Hellcatraz Online

The Hellcatraz game was launched in 2020 and managed to offer players something truly new. It’s not just another slot machine with a unique design; it’s a slot with unique mechanics and features. Relax Gaming has since released similar games, but this slot remains one of the most interesting in the developer’s catalog.

The Hellcatraz game board consists of 6 reels and 6 rows, with winnings available on 46,656 paylines. Before playing, you can choose the volatility level, but it will always be high. The RTP is 96.46%, suggesting that the slot machine can be profitable. I’ll tell you all the details in this review.

Gameplay and symbols

Let’s start with the graphics and design, because here the Hellcatraz slot machine remains unique. The game features pixel art graphics with animations reminiscent of 8-bit games. The focus is on a prison clearly inspired by the legendary Alcatraz. The main characters are a prisoner and a police officer. It’s amazing how the developer managed to combine the retro style with the prison setting while creating a fun atmosphere.

Before you start playing, you can choose between high volatility or very high volatility modes. In the first mode, the hidden symbols are revealed synchronously. In the second mode, the risk increases and the symbols are revealed randomly.

To win, you must collect 3 to 6 identical symbols on one of the 46,656 paylines. Before each spin, you can choose your bet size from $0.10 to $20 per spin. All wins must start from the leftmost reel.

The highest multipliers are provided by the police officer and prisoner symbols. Meanwhile, the wild symbol helps to form winning combinations.

The medium-paying symbols are the shark, the badge, and the handcuffs. The low-paying symbols are represented by cards of different colors. These form the basis of regular wins.

Features and bonuses

Hellcatraz’s bonus features made it one of the best on the market. These features are what attracted the attention of experienced gamers.

Wild

The Wild symbol allows you to collect more winning combinations by substituting for other symbols on the game board. The Wild symbol is present in both the base and bonus games.

Mystery Reveal Function

From time to time, symbols with a question mark appear on the reels. They open synchronously and transform into a single type of symbol, allowing you to collect more winning combinations and big payouts. These symbols also provide the keys to the prisoners’ cells.

Free tours

To trigger the free spins round, you need to collect 2000 keys, which fall from symbols with a question mark. You’ll receive 5 initial spins with the option to increase them. During the bonus round, the Mystery Reveal feature will be activated on each spin, significantly increasing your winning potential.

Cascade Drums

The winning symbols will be removed from the game board and new ones will take their place. As a result, you only pay for one spin, but you have the chance to collect an entire winning streak.

Bonus Buy

You can activate the free spins round instantly. To do so, you will need to place 200 bets.
