The game itself looks quite classy- it involves different gems as well as the Harlequin which is a wild symbol. The interesting thing about the harlequin is the fact that it can land stacked- which means you can get better base game wins with a stacked wild. But also the fact that the Wild Harlequin is also a scatter- once you land 3 wild harlequins, you'll trigger the free spins round. I have to say that I quite enjoy the base game as you can get good winning combinations due to the stacked wilds, and also once you trigger the bonus round, you might get a good win with the 3 stacked wilds before you enter the bonus, which is great.
The bonus round itself is also quite fascinating. You get 10 free spins and on each reel there's a meter- once a wild symbol lands on that reel, it will fill the meter. And once the meter is filled, you'll get extra spins and the multiplier will increase. I've managed to fill several of the meters and get 6 or even 8 extra spins with a higher wild multiplier. And that's when you can get really decent hits. I've had a few wins over 100x bet and my best win was from free spins, when I had an overall of 18 free spins and it paid 300x bet. Also from my experience, the game is medium volatile and the free spins feature comes up quite often- and while it usually pays around 40x bet, it can easily keep your balance steady on the base game due to the stacked wilds.
Overall I've been quite pleased with this game. I initially tried it being quite skeptical, since it's a 10 payline slot and my experience with QuickSpin games hasn't been extremely rewarding. However, I tend to play this game when my balance is running low and it has boosted my balance many times. It's a simple game when it comes to graphics yet the features are quite good. Definitely one of my recent favorites from QuickSpin.
