This distinctive blend of elements propels "Hellcatraz" to the forefront of online slots, showcasing Relax Gaming's commitment to innovation. Dive into the world of "Hellcatraz," where every spin is an opportunity for excitement and discovery in the evolving landscape of virtual slot entertainment.

Hellcatraz Features

Hellcatraz stands out with a myriad of cool features, including the Buy Feature, FreeSpins, Mystery Symbol, RTP Range, Symbols Collection (Energy), and Wilds, providing players with a multifaceted and thrilling gaming experience. The abundance of features ensures there's never a dull moment, making it a standout choice for those seeking excitement and variety in their slot gameplay.

Buy Feature

In the Hellcatraz slot, the Buy Feature is an option that allows players to directly purchase access to the Free Spins feature instead of waiting for it to be triggered organically during gameplay. This feature provides a shortcut for players who are eager to experience the excitement of the Free Spins round without relying on the typical conditions for activation. Typically, the Buy Feature comes at a cost, and the price may vary depending on the specific game and the current bet level. By choosing to activate the Buy Feature, players essentially pay a premium to initiate the Free Spins feature instantly, providing immediate access to the heightened thrills and increased winning potential associated with Free Spins.


In the Hellcatraz slot, the Free Spins feature is a bonus round that can significantly enhance the player's gaming experience. To trigger the Free Spins, players typically need to land a specific combination of symbols or fulfill certain in-game conditions. Once the Free Spins feature is activated, players are awarded a predetermined number of free spins, during which they can enjoy the game without using their own funds. The number of free spins granted often depends on the specific circumstances triggering the feature. What makes the Free Spins feature particularly exciting in Hellcatraz is its potential for increased winning opportunities. During the Free Spins round, special enhancements or modifiers may come into play. These could include additional wild symbols, higher multipliers, or other bonus features that can amplify the rewards for each spin.

Mystery symbol

In the Hellcatraz slot, the Mystery Symbol is a game element that adds an element of surprise and excitement to the gameplay. When Mystery Symbols appear on the reels, they transform into a random, predefined symbol after the spin concludes. This transformation occurs simultaneously for all Mystery Symbols present on the reels. The Mystery Symbol's ability to morph into any other symbol, except for special symbols like Wilds or Scatters, can lead to unexpected winning combinations. This adds a dynamic and unpredictable dimension to the game, enhancing the overall entertainment value for players.

Symbols collection (Energy)

In the Hellcatraz slot, the "Symbols Collection (Key)" feature adds an engaging layer to the gameplay. When playing, you have the opportunity to land small golden keys on top of regular symbols. These keys are collected in a meter located on the left-hand side of the reels. Each golden key collected contributes to filling the meter. Notably, each key can provide a variable contribution, ranging between 1 and 10 keys added to the meter. The randomness in the number of keys obtained adds an element of unpredictability and excitement to the collection process. To trigger the Super Free Spins bonus round in Hellcatraz, players need to accumulate a substantial number of keys. Specifically, the meter must be filled with 2,000 keys. While you can land keys frequently during gameplay, the task of collecting 2,000 keys indicates that triggering the Super Free Spins bonus round is a more extended and strategic process.


In most slot games, including Hellcatraz, the Wild symbol is a special symbol with versatile functions that can significantly enhance gameplay. The Wild symbol acts as a substitute for other regular symbols on the reels, helping players complete winning combinations. For instance, if you have two matching symbols on a payline along with a Wild symbol, the Wild will function as the missing third symbol, resulting in a winning combination.

Hellcatraz Unique Features

Hellcatraz, a creation by Relax Gaming, stands out in the world of online slots with its diverse and unique features. The "Buy Feature" is a standout option, providing players with the opportunity to instantly delve into the exhilarating Free Spins round. This feature not only adds convenience but also intensifies the overall thrill of the game.

The Free Spins feature, a beloved classic, takes players on a complimentary spin journey, often accompanied by special enhancements that elevate the potential for significant wins. It's a player-favorite element that encapsulates the essence of excitement and anticipation.

The "Mystery Symbol" in Hellcatraz adds an intriguing twist to the gameplay. With each spin, these symbols unfold into random symbols, injecting an element of surprise and creating dynamic opportunities for rewarding combinations.

Hellcatraz also introduces a unique "Symbols Collection (Energy)" mechanic. Here, players collect energy symbols, unlocking special bonuses and adding a layer of strategy to the gaming experience. This feature encourages engagement and a sense of progression as players work towards unlocking additional in-game rewards.

The inclusion of a dynamic RTP range further enhances the game's unpredictability, ensuring that every spin brings with it an element of uncertainty and excitement. Lastly, the classic "Wild" symbol takes its place, serving as a versatile substitute and significantly increasing the chances of completing winning combinations.

The Correction Officer symbol takes the lead, offering a substantial 2x payout for landing 6 on a payline. 

Following closely, the Prisoner symbol brings a respectable 1.2x payout for achieving a line of 6 on the reels. 

Hellcatraz Winning symbols

The Shark symbol holds its own, providing a 1x payout for a combination of 6 on a payline. 

The Guard's Badge and Handcuffs symbols offer additional winning opportunities, with payouts of 0.8x and 0.6x, respectively, for a line of 6 on a payline.

The Wild symbol in Hellcatraz is represented by a simple orange W. This versatile symbol steps in for all regular symbols, acting as a helpful substitute to form winning combinations and enhance the overall winning potential. Adding to the dynamic gameplay is the cascading wins feature. When winning combinations occur, the corresponding symbols are removed from the reels, making way for new symbols to fall from above. This innovative mechanic allows for multiple wins on a single spin, creating a cascading effect that continues as long as new winning combinations are landed. The combination of distinctive winning symbols and the cascading wins feature makes Hellcatraz an engaging and rewarding slot experience for players seeking both variety and potential payouts.
