Sharing is caring!

Our rating:
  • A great-looking slot with some unique features
  • Change the game mode to alter the mystery symbols
  • Win up to a staggering 51,000x stake payout

Hellcatraz slot is the latest from Relax Gaming and it immediately stands out thanks to its retro design. It reminds me a bit of Wreck it Ralph, the actual game, and I’m really impressed. For those who loved the old video games and don’t want something that just looks like a normal slot machine, this could well be for you.

There are a few features here but before we come onto them, let’s start with the basics. You have a 6×6 reel setup and need to get a winning combination from left to right using the base symbols. These are as follows, ranked in ascending order based on their value:

  • Card Symbols (lowest value)
  • Handcuffs
  • Badge
  • Shark
  • Prisoner
  • Correction Office (highest value)

Hellcatraz Slot Bonuses and Features

Cascading Reels. This works like any other cascading slot whereby winning symbols are removed from the reels so that new ones can fall down, in the same spin, and potentially form another win. This will continue until there are no more wins.

Mystery Reveal. Mystery symbols can land on any spin, displaying a number. With each cascade, the number drops by 1 and when it reaches 0, a mystery symbol is revealed. Lockdown Mode will mean all mystery symbols have the same number, whereas mixed mode means they have different numbers.

Free Spins Bonus. In order to trigger the main bonus in this game you need to collect symbols rather than land the usual scatters. The symbols you’re after are key symbol which can appear on top of regular base symbols. Each symbol can have up to 10 keys on it, and you need a total of 2,000 keys to trigger this bonus. This can take a little while, but on the other hand it’s nice to be able to see your progress as opposed to the bonus being triggered randomly as is normally the base. Changing stake will reset the number of keys. Once you trigger the bonus, you have 5 free spins. Mystery symbols are in play here, but they trigger automatically rather than needing a number of cascades to open them up. You also have golden mystery symbols which can offer you an additional 2 free spins if you land 2 of them and then get 2 cascades with them.

Buy Feature. If you’re outside the UKGC, you can buy the main feature in this game like many other slots also offer these days.

hellcatrax slot rules


Hellcatraz slot from Relax Gaming is a great-looking slot that really feels more like a retro arcade game than a slot machine. The design is fantastic with some great characters and the ability to change modes also works well to make you feel like you’re playing a game. The base game doesn’t offer too much apart from mystery symbols which aren’t normally that helpful, but once you collect enough keys you can play the free spins bonus which makes the symbols much more valuable. In fact, if you’re lucky you can win up to a crazy 51,000x stake for some life-changing money. In short, it’s a great-looking slot that’s fun to play and can offer you some crazy money, but it is highly volatile so just bare that in mind. You can also find some of their other slots here.
