How to Play

King of Sun has a straightforward control scheme, so getting it set up and playing should be a breeze. If you want assistance in this 5x3 slot with 10 paylines, go to these brief instructions.

  1. The right side of the reels and screen is where the majority of the action happens. The three horizontal lines symbol serves as a convenient shortcut to the controls for the sound, bet amount, autoplay settings, game rules, paylines, and paytable information
  2. The “+” and “-” buttons on the button below the reels may also be used to adjust the bet size settings (€0.1–€100)
  3. Here you can also choose an auto-spin function
  4. The 3-line button allows you to control when or even if the gamble function is shown. We were grateful for this novel choice

King of Sun RTP and Volatility

6.7 

King of Sun has low volatility and the RTP is 95.22%.

Low volatility and a maximum win of 500 times the stake make the degree of risk appropriate. Though the hit frequency of 11.85% is fairly low, meaning that potentially only 1 spin out of every 10 will be a winning one, you can still get small wins more or less frequently.

Theme

In the realm of online casino games, Aztec culture has always been well-liked, and there have already been a ton of amazing titles in this genre. But this doesn't stop publishers from making fresh games that are influenced by the enigmatic Aztecs, and Swintt's King of Sun is just one of the numerous games that honor the legendary Aztec culture. Players are once more sent on a South American expedition in pursuit of Emperor Montezuma's lost treasures in this game.

King of Sun has excellent 3D graphics and smooth, precise movements. The audio is likewise spot-on; a spirited tribal soundtrack gives the scene a finishing touch. The 5x3 reels and 10 winlines are placed against a background of mountains and jungles when you first load the game.

We find a set of 10 identifiable pay symbols when we go over to the paytable. The bottom symbols are the traditional A–J card royals, while the premiums are 6 gleaming stones in various sizes, hues, and forms. Five-of-a-kind wins are valued between 10x and 50x the wager, and winning combinations must consist of 3 or more adjacent symbols starting from the leftmost reel.

There are also Expanding Wild and Scatters. Read about the features they trigger below in the review.

Bonus Rounds & Free Spins

7.5 

Expanding Wild

The Expanding Wild, one of the main features King of Sun offers, will only appear on reels 2, 3, and 4. If the symbol can act as a substitute and contribute to a winning combination, it grows and takes up all 3 spots on the reel. It cannot take the place of a Scatter sign.

Free Spins

Speaking of Scatters, they have the Feature logo, and if you obtain at least 3 of them, you'll trigger 12 free spins. The functionality can be activated again once it starts functioning. The Wild symbol is utilized for this function to enhance premium symbols (the lowest value one is upgraded to the next one in line). The game awards 1–3 Wilds on the reels with 1–5 additional spins.

King of Sun Demo Play

There is also a demo version of the King of Sun slot machine. It's wonderful news for those who are just getting started in the game. However, those who have been playing games for a long time would be relieved to hear the news. The trial version is the greatest method to learn the game and test your luck without having to invest real money.

Max Win

6 

The maximum win is 500x your bet.

King of Sun has a 5x3 field and a total of 10 paylines. With minimal volatility, your winnings will be not big but frequent. Especially, the returns of up to 500x are not stunning either. Another potential concern is that the RTP only goes up to 95.22% which doesn’t promise industry-average returns.

Overall Rating

7.3

It isn't the greatest slot machine, at least not as a low-volatility choice that is meant to frequently provide winnings, no matter how tiny. Even if the aesthetics are outdated, the functions are still enjoyable, especially if you can trigger the feature spins.

The slot is not about Ra or ancient Egypt, as one would think coz of the title. It’s about Aztec civilization.
Like many other Swinnt slots, it has a pretty simplistic gameplay and nice design. The slot’s heart of the matter is free spins with symbols upgrade. There are also expanding wilds to make the base game more enjoyable.
The math is a bit extreme for the slot with the max win of x500. Even 30 empty spins in a row are common thing. But the game can also award hits once in a while.
