Fire Portals Slot Review
Fire Portals is Pragmatic Play’s latest venture into cosmic gaming, combining a mystical theme with one of the industry’s most popular mechanics. Released in March 2024, this 7×7 grid slot delivers an immersive experience with celestial visuals and magical portal aesthetics that immediately capture attention. The game strikes a compelling balance between innovative wild mechanics and high volatility gameplay, making it ideal for experienced players seeking substantial win potential. With its impressive **96.06% RTP** and **10,000x maximum win**, Fire Portals has quickly become a standout title among cluster pays enthusiasts.
Base Game & Features
Fire Portals operates on a **7×7 grid layout**, moving away from traditional paylines in favour of **cluster pays mechanics**. To form a winning combination, you’ll need **5 or more adjacent symbols** positioned vertically or horizontally on the grid. This structure creates multiple win possibilities per spin, significantly increasing the frequency of winning opportunities compared to fixed payline slots.
Fire Portal Wilds Mechanic
The standout feature of Fire Portals is undoubtedly the Fire Portal Wilds system. These special symbols arrive randomly on the reels and begin with a **x1 multiplier**. Each time a Fire Portal Wild participates in a winning cluster, its multiplier increases by **+1**, creating escalating win potential across consecutive spins. What truly sets this mechanic apart is the merging behaviour—when two or more Fire Portal Wilds form part of the same winning combination, they merge together and their multipliers **multiply each other**, rather than simply adding up. This exponential growth can generate extraordinary payouts, with the maximum wild multiplier reaching an impressive **x2500**. This innovative feature is genuinely exciting and stands out among cluster pays titles for its fresh approach to multiplier systems.
Tumble Feature
After each winning cluster, the **tumble feature** activates automatically. Winning symbols disappear from the grid, allowing new symbols to cascade down and fill the vacant spaces. This cascading action can create consecutive wins in a single spin sequence, amplifying your potential returns significantly. The tumble mechanic pairs exceptionally well with the Fire Portal Wilds, as each tumble win increases the wild multipliers further, building momentum towards larger payouts.
Fire Portals Free Spins & Bonus Features
The bonus round stands as the pinnacle of Fire Portals’ gameplay experience. Landing between **3 and 7 Book Scatter symbols** anywhere on the grid triggers the free spins feature, awarding between **10 and 18 free spins** depending on the scatter count. The more scatters you land, the more spins you receive: 3 scatters grant 10 spins, 4 scatters award 12 spins, continuing up to 7 scatters for a generous 18 spins.
What makes the free spins round genuinely compelling is the **sticky wild behaviour**. Fire Portal Wilds that land during the bonus round remain **locked in place for the entire duration** of your free spins, continuously building their multipliers with each subsequent win. This creates sustained win potential throughout the round, allowing multipliers to accumulate substantially before the feature concludes. The combination of sticky wilds and cascading wins transforms the free spins round into a high-octane bonus experience where Fire Portal Wilds can achieve exceptional multiplier values.
Bonus Purchase Options
For players who prefer direct entry into the bonus round, Fire Portals offers two purchase features. The **Bonus Buy option** costs **100x your current bet** and instantly triggers the free spins with randomly generated scatter counts. Alternatively, the **Ante Bet feature** increases your stake by **25% per spin**, which enhances both the scatter symbol presence on the grid and the probability of triggering the free spins naturally. Both options cater to different player preferences and bankroll strategies.

Our Honest Verdict
Fire Portals earns a solid **7.5/10 rating**, representing a genuinely entertaining and innovative cluster pays slot that delivers on both visual appeal and mechanical depth. The Fire Portal Wilds mechanic is exceptional—the merging multiplier system feels fresh and genuinely exciting, setting this game apart from the crowded cluster pays category. The 96.06% RTP sits slightly above industry average, and the potential for 10,000x maximum wins creates compelling incentive for extended play sessions.
However, Fire Portals isn’t without drawbacks. This is a **high volatility slot**, meaning wins occur less frequently but potentially at larger magnitudes. Extended periods of dead spins can occur even when multiplying wilds have built momentum, which can frustrate players seeking consistent returns. The bonus round, whilst visually spectacular with sticky wilds, sometimes underperforms relative to player expectations—free spins rounds can shut down in dead spin sequences rather than escalating wild multipliers as anticipated.
The game is best suited for **experienced players and thrill-seekers** who appreciate high-volatility gameplay and can tolerate variance in exchange for the excitement of potential substantial wins. If you’re a fan of cluster pays mechanics with innovative twists—similar to titles like Jammin’ Jars—Fire Portals deserves serious consideration. The mechanical innovation and visual presentation are standout features. Conversely, if you prefer consistent smaller wins or lower volatility gameplay, you might find the swings of Fire Portals too unpredictable. Overall, Fire Portals is destined to remain popular due to the immense appeal of its cluster pays foundation and genuinely innovative multiplier mechanics, making it a worthwhile addition to any experienced player’s rotation.
