The King Review


The King slot by Endorphina Software is a title that will lead you back in time into the medieval world. The folks at Endorphina never disappoint – there are always interesting graphics and exciting gameplay, and this slot is no exception. The game has an RTP (return-to-player) of 96% and five reels that are set on a backdrop of a castle wall.

We enjoyed that the game had as little as 0.01 credit on a single pay line, and with volatility set at a medium level, we were satisfied with the amount of wins we got. In the game, there are standard playing card symbols, but to win big, you need to line up the armour and treasure symbols. Read on to find out what else we discovered about this slot.

Bonus features

Game Symbols

The wild symbol is a crown, and it doubles winnings when you get it. The scatter symbol is a lion, which can reward wins even when it isn’t in the payline. If you get 5, it will pay up to 500x the bet value. When three or more appear, you can earn free spins!

Bonus Rounds & Free Spins

The free spins round is triggered through the scatter symbol, where you can win up to 15 free spins per round with a 3x multiplier. After each winning spin, there’s the option to “take a risk”. This is a gamble function to bump up your winnings instantly. 

The King Hits & Misses

No slot game is for absolutely everyone, so here are some pros and cons in The King:

  • Advantages

  • Decent return to player of 96%
  • Great medieval theme by Endorphina Software
  • Ten pay lines with loads of options
  • The Scatter function works across pay lines
  • Bet from a single credit all the way to 100
  • Limitations

  • Getting the free spins bonus is a little difficult


This slot is another winner for Endorphina Software, especially for those who enjoy the theme. It also features a lot of ways to win and boasts a solid RTP as well. It’s the kind of game players will go back to, time after time.
