King of Slots Slot Overview

Casinos are full of slots that fill their reels with pictures of fruit. They don’t all have the nerve to call themselves “King of Slots”. NetEnt is certainly leaning into the classics with this 5-reel, 20 payline design, but there are aspects of the fruit machine theme that don’t fit with the tradition. There’s also a free spins bonus, complete with a win multiplier of x3. Read our King of Slots slot overview, then take a moment to consider whether you need timeout or self-exclusion functions activated before you spin.

Coming into Land

If we were to tell you that a video slot was set by the ocean with blue water and towering cliffs, you might think we were describing a pirate or fishing theme. King of Slots is a classic game, but that doesn’t change the fact that it gives you a bird’s-eye view of the sea and the rocks and greenery marking its edge. Later, there’s a dark room with curtains and a checked floor that is more suited for a palace.

King of Fruit

Let’s talk about how King of Slots takes a royal look at that most traditional theme: the fruit machine. We have the cherries, lemons and watermelons, but rather than slightly garish retro graphics or highly detailed realism, they’re depicted like jewellery, gleaming as carefully crafted precious stones. They sit alongside other symbols of wealth and royalty, namely a crown at the top of the paytable and actual gems of different colours as the scatter symbol and wild symbol. When the paytable is open, you’ll also see the king himself as a less-than-regal cartoon.

King of Slots RTP & Variance

The RTP of the King of Slots slot is 97%. The variance is low.

How to Play King of Slots

Be cautious with real-money slots:

1. You’re not a king with a bottomless treasury, so it’s best to make a budget to guide you before you start wagering.


2. There’s a max bet button under the reels, but if you want to be a little more restrained, adjust the level of your stake using the plus and minus symbols on the right. You can go as low as 25p.


3. Don’t forget to take a trip to the info button. This is where the rules are explained, along with the breakdown of symbols and their values, and the mechanics of the bonuses.


4. Make one final adjustment of any remaining settings, then spin.


5. Watch the reels turn, and be prepared in case they don’t go your way. Review your budget and limits, then decide whether it’s worth spinning again or if you should pause.


6. Have fun and be responsible.

How to Win at King of Slots

Once you’ve hit spin, all 5 reels in King of Slots turn. Where they stop is random, but if at least 3 matching symbols cover 1 of the 20 designated paylines travelling adjacent and consecutive and starting on the left, that’s enough to score you a payout. You can view the values of all possible combinations of winning symbols in the paytable.

King of Slots Top Win

• There are only 4 paying symbols, which is low compared to the 7 to 10 you find in most modern slots.


• Like you’d expect, you can score with 3 or 4 matches, but a max win needs a combination of 5.


• The least valuable of these are the cherries. Find 5 of them and earn 200.


• It’s 250, then 300 for the lemon and watermelon before you reach the crown for 1000.


• The wild symbol and scatter symbol don’t pay. They’re there for their special functions, as a substitute and a bonus trigger respectively.

King of Slots Bonuses

The King of Slots bonus features are focused on its free spins round, a popular addition to the reels. You trigger it if the scatter symbol lands enough times in the base game. If you find winning symbols during the bonus, you can also boost your payout with a win multiplier. There’s one other feature: sticky wins.

Free Spins

The number of spins in this round depends on how many base game scatters you successfully land on 1 turn:

• 5 scatters = 10 free spins


• 6 scatters = 15 free spins


• 7 scatters = 20 free spins


• 8 scatters = 25 free spins


• 9-15 scatters = 30 free spins

During free spins, a multiplier of x3 applies to every set of winning symbols, meaning your total win could be tripled if you find enough matching symbols.

Sticky Wins

If you’re wondering why 3 scatter symbols isn’t enough to trigger free spins, as it would be in most slots, 3 or more scatters trigger sticky wins. Winning symbols remain in place while the rest of the reels spin again. New matching symbols can join the existing combination to boost the total win. The feature continues until a spin sees no new winning symbols being added.

King of Slots Overview - Summary

We call King of Slots a classic fruit machine, and in some ways it is, but some aspects of it seem more modern or even unusual. Other NetEnt slots may come with free spins or multipliers as these are popular types of features, but here they follow their own distinct mechanics. Sticky wins are rarer, while the gem style of the symbols and the ocean background could seem refreshing compared to more retro versions of the theme.
