Fisher King online slot review
In Evan Carrington’s Casino Ideal review, the Fisher King online slot features a free spins bonus where the Holy Grail can award up to 2,000x a spin bet. During the free spins, healing broken hearts can raise the spin-bet multiplier from 3x to 2,000x. To reach the Holy Grail, scatter symbols must land to open the doors to the ancient relic.
Theme and story line
The Fisher King is confined to his castle after an injury that may prove fatal. His only remaining choice is to fish from a small boat circling the castle and leave the outcome to fate. The story takes a turn when a noble slot enthusiast arrives at the palace and helps uncover the healing power in the Holy Grail’s lifeblood.
Graphics, sounds and animations
A glittering scene features the Fisher King’s golden treasure chests and crowns. The reels give their symbols Endorphina’s familiar, clear treatment Endorphina. A winning combination brings an animation of gold coins pouring from a fountain, while the free spins bonus adds effects when the Holy Grail symbol appears. The sound design is restrained rather than overpowering.

Top Casinos to Play Fisher King:
Gameplay
Across the 5x3 reels, the game has 8 regular symbols, a scatter and a wild, with 20 paylines available. You can adjust the number of active lines from 1 to 20. ‘Fisher King’ pays the most, followed by the knightly warrior and then the princess; playing-card icons occupy the lower-paying positions. The ‘Wild Gold Crown’ substitutes for any of the 8 regular symbols, but not the scatter. Landing that scatter is important on each spin because it leads to ‘Free Games with the Holy Grail Feature’.
Payouts for 5 matching symbols are listed below:
- Fisher King: 50x
- Knight: 30x
- Princess: 20x
- Ace: 17.50x
- King ‘or’ Queen: 6.25x
- Jack ‘or’ 10: 5x
Bonuses and free spins
Free Spins: Landing 3, 4, or 5 ‘Heart’ scatter symbols awards 10, 15 or 20 free spins respectively. Since scatters can appear during free spins, the same number of spins may be triggered again.
Holy Grail Feature: In the free spins round, the ‘Holy Grail’ can reveal multipliers applied to the spin bet. Each appearance fills the divided hearts below the reels. Filling 1, 2, 3, 4, or 5 hearts with the Holy Grail gives 3x, 10x, 50x, 500x, or 2,000x the bet.
Gamble Feature: After a reel win, you can choose the gamble option. 4 cards are shown, and your choice must beat the dealer’s card to double the winnings. You can gamble again or leave the feature with the winnings already displayed.

Bet sizes, RTP and variance
In Evan Carrington’s Casino Ideal review, Fisher King offers two ways to set your stake. Choose ‘Coin Value’, where the value is multiplied by 20 paylines, or enter the full spin amount using ‘BET’. The stated minimum-to-maximum range is 0.01-200.00, while theoretical RTP remains 96.02%. The reels have medium-to-high variance.
Conclusion
The review suggests that larger Fisher King wins may be more closely linked to triggering the free spins bonus, though it also describes the base game as generating a notable number of combinations. With just 8 regular symbols across 20 pay lines, fewer symbols may be competing for the same positions. The wild can help complete winning combinations as players pursue the Holy Grail free spins feature, which is said to award up to 2,000x a spin bet. These are game features and reported observations, not promises of wins or bankroll growth.
