There are certain times when a dated design is no longer a bad thing, and an 8-bit style slot machine is definitely one of those. We’re looking at Hellcatraz, a new slot machine which borrows its graphics style from the arcade games of the 80s, a Relax Gaming release which gives us extreme volatility and big top payouts, along with a theme which is inspired by the toughest prison to escape from, the famous Alcatraz.

Hellcatraz was designed with 6x6 reels and 46,656 paylines, and while its volatility is high or very high (depending on the mode you play in), there is also the chance that you will get from it awesome rewards, of up to 51,840x the stake. Extremely risky to play, but also quite fair with its RTP of up to 96.46%, the slot comes with features such as mystery symbols, collected keys, Super Free Spins and wilds.

Betting and Prizes

You get a betting range between $0.20 and $20. It’s a value that you can select, and then you get all the potential combinations active in exchange.

Once you get to the Super Free Spins, the potential of the game seems to be at its highest, and there are rewards of up to 51,840x the stake that can be paid in a single spin. It’s a huge reward that you can get here, but the chances are not going to be very high that it will actually happen for you.

Even so, we know that the game, while risky for individual players, will do just fine long-term and as an average, since its RTP goes up to 96.46% during its regular spins, and to 96.88% if you buy the bonus feature directly.

Hellcatraz Slot Features

Played on 6x6 reels, the game will form its combinations with 3 or more symbols, landing left to right on consecutive reels. It includes the cascading reels mechanic as well, so a winning combination may very well be followed by additional wins, if the new symbols land where they’re needed.

As you play this game, there is the option to play in either Mixed or Lockdown Mode. The former is High volatility, while the latter is Very High, so it depends on what kind of risk you can take. RTP changes a bit, as will the hit rate.

The wild symbol is the one with the W logo, it’s easy to spot, and it’s useful often enough as a simple substitute.

Mystery symbols show up, but they’re not immediately useful. They have countdowns on them during the regular spins. For several cascades, they are going to act as blocker symbols, which occupy positions on the reels and don’t do anything for you. The Mystery feature is then appreciated, but the countdown is just annoying.

Keys which appear as part of regular symbols will bring 1 to 10 keys in a special meter, the aim being to get to 2,000 keys, so that the Super Free Spins can trigger. There is no requirement for cascades in this mode, so the mystery symbols are used immediately.

Theme & Design

It’s an Alcatraz themed slot machine, where the main characters are the prison guard and the mobster. Other symbols range from sharks, to badges, handcuffs and the four card suits. Scatters and wilds are also used, as are mystery symbols. It’s an 8-bit style design, charming and retro, which should be enjoyable for a lot of players that remember the arcade games of the 80s.


Hellcatraz looks like a very interesting release, a slot machine with retro graphics but modern features, very high volatility, but also top payouts of over 50,000x the stake as a possibility.
