Champions of Mithrune is an epic online slot from the fantasy masters at Play'n GO Games, transporting players to a high fantasy realm where a fellowship of heroes battles the encroaching darkness of the Dark Lord Duran. This game stands out for its deep, narrative-driven mechanics, featuring five unique, randomly triggered Champion modifiers in the base game and a multi-stage Free Spins bonus that builds tension and increases win potential exponentially. Launched in 2022, the slot combines stunning visuals and an epic soundtrack with high volatility and a maximum payout of 7,500x the bet, cementing its status as a must-play title in the Play'n GO portfolio for enthusiasts of feature-rich video slots.
The Champions of Mithrune slot is set on a classic yet expansive 5x5 reel layout with 20 fixed paylines, offering plenty of opportunities for winning combinations. The symbols are richly designed, featuring the five powerful Champions as the high-paying premium symbols: Syn the Shapeshifter, Gorm the Barbarian, Silvana the Ranger, Olc the Goblin, and Anastina the Sorcerer. Low-value symbols are represented by card suits (A, K, Q, J, 10) rendered as metallic emblems. The game’s Wild symbol, often depicted as a golden rune, substitutes for all regular paying symbols. The visual aesthetic is immediately immersive, placing the player right into the heart of a war-torn but magical kingdom, perfectly setting the stage for the high variance action that follows.
The core of the base game's excitement lies in the five distinct Champion features, which can be randomly triggered on any spin. These modifiers are the player's greatest tool for achieving unexpected wins and maintaining engagement while hunting for the main bonus. Each Champion's power directly relates to their character and provides a different type of reel enhancement:
Syn the Shapeshifter: The most potent Champion. Syn will randomly transform one type of Champion symbol on the reels (Gorm, Silvana, Olc, or Anastina) into the highest-paying Syn symbol, and all other visible instances of that same Champion symbol will also transform to match, creating higher-value five-of-a-kind combinations.
Gorm the Barbarian: The clear-out specialist. Gorm smashes the reels, upgrading all instances of one low-value card suit symbol (10, J, Q, K, or A) into the powerful Wild symbol, dramatically increasing the number of active Wilds on the screen.
Silvana the Ranger: The sharpshooter. Silvana fires her arrows with precision, scattering 4 to 7 extra Wild symbols randomly across the 5x5 grid, offering immediate boosts to payline potential.
Olc the Goblin: The reckless rogue. Olc unleashes his magic, turning between one and three entire reels into Stacked Wilds, covering all positions on those reels and guaranteeing wild lines for huge payouts.
Anastina the Sorcerer: The elemental force. Anastina summons a colossal Mega Symbol cluster, placing a large block of matching symbols (ranging from 2x2 to a full 5x5) onto the reels, guaranteeing a cluster win.
These random features ensure that no two spins are the same, providing continuous action and making the base game far more dynamic than typical slots.
The main bonus round, where the largest slot payouts can be achieved, is triggered by landing three Scatter symbols—represented by the menacing face of the Dark Lord Duran—on reels 1, 3, and 5. This combination does not immediately launch the Free Spins; instead, it initiates an exciting, multi-stage Power Up feature mini-game, a unique addition that allows the player to enhance the Free Spins round before it even begins. This pre-feature game adds an extra layer of strategy and anticipation to the overall bonus structure.
The Power Up feature takes place on an empty 5x5 grid and utilizes a Hold and Win or streak-respin style mechanic. The player is given three "lives" (respins). The reels only contain special symbols: Champion Tokens, Multiplier Potions, and additional Scatters. The goal is to collect these symbols to power up the upcoming Free Spins.
Champion Tokens: Collecting three of a single Champion's token will unlock that Champion's modifier for the entire duration of the subsequent Free Spins round, guaranteeing that their power activates on every spin.
Multiplier Potions: Collecting three Multiplier Potions increases the win multiplier by x1, up to a maximum of x10. This multiplier applies to all wins during the Free Spins.
Scatters: Collecting three additional Scatters adds 1 to the starting count of Free Spins, up to a maximum of 10 initial spins.
Landing any of these symbols resets the lives counter back to three. The mini-game ends only when the player runs out of lives, after three consecutive spins without a special symbol landing. This crucial setup determines the volatility and potential size of the main bonus.
Once the Power Up mini-game concludes, the player enters the Champions Free Spins round with their collected enhancements activated. The number of spins is determined by the initial trigger plus any collected Scatters from the Power Up feature. During the Free Spins, any Champion whose token was successfully collected will have their feature activate on every single spin. For instance, if the player collected Gorm and Olc tokens, then every free spin will feature Gorm's Wild upgrade and Olc's Stacked Wilds. Any collected Win Multiplier (up to 10x) is applied to all line wins throughout the entire bonus round. This combination of guaranteed, stacked modifiers and a potential multiplier is the engine for the slot's massive 7,500x max win potential, making the Free Spins the most important part of the online gambling experience.
The Champions of Mithrune slot is a prime example of Play'n GO's typical game design, offering an RTP (Return to Player) that often defaults around 96.25%, although it should be noted that Play'n GO offers multiple RTP settings, and players should verify the rate at their chosen online casino. The game is characterized by High Volatility, meaning that while smaller wins may be frequent due to the base game modifiers, the truly massive payouts are highly concentrated within the Free Spins bonus round. This high-risk, high-reward model is perfectly suited for the game's epic fantasy theme and appeals to players seeking monumental single-session returns. The high variance requires prudent bankroll management to sustain play until the highly lucrative bonus is triggered.

As a modern Play'n GO Games release, Champions of Mithrune is fully optimized for mobile slots play via HTML5. The detailed graphics, smooth animations, and complex bonus features translate flawlessly to both Android and iOS devices, ensuring a premium gaming experience on the go. The slot is also significant as the progenitor of the Mithrune series, followed by a sequel (Tales of Mithrune Syn's Fortune), demonstrating Play'n GO's commitment to building rich, interconnected fantasy universes within their slots series—a strategy that appeals to players who enjoy deep lore and recurring characters. The game's success lies in its ability to deliver both strong aesthetics and innovative, layered feature mechanics.
Given the high volatility and the multi-stage nature of the bonus round, a strategic approach to Champions of Mithrune should focus on longevity and maximizing the Power Up feature. Players should aim for the European RTP rate (96.25%) if available. Since the major rewards are gated behind the Free Spins and the subsequent Power Up mini-game, betting levels should be chosen carefully to allow for a significant number of spins to weather the base game variance. When the Power Up feature is triggered, the priority should be collecting the Champion Tokens, as the guaranteed modifiers on every spin provide the most consistent route to large slot payouts, especially when combined with a collected Multiplier. The game rewards patience and discipline in the pursuit of the combined Champion and Multiplier bonus effect.
The Champions of Mithrune slot offers a maximum win potential of 7,500x the player's total bet. This significant payout is primarily achievable through a successful Free Spins round where multiple Champion modifiers and a high win multiplier have been collected during the preceding Power Up feature.
The five Champion Modifiers (Syn, Gorm, Silvana, Olc, and Anastina) are triggered randomly on any base game spin. Each Champion provides a unique reel enhancement, such as adding extra Wilds (Silvana), upgrading symbols to Wilds (Gorm), or transforming entire reels into Stacked Wilds (Olc), significantly boosting the spin's win potential.
The Free Spins feature is initiated by landing three Scatter symbols (the Dark Lord Duran) on reels 1, 3, and 5. This trigger leads not directly to the spins, but to the Power Up feature mini-game, where players can collect bonuses to enhance the subsequent Free Spins round.
The Power Up feature mini-game is a streak-respin round designed to enhance the upcoming Free Spins. Players collect Champion Tokens (to guarantee their modifier on every spin), Multiplier Potions (to increase the overall win multiplier up to 10x), and extra Scatters (to earn additional free spins).
The Champions of Mithrune slot is a High Volatility game. The default RTP (Return to Player) is typically 96.25%, though it is important for players to check the specific RTP setting offered by their online casino, as Play'n GO games can feature multiple return-to-player configurations.
Syn the Shapeshifter offers the highest potential symbol upgrade. When Syn's modifier is triggered, it targets one of the other four Champion symbols currently on the reels and transforms that Champion symbol, and all other visible instances of it, into the highest-paying Syn symbol, maximizing line win values.
Collecting three matching Champion Tokens during the initial Power Up mini-game guarantees that the corresponding Champion's special modifier will be active and will be triggered on every single spin for the entire duration of the Free Spins round.
The maximum win multiplier available in the Champions of Mithrune Free Spins is 10x. This is achieved by successfully collecting all required Multiplier Potions during the pre-feature Power Up mini-game, with each successful collection increasing the multiplier by x1.
Olc the Goblin is responsible for placing Stacked Wilds on the reels. When his modifier is triggered, Olc randomly turns one, two, or three entire reels into full Wild reels, significantly increasing the chance of five-of-a-kind wins across multiple 20 paylines.
Gorm the Barbarian's modifier increases the number of Wilds by upgrading low-paying symbols. Gorm smashes the reels and transforms all instances of a randomly chosen low-value card suit symbol (10, J, Q, K, or A) into the highly valuable Wild symbol for that spin.
