ThunderCats Reels of Thundera

ThunderCats Reels of Thundera: Slot Overview 

Released on June 4, 2019, ThunderCats Reels of Thundera by Blueprint Gaming brings the legendary 1980s animated series ThunderCats to the reels, combining nostalgic cartoon energy with Blueprint’s signature feature-heavy gameplay. This 5-reel, 3-row online slot offers 20 fixed paylines, a 95.73% RTP, and medium-to-high volatility, with the potential to win up to 10,000x your stake. 

The slot celebrates the iconic Warner Bros. franchise, originally produced in Japan and later adapted for Western audiences, following the adventures of Lion-O, Panthro, Cheetara, Tygra, WilyKit, and Snarf. True to the show, the slot immerses players in the world of Thundera — a volcanic landscape filled with molten lava, swords, and ThunderTanks. 

ThunderCats Reels of Thundera forms part of Blueprint’s growing library of branded titles, alongside hits like The Goonies, Mars Attacks!, and Beavis and Butt-Head. Fans of those releases will find this one familiar: packed with random reel modifiers, multiple free spin features, and bonus rounds tied to the characters. The result is a vibrant, action-filled slot that captures the essence of the show while offering plenty of ways to win. 

Playable from €0.10 to €200 per spin, it caters to all player types — from cautious spinners to high-stakes fans — and boasts high entertainment value even outside of the bonus rounds.

Design and Graphics 

Blueprint has done an excellent job translating the retro cartoon aesthetic of ThunderCats into a modern slot experience. The design is brimming with 1980s nostalgia — bold, saturated colors, dynamic animations, and faithful recreations of the show’s characters and symbols.

The reels are set against a dramatic backdrop of molten lava flowing through rocky terrain, with the Eye of Thundera glowing ominously above. The artwork combines classic 2D cartoon imagery with polished digital shading, giving the game a stylized comic-book look. 

On the reels, you’ll find low-value symbols represented by the classic royals (J, Q, K, A) and high-value symbols including nunchakus, swords, surfboards, ThunderTanks, and of course, the ThunderCats logo, which is the most lucrative — awarding 50x your stake for five of a kind. 

The wild symbol substitutes for all regular icons except scatters and plays a crucial role in many modifiers. Meanwhile, the ThunderCats scatter logo is your ticket to the game’s numerous bonus rounds. 

Blueprint has clearly put effort into aligning every visual detail with the franchise’s tone. The result is a slot that feels like a playable tribute to the series rather than a lazy rebrand.

Gameplay Mechanics 

The base game operates on a 5×3 grid with 20 paylines, and winning combinations are formed by landing matching symbols from left to right starting on the first reel. The volatility sits in the medium-to-high range, offering a balance between frequent small wins and the potential for substantial rewards during feature rounds. 

While the structure is straightforward, ThunderCats Reels of Thundera keeps gameplay exciting through frequent random modifiers and bonus triggers. The “Awaken the Eye of Thundera” feature can activate at any time, granting one of six reel enhancements based on the main characters: 

Lion-O – Adds wilds to the reels, boosting the chance of big wins. 

Tygra – Swipes the reels, turning them wild; retriggers possible. 

Panthro – Links between 2 and 5 reels together with identical symbols. 

Cheetara – Dashes across the reels, reshuffling all symbols up to 5 times for new combinations. 

WilyKit & WilyKat – Add Mystery Symbols that transform into a matching icon. 

Snarf – Adds scatter symbols, increasing the likelihood of triggering the bonus. 

These modifiers ensure that even the base game remains highly interactive. Combined with strong payout potential and satisfying animations, it creates a gameplay loop that feels dynamic and true to Blueprint’s style.

Sound and Music 

One of ThunderCats Reels of Thundera’s standout features is its sound design. From the instant the reels spin, players are treated to a high-energy soundtrack reminiscent of the original TV series. The background music blends electric guitar riffs and heroic synth beats, evoking the intensity of 1980s action cartoons. 

During special features and modifiers, the soundtrack shifts dynamically — drums pick up, guitars intensify, and fan-favorite voice clips from the show make appearances. The authentic sound bites for Lion-O and the Eye of Thundera give the slot a distinct personality that long-time fans will appreciate. 

Blueprint also nails the smaller details: cascading metal clinks during reel spins, fiery whooshes for symbol reveals, and satisfying celebratory jingles after wins. The overall audio mix perfectly complements the visual spectacle, capturing the excitement and adventurous spirit of the series.

Bonus Features 

The bonus round variety in ThunderCats Reels of Thundera is remarkable, offering several free spin modes and reel modifiers tied to different characters. Triggered by landing three or more ThunderCats scatter symbols, the Bonus Wheel spins to determine which feature you’ll play. Although the wheel tends to favor the lower-value bonuses, players can gamble their reward for a higher-tier feature — at the risk of losing it entirely. 

Here’s a breakdown of each main feature: 

Sight Beyond Sight 

Pick an Eye of Thundera to reveal one of four outcomes: 

Lion-O – Increases the cash multiplier. 

ThunderCats Logo – Upgrades existing cash multipliers. 

Mumm-Ra – Ends the feature. 

ThunderTank – Triggers another random bonus. 

The Black Pyramid 

Select from emblems to reveal three possible results: 

Lion-O – Moves your marker upward, advancing toward higher rewards. 

ThunderCats Logo – Boosts your cash multipliers. 

Mumm-Ra – Ends the round. 

Landing on an arrow moves you further up the pyramid, unlocking more lucrative prizes or triggering a follow-up feature. 

The Ever-Living Free Spins 

Applies a random multiplier (x2–x5) to wins on each spin. Landing 2+ Mumm-Ra symbols retriggers the feature with a higher multiplier (x6–x10). It’s volatile and packed with potential. 

Hear the Roar Free Spins 

If a Lion-O symbol lands, it upgrades adjacent symbols to higher-value icons. This can happen up to four times per spin, leading to rewarding chain reactions. 

ThunderCats Hooo! Free Spins 

Any wilds that land remain locked for the duration of the feature. Fill a full reel with wilds to earn five additional spins. 

Ancient Spirits of Evil 

Triggered by 5 scatters or through the bonus wheel landing on this mode. Players spin for cash prizes and potential upgrades: 

Lion-O spins the wheel. 

Mumm-Ra ends the feature. 

ThunderCats Logo upgrades multipliers.
Landing on the red arrow moves you to the next ring, with the center awarding the Ultimate Thunder Bonus.
