Hellcatraz Slot - Play for Real Money or Play the Demo for Free

Introduction

Hellcatraz is an online slot from Relax Gaming with a retro theme that features over 40,000 winning ways and offers a wide betting range that starts at 10p per spin. There are some great bonus features in this slot, including free spins and mystery symbols, along with a generous top prize worth 51,843x.

Theme and Graphics

Hellcatraz from Relax Gaming has a really interesting aesthetic that is sure to appeal to fans of retro gaming. The slot features 8-bit style graphics, like you’d encounter in old school Nintendo games or retro-style games like Hotline Miami, which is pretty unique in today’s slot market.

It resembles Playtech’s Pixel Samurai and Thunderkick’s Flamebusters, and we’d definitely like to see this style represented more in modern slots.

RTP and Variance

The return to player (RTP) of Hellcatraz online slot is 96.46% for lockdown mode (watch out though this is super volatile) and 96.30% for mixed mode. It’s a high-volatility slot, whichever mode you play in, just even more volatile in lockdown!

How to Win

The slot takes place on a 6x6 grid with 46,656 winning ways. To hit winning combinations, you have to match symbols in any position as long as or more of them appear on adjacent reels. The matching symbols have to appear from left to right, though.

The most generous symbol in the game is the police officer. He pays out a prize of 10x your stake when he appears six times across the reels. However, the biggest win you can land while playing Hellcatraz is worth 51,840x your stake.

This is due to the fact that there are plenty of different bonus features in the game, including cascading reels, which cause winning symbols to disappear and new symbols to fall into their places. So, you can land multiple wins on each spin.

Mystery Symbols

There are Mystery Symbols in this slot, but they don’t play out like they do in most slots. Each one is behind a set of bars and has a counter on it. Every time a cascade occurs, the mystery symbols will stay on the reels, and their counters will decrease by 1. When the symbols’ counters reach zero, they display the same symbol.

There are two ways that the Mystery Symbols work, which depends on the Mode you’re playing in.

Mixed Mode

The mystery symbols have different counters on them. For example, some symbol counters start at 3 while others start at 5 on the same spin. Warning - slightly lower RTP.

Lockdown Mode

All mystery symbols on the same spin will show the same counter. This is the “super high volatility” option, as it offers up some very generous payouts. But it can take quite a while for the countdown to reach zero on all symbols, but they’ll all make their reveals at once to help you land some big wins. Warning - slightly higher RTP but very volatile.

There is also the Key Collector Metre, which will trigger the Super Free Spins round if you manage to collect 2000 keys. These keys appear randomly throughout the base game and, although it can take quite a while to collect the keys, using the Buy Feature option allows you to purchase additional keys to get you closer to the Super Free Spins bonus – similar to how it works in Reel Rush 2.

During the Super Free Spins round, there is no countdown on any of the mystery symbols. Since lots of mystery symbols land on the reels on each spin, there really is the potential for you to land some amazing prizes.
