4 of a King Slot Review

The 4 of a King slots game can be found at casinos offering Endorphina software. Endorphina are one of the newer casino software providers on the market but they have managed to gain distribution with some of the largest casino networks currently active within the market. As a standard Endorphina do publish the RTP/House Edge information for their slots games within the game help file or paytables. As a software provider not licensed in the UK, and as such not required to publish this information, this is a significantly player friendly practice. As such we can state that the 4 of a King House Edge is 4.00%.

4 of a King a 5 reel slots game and each reel is 3 symbols high. The game uses 10 paylines and you can bet up to 10 coins per payline.

Special Symbols

Wild – The “Casino Chip” is the Wild symbol, replacing all symbols. It also expands to the adjacent reels every time it appears and can cover up to 3 reels in wilds.

“The Couple” – The most valuable symbol is “The Couple”. 3 of “The Couple” symbols will award you 20 coins, 4 will award you 100 coins and 5 will award you with 1000 coins.

Bonus Features

Take Risk – Whilst you might not necessarily class this as a bonus feature, it does play a significant role in the gaming experience. With every win you get the chance to try and double your win by trying your luck in a game of “Play Your Cards Right” with the game’s dealer. If you can flip over a card that is higher than the one the dealer is showing you will double your win. Flip a card that is lower than the dealer’s and you lose the lot. This round continues until you either choose to stop gambling or you lose out to the dealer. In the result of a tie, no one wins.


4 of a King is as simple a slots game as you are likely to find. So much so that there is very little going on here for us to actually review. The game is set in an old-fashioned looking casino, has few symbols to discuss and only has one real bonus feature to mention. There are wilds, no free spins and the bonus that we do have is no more than some expanding wilds, which is normally only an additional feature for games that choose to include it. It is unlikely that this game is going to hold the attention for long and with an equally uninspiring house edge of 4% I’m seriously struggling to find anything here to recommend. The best that can be said for 4 of a King is that there are worse games out there, offering less entertainment that don’t look as good. However, I’d be lying if I said there were very many.
