Hellcatraz Slot Overview

Hellcatraz is a new casino slot from Relax Gaming on the infamous American prison island Alcatraz. This game takes us back to when there were still prisoners in the building, which today is a museum. The game has pixelated graphics, reminiscent of an old 8-bit video game played on consoles like the Nintendo Entertainment System, which was extremely popular in the late 80s.

You visit Alcatraz at sunset, and you’ll find sharks, handcuffs, a police officer, and a villain, among others. The villain is doing his best to try to escape and runs off to the free spins whenever he manages to collect enough keys. The 6x6 grid has Mystery Symbols that will explode and reveal the same symbol when you perform cascading wins. The Mystery Symbols have different counters, depending on if you’re playing the highly volatile Mixed Mode or the super highly volatile Lockdown Mode. No matter which one you choose, you can score the incredible max win of 51,840X the bet.

Hellcatraz Slot Information

The sun is setting on the prison island Alcatraz in the bay next to San Francisco. To the left of the island is the Golden Gate Bridge, and to the right are skyscrapers in the distance. The island has rocks all around it and a lighthouse right next to it. The 6 black reels are framed by brown bricks and stand tall in the middle of the island. To make a win in prison, you need to land at least 3 of the same symbols on adjacent reels, starting with the first reel to the left. The game is available on mobile phones, notepads, and desktop computers.

You’ll find several interesting symbols in Hellcatraz. The lower-paying ones are a purple diamond, a green four-leaf clover, a red heart, and a yellow star. They all pay the same, giving you 0.4X the bet for a 6-of-a-kind win. The higher-paying symbols are handcuffs, guard badge, shark, prisoner, and policeman. These five characters award between 0.6X and 2X the bet for a win containing 6 symbols. The Wild Symbol substitutes all mentioned symbols but not the Mystery Symbol. There is no Scatter Symbol; the free spins feature is instead triggered by collecting keys.

Wild Symbol

The Wild Symbol is an orange W. It substitutes all regular-paying symbols in making wins.

Cascading Wins

Every time you make a win, the winning symbols will disappear, and the remaining symbols fall to the bottom while new ones are added from above. If you’re able to make a new win, those involved symbols will also vanish. The cascades continue until you can’t make any more wins, and they all belong to the same spin.

Choose Mode

Before you can start spinning Hellcatraz, you get to choose if you want to play the highly volatile Mixed Mode or the Lockdown Mode with super high volatility. The Mixed Mode has an RTP of 96.30%, and the Mystery Symbols will have two independent counter values. The Lockdown Mode has a slightly higher RTP of 96.46%, and all Mystery Symbols will have the same value on each spin.

Mystery Reveal Feature

The Mystery Symbol is a wooden box with a number between 1 and 5. For every cascade, the number decreases by 1. Whenever a Mystery Symbol reaches 0, it will reveal a symbol. All Mystery Symbols revealing symbols at the same time reveal the same type of symbol. Playing the Lockdown Mode will always reveal all present Mystery Symbols simultaneously, while the Mixed Mode has two independent counter values. At some times, the two Mixed Mode values show the same number.

Super Free Spins

There are no regular free spins in Hellcatraz, just one Super Free Spins feature that can bring big wins. Small Key Symbols can land on top of any symbol in the base game. Each key is collected on a meter to the left of the reels, awarding between 1 and 10 points. Reaching 2000 points triggers the Super Free Spins.

The feature starts with 5 spins, and the Mystery Symbols don’t have a number but reveal a symbol as soon as they land. A Golden Mystery Symbol with a counter number of 2 is also added to the reels. Whenever it lands, it’s opened by making two cascades. The Golden Mystery Symbol reveals a random symbol and awards an extra spin whenever it’s opened.

Bonus Buy

You can either buy the complete Super Free Spins or purchase the missing number of keys to trigger the feature. Buying the full feature costs 200X the bet, and each key costs 0.1X the bet size. Buying 2000 keys will cost you the same as buying the full feature. If you have collected 1000 keys and want to buy the remaining ones, you’ll need to pay 100X the bet.

The RTP of the Bonus Buy feature is 96.83%

Hellcatraz Slot Conclusion

Hellcatraz is a game with quite innovative features. Although it has a retro look with pixelated characters, it manages to give a modern look. The graphics can be compared to Push Gaming’s Fat Rabbit and Fat Banker. Wazdan’s Lucky 9 is another pixelated slot, but its square graphics resemble more modern video games like Minecraft.

The Mystery Symbols make the game much more interesting since you need to make between one and five cascades to reveal them. If you play in Lockdown Mode, which offers a slightly better RTP, all Mystery Symbols are revealed on the same cascade. This is also the most volatile of the modes. The Mixed Mode will give the Mystery Symbols two different counter numbers, although they will be the same on some spins. The Mixed Mode lowers the volatility a bit, but it’s still high.

You need to collect 2000 Key Symbols to enter the Super Free Spins. This could be seen as both a gift and a curse. Since the feature isn’t triggered by Scatter Symbols, you’re not going to be lucky and activate it after just a few spins. On the other hand, you’ll probably not be super unlucky and have to wait for ages to activate it, either.

The Super Free Spins can bring very big wins. Buying the feature sets you back 200X the bet for 5 starting spins. The average win when buying the Free Spins is 193.66X the bet, but you should know that the winnings can vary significantly between spins.

Hellcatraz from Relax Gaming takes place on Alcatraz Island, where Mystery Symbols can be opened by making consecutive wins.
