Bonus Features in Hellcatraz
It’s not just the design in the Hellcatraz slot that’s a little unusual. The gameplay is too, starting with the game engine. You’ll also see cascading reels which can in turn reveal special mystery symbols. There’s also a free spins round which, once again, is triggered in an unorthodox manner. We’ll start by looking at the game engine set up.
Cascading Reels feature
A winning combination results in a cascade where the successful symbols are removed and new ones replace them. The cascades keep on coming until no more new wins are formed.
Mystery Reveal feature
Mystery symbols which appear in the form of a number can land on any spin. With each cascade, their number drops by 1. When it reaches 0, the mystery symbol is revealed.
At the start of the game you’ll have the option of picking Lockdown Mode or Mixed Mode. In the former, all the Mystery Symbols have the same number. Choose the latter and there are independent counter numbers in play.
Super Free Spins feature
You’ll see keys appear overlaid on top of standard symbols. These can award between 1 and 10 keys. After any keys have been collected, the symbols act as normal. Instead of landing scatter or bonus symbols, collecting keys is how you trigger the main feature in Hellcatraz.
The Super Free Spins feature is activated once you have collected 2,000 keys. You begin with 5 free spins. The Mystery Symbols are active in the bonus round. You don’t need to land successive cascades to open them during the free spins though.
Also joining the action during the free spins round are Golden Mystery Symbols. If there are 2 of these on the reels and you go on to land 2 or more cascades, you’ll get 2 more free spins added to your total.
There are a couple of options here. You can pay 200 x your total stake and buy the Super Free Spins feature directly. This doesn’t have any effect on how many keys you have collected. They remain the same and you’ll start adding to the same number when the free spins are over.
Alternatively, you can use up the keys you have already collected and then top up by paying extra. The amount you have to pay varies depending on how many keys you have already collected. The Buy feature isn’t available in the UK due to regulations by the UK Gambling Commission.
Hellcatraz Slot RTP, Details and Wager Limits
The Hellcatraz slot is played using a 6x6 grid. Winning combinations are formed by landing matching symbols on adjoining reels, starting from reel 1. There are 46,656 ways to land a winner. And no, it's not a Megaways slot.
You can play Hellcatraz at stake levels that start at just 10p per spin. This rises to a maximum of £25 per spin for the Harry Grout-style Mr Bigs if the world.
The RTP is a reasonable 96.46%. This rises to an even better 96.83% if you opt to buy the feature. The Hellcatraz volatility is exceedingly high. This is a super high variance slot. We’re in 10 out of 10 territory on the volatility stakes. You can expect some length spells where your jail escape plans come to nought. The free spins round can really get the action going though.
The max win is a whopping 51,843.3 times your total stake though. The chances of winning big increase in the Super Free Spins feature. The hit frequency is 19.92% meaning just 1 in 5 spins will result in a winning combination.
Hellcatraz Theme - Audio and Design Features – block, retro visuals look superb
Hellcatraz has the feel of an old school video game. The pixelated imagery is excellent. With the Golden Gate bridge, the San Francisco skyline and the famous Alcatraz Island prison in the background, the front of the screen is guarded by a pair of police boats.
On the reel grid you’ll see lower value diamond, star, heart and clover symbols. More rewarding are the handcuffs, prison officer’s badge, shark, prisoner and officer. The visuals here are excellent and have a lovely retro feel. It works very nicely.
You can play Hellcatraz on desktop, mobile and tablet devices. Despite the 8-bit, 80s inspired graphics, it uses HTML5 technology so can be enjoyed on iOS, Windows and Android powered devices.
Hellcatraz Review Summary – unusual, volatile gameplay and original design combine to explosive effect
The Hellcatraz slot is an unusual game but it’s one that offers something original. That’s true of the game engine, the base game features, the bonus round and the design. The Super Free Spins feature has the potential to be a cracker, especially if you manage to add extra free spins to your original allocation.
A trip to Hellcatraz certainly isn’t one for the faint of heart. The action here is super volatile. It can be a risky proposition for your bankroll but it can deliver some massive rewards. The maximum win of 51,843.3 x stake per spin is worth risking being bad for.
It’s about as far away from a classic fruity as you can imagine but if you fancy trying something different, breaking into Hellcatraz could be the answer. Another slot with similar graphics is ELK Studios’ Flame Busters which offers plenty of bonus features and 5,280 x stake wins on every spin. A second option would be the Street Fighter II: The World Warrior slot by NetEnt which is based on the infamous video game.
❓ What is the Hellcatraz slot RTP?
This varies slightly depending on the round you’re playing. The Hellcatraz return to player rate in the standard game is a solid 96.46%. If you choose to pay to buy the Super Free Spins feature with the Buy feature, this increases to 96.83%.
🥇 What is the Hellcatraz maximum win?
In theory, the potential jackpots on offer from a trip to Hellcatraz prison are absolutely enormous. The maximum win stands at a massive 51,843.3 times your total stake. That sum sounds like it should get you into rather than out of Hellcatraz.
🎰 Does Hellcatraz come with free spins?
Yes, this prison adventure does come with a Super Free Spins feature. It’s triggered in an unusual manner by collecting overlay key symbols. If you don’t want to wait, you can buy the bonus. Either pay 200 x your stake directly or use your collected keys and use cash to top up the rest.
⚡ What is the Hellcatraz volatility?
The virtual prison walls are highly volatile ones. This is a high-risk slot but the upside is the potential it offers to deliver some grandstand rewards. On a scale of 1 of 10, the Hellcatraz variance is a fiery 10.
