The King offers quite familiar mechanics and patterns with a 5x3 playing field and adjusted (1-10) number of betways. It pays from the far-left reel in the left to right direction. The winning line must include a similar symbol in no less than 3 adjacent reels.

Two additional features of the slot are free spins and the Gamble round.

The King RTP and Volatility

The King is a high-variance slot with an RTP of 96.07%.
The slot is highly volatile, as can be seen from its paytable. The slot tends to give relatively small wins and then surprise you with a big hit. The hitting rate depends on the number of active lines – more betways, more wins. However, the number of active paylines and hit frequency doesn’t influence the slot’s RTP, which is average, but for the Gamble Feature where the RTP rate is just 84%.



The King

The King slot takes you to times of kings, knights, and magnificent castles. Look at the background of a powerful Middle Age European city to feel the vibe. The slot’s graphics are cartoonish but detailed. There are small animations and epic sound parts that follow every winning line. Most of the gaming process is the FS round.

A standard package of 13 symbols is present in the game. 11 elements are regular symbols (cards symbols, a shield, a helmet, a treasure, a knight, and an archer), and two others are special ones.

The wild symbol not only substitutes regulars on reels but is also the highest-paid element in the game that forms its own winning lines.

The Scatter symbol multiplies overall stake and triggers free spins (3+ scatters). It pays regardless of its position on the reels.

About Endorphina

Endorphina is a popular slot developer from the Czech Republic. The company was founded in 2012, obtained an MGA license in 2017, and released its 100th game in 2021. As you can see, it’s a quite successful and proactive provider.

Endorphina gained much attention in 2016-18 by releasing controversial slots like Taboo, Maori, Twerk, and Geisha. Funnily enough, those mentioned games are not the most popular ones. Slots of the classic genre are the biggest attractors in the company’s portfolio, with Sparkling Fresh, Lucky Streak, and Hit Slot being the most successful ones.

Bonus Rounds & Free Spins


In The King slot, you can gamble your winnings, trigger free spins and purchase a bonus.


After each successful spin, you can try to increase your winnings with the gamble option. Press the red card button on the left side of the control panel to start the round.

At the start of the gamble round, you will see 5 cards. The 1st card is the dealer’s one, and it’s open; the following 4 cards are facedown, and you must pick 1 of them. If your hand beats the dealer, your winnings will be doubled.

You can play up to 10 rounds during a single risk session.

Your chances of beating the dealer’s hand depending on the dealer’s card. For example, if the dealer got 2, the probability of beating him is 162%, but if he got an A, the chance is only 42%.
The King Slot - Gamble Feature

Free Spins

Land 3 or more Scatter symbols to trigger 15 free spins with an 3x multiplier. Getting another 3+ scatters in a view retriggers the round.

Bonus Pop

One more special feature of The King slot is the Bonus Pop, which allows to launch the Free Games feature after the purchase. Although the cost of Bonus Pop depends on the stake you have set, in general it will cost you 102x.

The King Demo Play

Every website visitor can play The King slot for free, as we added its demo version. We think free play is the best way to learn the game’s mechanics, payouts, and features.

Feel free to choose any bet size, as even if you lose the whole balance, you can restart the slot to get a new deposit. Of course, these funds are not real, and you cannot withdraw any winnings from the demo play. If you want to spin the slot for real money, consider visiting an online casino.

Max Win

The maximum theoretical win in the slot is 9,000x.

The King can pay as much as 9,000 times more than your initial bet. What’s more shocking is that you can catch such a massive win from a simple five-of-a-kind line of wilds. The only additional condition is that you must land such a combination during free spins.

Free Spins are more suitable for bigger hits due to the 3x multiplier that applies to every winning line.
