Introduction
Endorphina clearly knows that the mythology of King Arthur has an enduring appeal; why else would they name a slot Fisher King? At first glance, the 5-reels could be in any Medieval castle and the 20 paylines seem fairly standard, but if you’re lucky enough to trigger free spins, you also have the chance to find the Holy Grail and win some massive prizes.
Theme, Graphics & Soundtrack
The Fisher King isn’t quite as famous as Guinevere or Sir Lancelot, but he’s pretty important to Arthurian mythology. Journey back to Ancient Britain when King Arthur and his knights searched for the Holy Grail, the cup Jesus drank from at the Last Supper. It is Sir Percival, sometimes with the help of Sir Galahad and Sir Bors, who eventually finds it in the castle of the Fisher King.
The Fisher King has an old injury that leaves him unable to stand. He spends his days in a small boat, fishing as he waits to be healed. This injury isn’t on display in the Fisher King slot, where king, hero and lady are big, bold symbols surrounded by traditional card icons. They’re in what appears to be the royal treasure chamber, surrounded by enticing piles of gold and an ominous-looking skull.
It has to be said that the Arthurian part of this game isn’t particularly prominent outside of the Holy Grail bonus feature. It could, like many online slots, be generically Medieval. It does look good, though, and there are interesting sound effects.

Fisher King RTP and Variance
For any slot machine, an RTP of 96.02% is solid. It’s the sort of level we expect, even allowing for natural statistical deviation.
When you play a no deposit slot for free, it means less risk. The variance of Fisher King is medium to high, which means that it should be mostly balanced but leans towards the higher risk of a high-variance game.
How to Play Fisher King
This is a real slot machine quest!
- If you’ve played any online slots from Endorphina before, this layout will look familiar. Up in the top corner are mute and full screen buttons as well as a link to the paytable.
- The menu opens a statistics page with useful information such as how long you’ve been playing (if it’s longer than you thought, please take a break) and how much you’ve both staked and won (are you sticking to your limits?).
- Other menu pages include autoplay, language, sound (with separate sliders for master sound, effects and background sound) and a miscellaneous page to change from money to credit display, to set a reality check to stop you playing too long, and to choose low, medium or high-quality graphics.
- Change the number of paylines, coin value and bet by clicking those specific displays. Activate turbo or autoplay as well by clicking.
- Go back to autoplay in the menu if you want to include your limits, or hit the regular spin button to play and have fun.
Always play responsibly.
Bet & Win Sizes
Every slot machine, even if it’s a no deposit slot that you’re playing for free, starts by making a bet. The coin value in the Fisher King online slot goes from 0.01 to 1, while the bet is between 0.01 and 0.10.
What could that win? Here are the values for matching 5 symbols with a minimum bet:
10, J - 1.00
Q, K - 1.25
A - 3.50
Lady - 4.00
Hero - 6.00
Fisher King - 10.00
Fisher King Bonus Features
A lot of online slots have free games, but they’re not all this creative at incorporating their theme:
Free Games
3 scatters = 10 free games.
4 scatters = 15 free games.
5 scatters = 20 free games.
It’s not as simple as free games, however, and this is when the Holy Grail arrives.
Holy Grail Feature
The Fisher King was injured, and the grail helped him heal. When the grail lands in this slot, it pours its lifeblood into the broken hearts beneath. Two drops of blood will replenish the heart, and this means you receive a reward.
1 heart = 3x total bet.
2 hearts = 10x total bet.
3 hearts = 50x total bet.
4 hearts = 500x total bet.
5 hearts = 2000x total bet.
Fisher King Review
Our Fisher King slot review has covered Fisher King from top to bottom. The base game is kind of generic, but the addition of the Holy Grail in the free spins round dramatically increases the possible total prizes. We’re also very happy about the reality check and limits in autoplay that can keep your gaming responsible.
If you want to look elsewhere, consider visiting Ancient Egypt with the 4 Secret Pyramids slot, or try out our diverse range of Kalamba Games slots on offer.

FAQs
What is the RTP of Fisher King?
We call RTP an average, and Fisher King’s RTP is as average as can be. The 96.02% is almost precisely on the 96% mark that characterises modern slots. What you have to remember is that most individual slot games won’t be average. They go higher or lower before (possibly) evening out.
What is the variance of Fisher King?
This slot has a variance somewhere between medium and high. In medium-variance slots, there’s a balance between size and frequency of wins. High variance means the risk increases because wins will be rarer, but when they do hit, they could be very large. Play as a free, no deposit slot to reduce the risk.
How does Fisher King’s Holy Grail feature work?
It starts with a free spins round, which is exciting but still pretty standard. You can win up to 20 free spins by finding scatters, but it’s during the round that Holy Grail symbols come into play. They drip lifeblood into broken hearts to heal them, and the more hearts you replenish, the bigger your reward. It goes up to a massive 2000x your bet.
