4 of a King Game Overview

4 of a King slot machine by Endorphina does not contain the modernistic graphics or advanced sounds that you may expect from a contemporary video slot, nor does it has some extra bonus boosts. However, it is helpful in satisfying your spinning cravings.

The game has 5 reels, with 3 rows and 10 adjustable paylines. The game requires a constant passion because to win the maximum payouts, you need to continue making the winning combinations on the active paylines. There is no bonus round, apart from that you will get the gamble round that you are free to play as per your choice.

Symbols and Paytable

96% 4 of a King RTP suggests that it’s an attractive game for a large number of online players who like to go for the simplistic versions and are not looking for maximum bonus rounds. Overall, this game is best in terms of high and low paying symbols categorisation .

A card featuring both lady and a man pays the highest for the combination of five, while cards with a single man and a single lady pay the second-highest winning combinations from the game. The lowest paying are the coloured cards. There is no scatter icon, however, there is a wild symbol that contributes to accelerating your winning rate.

Paytable of 4 of a King Slot
  • 96% RTP
  • RNG Passed
  • Reliable Developer
  • Wild Bonus Symbol
  • Gamble Round
  • Convenient Interface
  • No Bonus Round
  • No Free Spins

There is no progressive jackpot for 4 of a King slot, but you can win as much as 10,000x times of your total bet by making the best combination for high paying value icons. The reason the 4 of a King slot RTP stands at the best rate because the game offers flexible betting range and it’s all the icons pay generously. Even the low paying symbols will get you a winning combination of 1,000 times of your net bet, which is pretty cool.

So, we would recommend that don’t judge this game with its icons and graphics but weigh the pros and cons, then decide if it is worth playing or not.

Special Feature

As discussed earlier in the 4 of a King slot review that this game does not contains extra bonus symbols or the bonus rounds. Rather you have only got one special symbol, that is ‘Wild Card’ which behaves a wild to dominate over all the icons by replacing them. Moreover, whenever it appears at a certain position, it expands over to the adjacent positions.

However, the game contains a special ‘Risk Game (Gamble), that provides you with an opportunity to increase your winnings as much as up to 10 times. In this round, all you have to do is to choose from a face-down card to beat the dealer’s card.

Well, the gamble round of the game is quite interesting, as you need to make the wild guesses, and more often it does work for the players where they get back to their main game with their balance inflated with the handsome prize by winning the gamble round.

As per the game’s statistics, the average return to player from this round is 84%, but you can see that in every round your chances to win the game might change.

Mobile Version

4 of a King gameplay is available in the mobile version too, because in the year 2020 every player wants easy access to their favourite game without sitting in front of their PC. The mobile version of the game is slightly different from that of the desktop as you will find the spin and turbo button in the hybrid form next to the fifth reel.

With the $ icon at the bottom right side of the reels you can re-adjust the coin value, bet size and paylines, as in the desktop mode all these buttons are present at the base of reels. Here is the best 4 of a King mobile casino:

100% up to £200 + 11 Spins

  • Great Payouts
  • Big Game Variety
