bit short on animations, and that there’s not much to be said about the audio side of things. Still, it’s a pleasant experience overall.
The math model of Sinful 7s has amedium-highvolatility level, but we don’t have any official info about its actual jackpot. You can jump in for many different stakes, then, as the betting range starts at just£0.10and goes all the way up to£100per spin. Unfortunately, it seems that the game’s default theoretical RTP is only95.36%, which is rather subpar.
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 areworth 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.
In terms of specials, there areDevil Wilds and Trident Scatters. Devil Wilds can substitute for other symbols, and they are also valuable on their own. In fact, if you manage to line up 5 Devil Wilds on one of the winlines, you’ll get a huge 500x payout!
Land 3, 4, or 5 Trident Scatters to activatethe Free Spins featurewith 12, 18, or 24 free spins, respectively. Retriggers are possible, too, and the main kicker is that all sevens symbols that are part of a winning combinationget automatically upgradedto the highest-paying sevens symbol on a winning line.
You can also opt in and usethe Spin Boost option, which gives you spins with the same upgrades as during free spins. Each such spin will set you back by 5x your usual stake, however.
Players can then also try to boost their wins withthe Gamble feature, though that doesn’t really add anything to the gameplay as such.
Well, what can we say? Sinful 7s is a pretty compact package with both its pluses and its minuses. We like its visuals and the idea with upgradable symbols, but it does feel slightly lacking overall, and the math model that powers it allisn’t particularly good, either.
