About King of Slots Slots

Net Entertainment decided to go big or go home when they named their King of Slots game. It certainly sounds impressive, but does the slot live up to its title? Yes and no. Yes, because there is great value to be had when you catch those Sticky Wins. No, because the slot doesn’t look very kingly at all. Whilst the graphics are crisp and neat, they lack imagination and are a little boring. But you’ll want to take this one for a spin anyway.

Game in Action

Plenty of slot developers return to the trialled and tested when coming up with new slots. Net Entertainment fell back on the Jack Hammer engine when they created their King of Slots game. And we know how popular Jack Hammer is. Using features that have proven themselves in new slots is not a problem at all, but NetEnt could have been a little bit more creative in the execution.

King of Slots gives us a more classic theme with jewel-encrusted fruits, crowns, a diamond Scatter and some golden card symbols. The design is simple and understated and there’s nothing wrong with that, but it’s also somewhat boring. The cartoonish king doesn’t quite fit into the design either. But don’t let that bother you, because you are here for those Sticky Wins and the Free Spin Bonus, which make this slot surprisingly worthwhile.


As soon as you get three or more matching symbols on the reels, they will stick around for a free re-spin. If additional matching symbols or additional winning combinations show up on the re-spin, they’ll stick around as well. As long as you can add to the existing winning combinations, the re-spins will continue. Until, of course, the screen is either full of matching symbols or winning combinations or you came up empty on a re-spin and your winnings are paid out.

With a little luck you can end up with 50 to 100 times your stakes and it doesn’t even require a high paying symbol to become sticky in order to reap in some rewards.

The main bonus feature is of course the Free Spins. You’ll need at least 5 Scatters in order to trigger the Free Spin Bonus. That might seem a lot, but if you get three and they become sticky, you’ll easily collect more Scatters on the re-spins.

If you get 5 Scatters, you’ll be given 10 free spins. For 6 Scatters you’ll get 15 spins, whilst 7 will award you 20 spins. It needs 8 Scatters to receive 25 spins and with 9 or more Scatters you’ll get 30 free spins.

Of course, the Sticky Wins will stick around for the Free Spins as well and on top of that a 3x multiplier is applied on all wins. That can make the Free Spin Bonus extremely lucrative, resulting in opportunities to win 3,000 times your stake.

You can even re-trigger the Free Spin Bonus, if you manage to collect at least 5 more Scatters.

Other Slot Machines You Might Enjoy


King of Slots is quite a volatile one, which means winnings come often and sometimes they are really quite decent, if not amazing. The Free Spin Bonus is not that easy to come by, what we managed it within 100 spins. Since you’ll be getting plenty of Sticky Wins and free re-spins during the base game alone, you won’t be getting bored anytime soon.

Alas, we still believe NetEnt could have delivered a graphically more interesting slot. You know well enough what they are capable of. Then again, you do need slots that simply pay, and this one certainly does. Not all the online slots are about their pretty looks or amazing gameplay. Sometimes you just want to feel like a king when those wins keep coming.
