Game Overview
Get your life rafts at the ready as Relax Gaming take us to the rock for an escape of a lifetime in their exciting title Hellcatraz Slot. Quite clearly based on the notorious San Fransisco jail, the game is set over a 6 reel and 6 row format, with a total of 46,656 paylines active on every spin of the reels. Escape from this famous prison and you might just earn yourself a maximum win of 51,843x bet.
Play with the cascading reels mechanic, and 2 different game modes which offer varied levels of volatility. Trigger the free spins feature via the key collection meter, and rack up potentially huge wins with mystery symbols that can land on every spin.
Let’ see if you have what it takes to make the perfect prison break in our full slot review. Alternatively jump straight to our free play demo of Hellcatraz Slot and enjoy unlimited practice spins. This trial mode is accessible on your desktop, tablet, and mobile devices.
Hellcatraz Slot Theme, Stakes, Pays & Symbols
As we mentioned already the game is themed on the legendary slammer Alcatraz and Relax Gaming have opted for a retro approach when bringing the famous jailhouse to the reels. The iconic Golden Gate Bridge can be seen in the background as can the San Fransisco skyline, whilst the reels themselves are cast in the infamous prison.
Upon inspecting the paytable we see the the lower value symbols are made up of the diamond, clubs, heart, and star, with pays ranging from 0.1x, up to 0.4x when wins are formed through them. Higher paying symbols consist of handcuffs, a guards badge, shark, inmate, and prison guard, with a 6 of a kind win paying 0.6x, 0.8x, 1x, 1.2x, and 2x respectively.
The minimum price of play to get into the action on Hellcatraz is just €0.10 a spin, with the maximum stake on the game reaching €25. In total there are 6 playable stake sizes that range from €2.50 down to the minimum bet, this represents good value in our opinion and makes the slot accessible to players with all sized bankrolls.
Hellcatraz Slot Base Game
Before you even take your first spin on Hellcatraz you will need to decide which game mode you would like to play. This will influence the mystery reveal symbols that will land in view on every spin of the reels, and the number that they have on them that ranges from 1 – 5. This number represents how many reel cascades are needed before the symbols will transform into a randomly selected symbol from the paytable.
There are a total of 2 game modes for you to choose from and we have detailed these below so that you can see what the differences are. It’s worth noting that you are able to toggle between modes any time that you like during your gameplay, and this can be down through the mode button that is located to the left-hand side of the reels.
- Mixed Mode – High Volatile: In the mixed mode option the mystery reveal symbols can have two independent counter values, or can both feature the same number.
- Lockdown Mode – Super High Volatile: The lockdown mode will see all mystery reveal symbols carry the same counter value.
Hellcatraz Slot Cascading Reels
As you would have probably worked out from the previous part of the review Hellcatraz makes use of the cascading reels feature, and as we said this is key to bringing the counter numbers down to zero so that they reveal a symbol. This reel mechanic can also be great for hitting a few consecutive wins and adding some extra cash to your balance. This is due to the fact that reel cascades will continue until there are no further winning connections on the reels.
Hellcatraz Free Spin Feature
To enter the free spin feature on Hellcatraz you will need to collect the key symbol that will sometimes appear on normal symbols that land in the base game. When these keys appear they will add between 1 – 10 keys and will fill the key collector meter that is located at the left-hand side of the reels.
For the bonus round to trigger you will need to collect a total of 2000 keys. If this is achieved then you will be awarded with 5 free spins to begin the bonus feature with. Players should note that it is possible to collect the 2000 keys over a number of stakes, if you choose to do this then the feature will be played at an average bet of which the keys were collected.
During the bonus round on Hellcatraz the mystery reveal symbols will again be present, but the really good thing is that you will not need to complete any cascades for them to transform into a symbol from the payable, as they will always land in view with their counter already on zero. So ideally you want to see as many of these symbols land as possible, especially when there are wins of over 50,000x up for grabs.
Additional free spins may also be awarded whilst the bonus is taking place, and this time you will need some assistance from the reel cascades. A mystery reveal symbol with a counter of 2 may appear on the reels, if it does and you hit two consecutive cascades then it will reveal a random symbol and 1 extra free spin.
Hellcatraz Slot Bonus Buy
For those who are playing from a region where it is still possible to buy a bonus round, you will be able to do so on Hellcatraz for 200x your stake. Alternatively if you have collected a number of keys already then you will be given a reduced rate to buy the rest that you require to trigger the free spin bonus. If this option is taken then again the feature will be played at an average bet of which the keys were collected.
Hellcatraz Slot Review Final Thoughts
Hellcatraz is a very cool retro slot that has been well thought through and we absolutely love the theme behind the game. This could have something to do with us being massive fans of the original movie Alcatraz that starred Clint Eastwood as Frank Morris, who was one of three people believed to have escaped the rock, the other two of course being Clarence and John Anglin.
Anyway, back to the matter in hand. There will be a number of players who will instantly think of the slot Flame busters when they see this game, this will largely be down to the fact that they both have a very retro design to them, but Hellcatraz is by far the better slot in our opinion. Give it a try and see if you enjoy it as much as we do.
