King of Slots

If you're a big fan of NetEnt's Jack Hammer and Jack Hammer 2 slot games, you're invited to the throne room where the King of Slots is waiting to receive you.

King of Slots uses the same thrilling Sticky Wins Feature as these two other titles, and as anyone who's seen the feature in action knows, Sticky Wins make it possible to create enormous wins via a process of frozen symbols and re-spins.

But, there's even more to love about this royalty-inspired online slot, and that's the Free Spins Bonus which can award up to thirty free games and the potential to win more while playing through your free spins. Plus, you can try and conquer the game's top payout of 750,000 coins with a bet-per-spin of 25p and upwards.

More about the Software Provider

NetEnt is an instantly recognisable name in the online casino industry, and one reason for its fame is that its software is used to power scores of online and mobile casinos throughout Europe and beyond.

However, even casino sites that run on other types of software often stock NetEnt slot games and casino games, ranging from NetEnt Live (a suite of live dealer games that includes Three Card Poker, Roulette, Blackjack, and Baccarat) and video slot games like Gonzo's Quest, Guns N' Roses, Jack Hammer, and Planet of the Apes to progressive jackpot slot games such as Mega Fortune, Hall of Gods, Arabian Nights, and Mega Fortune Dreams.

Appearance and Sound Effects

At the moment that you load the game, you'll find yourself face-to-face with the King of Slots – a merry, old monarch who stands at the side of the screen wiggling his eyebrow and smiling at you expectantly.

The throne room provides the setting, although it's very dimly-lit so as to put the emphasis on the reels where you'll find a mixture of gold-plated classic slot symbols (such as lemons, watermelons, cherries) and royal treasures such as sapphires, amethysts, gem-encrusted crowns, plus five low-value playing card symbols.

The music is a modern jazz number that is fast-paced enough to keep the game ticking along nicely.

Bonuses and Special Features

Every time you create a winning combination or land three or more scatter symbols on the screen while playing King of Slots, the Sticky Win Feature is initiated. It holds the winning symbols in place while re-spinning all of the other reels to give you another chance to improve the existing win or create more winning combos. And, as long as new or enhanced wins are formed, the re-spins process continues.

The wild symbol (which is the sapphire) can also help you gain prizes by substituting for all symbols except scatters.

The scatter in King of Slots is the glittering amethyst symbol, and as the Sticky Win Feature can help you land a lot more scatters than a regular spin, there's the potential to win up to thirty free spins when five to fifteen scatter symbols appear anywhere in view. All wins in the Free Spins Bonus are tripled.


King of Slots Big Bang uses five reels, three rows of symbols, and twenty-five fixed paylines, and boasts a very high RTP (Return to Player Rate) of 97.00%. The game lets you create winning combos using matching symbols in succession from left to right, starting from Reel 1.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.

Our Verdict

You'll feel like royalty when you play King of Slots as you create wins using regal symbols like the crown, amethysts, and sapphires. But, it's the game's main special feature that can really help you to feel like king of the castle, as the Sticky Wins not only make it possible to create increasingly high-value winning combinations with consecutive spins, but also give you the potential to earn up to thirty free spins to use in the bonus game where all wins are tripled.
