The Incredible Hulk 50 Lines Slot Review
The Incredible Hulk 50 Lines is a 5-reel, 50-payline video slot from Playtech, released as an expanded version of their earlier 25-line Hulk game. It carries a 94.82% RTP and bets range from £0.01 to £500 per spin. The game was discontinued in April 2017 when Playtech's licensing deal with Marvel - and by extension Disney - came to an end. You won't find it in active casino lobbies today, but it remains one of the more feature-packed Marvel slots Playtech produced.
The theme is built around the classic comic book Hulk, not a specific film adaptation. That means deep greens, smashed police cars, radioactive symbols, and Bruce Banner's scientific paraphernalia all feature heavily across the reels. The soundtrack is functional rather than exciting - a minor fault in an otherwise well-constructed game.
Symbols and Paytable
The reels carry a mix of thematic and standard symbols. At the top end you have the Hulk himself, then helicopters, police cars, radioactive hazard signs, beakers of green liquid, and the Hulk logo. Standard playing card values from 9 through Ace fill the lower-pay positions. The Hulk symbol doubles as the wild, and the game logo acts as the scatter.
The Smash Bonus symbol is the key to the second-screen bonus round - it needs to land on both reel 1 and reel 5 simultaneously to trigger. That dual-reel requirement makes it relatively rare, but the payoff when it fires is worth the wait.
Wild and Expanding Wild Mechanics
The Hulk wild only appears on reels 2, 3 and 4. It substitutes for all symbols except the scatter and Smash Bonus. Two specific conditions trigger expanded behaviour:
- If the Hulk lands in the centre position of reel 3, he expands to fill the reel and you receive 2 free spins with the expanded wild held in place.
- If the Hulk lands simultaneously on all three of reels 2, 3 and 4, the remaining two reels (1 and 5) spin backwards - a mechanic that regularly produces strong winning combinations.
The reverse-reel mechanic in particular makes this slot feel distinct from Playtech's other Marvel titles. It's not just cosmetic - the backwards spin changes outcome frequency on those reels in a way that registers during play.
Free Spins Feature
Three or more scatter symbols (the game logo) anywhere on the reels triggers the Scatter Pay Zone. You receive 10 free spins with a 3x multiplier applied to all wins. During this feature the Hulk logo can also triple wins independently, giving a potential stacking effect with the base multiplier. The feature can be retriggered if you land three more scatters during the bonus round.
Landing five radioactive hazard symbols pays 12,000x your stake - the top fixed symbol win in the base game.
Smash Bonus Round
When the Smash Bonus symbol appears on both reel 1 and reel 5 at the same time, you enter the Smash Bonus game. The setup is straightforward: seven police cars and three helicopters are lined up, and you pick three cars to smash for cash prizes. Selecting a helicopter reveals a win multiplier instead. The Random Rage feature can trigger spontaneously during this round, causing the Hulk to destroy all seven cars at once - the maximum outcome for this bonus.
Marvel Mystery Progressive Jackpot
The Incredible Hulk 50 Lines was part of Playtech's linked Marvel Mystery Jackpot network, which connected multiple Marvel-licensed slots. The four jackpot tiers were Power, Extra Power, Super Power and Ultimate Power. The jackpot triggered randomly - no specific symbol combination required. Higher bets increased the probability of the jackpot game appearing. Once triggered, a grid of 20 squares was revealed; match three identical symbols to win that jackpot tier. Every bet placed contributed to the jackpot pool.
This progressive network no longer operates. With the Marvel licence gone and the games removed, the jackpot system was retired alongside them.
How It Compares to Other Superhero Slots
Playtech built several superhero-licensed slots before the Marvel deal ended. Iron Man 2 and X-Men used similar bonus frameworks with the same four-tier progressive jackpot. Fantastic Four ran on an identical structure. DC-branded titles on other platforms followed comparable paths - Superman and The Flash both offered branded progressive jackpots before their respective licences lapsed. The 50-line Hulk game expanded on the original 25-line version by doubling the paylines, which increases hit frequency and makes the base game feel more active. The reverse-reel mechanic sets it apart from most contemporaries in the genre.
For current Playtech slots in a similar style, their Age of the Gods series replaced the Marvel range and uses a comparable progressive jackpot structure. You can browse available titles on our casino listings page.
Verdict
The Incredible Hulk 50 Lines delivered a well-structured slot for its era. The expanding wild with 2 free spins, reverse-reel mechanic, 10 free spins at 3x, and the Smash Bonus round gave players multiple distinct ways to win beyond the base game. At 94.82% RTP it sat in a reasonable range for its time, and the £0.01 minimum made it accessible at all stake levels.
The game is discontinued and unavailable at regulated UK casinos. It stands as a solid example of what Playtech produced during their Marvel licensing period - feature-rich, thematically coherent, and more mechanically interesting than many contemporaries. The loss of the Marvel licence in 2017 ended what had been one of the more popular progressive slot series in online gaming.
