The theme is excellent and brings us back to the golden age of 8-bit and 16-bit video games on Sega and Nintendo consoles. Who isn’t familiar with the island of Alcatraz, where criminals were imprisoned until 1963? Who hasn’t seen the famous movie Escape from Alcatraz, starring Clint Eastwood? Or Dirty Harry, where this renowned island is part of the scene?

Casino Hipster verdict: Smokin!
In this game, everything takes place on the island of Hellcatraz. Strangely enough, the protagonists are a copper and a prison director (or a mayor).
Escaping is very difficult. After all, you also have many sharks and coastguards.
Relax Gaming has done another great job, and they are doing it more and more lately. As of now, we need to take Relax Gaming very seriously! In a positive sense.
Hellcatraz is very volatile. Relax Gaming does not officially indicate it, but research shows that…
The maximum bet is “only” $€25, which is pretty low for Relax Gaming standards. It confirms that this slot can pay out enormously! Well, above the million! HELL!
Hellcatraz has 6 reels with 6 rows of symbols. The win all ways mechanism applies: so there are 46,656 ways to win (6x6x6x6x6x6=46,656).
The Avalanche (Cascading) mechanism is played here, where you get a free re-spin after every winning combo. The winning symbols make way for new symbols.
You don’t get these straight away, though. There is a counter, and only when the counter is at zero, you will see into which symbol the mystery symbol changes to.
There are two different “modes” or game variants you can choose from:
In the Mixed Mode, at least two different mystery symbols with different counters appear on the reels. If one is unlocked, there are eventually fewer mystery symbols that unfold.
If you choose Slotdown Mode, then one mystery symbol is active. If it is unlocked, there are many more unlocked symbols, with, of course, more chances of a lucrative combo.
To activate the free spins bonus, you need to collect 2,000 keys during the base game. Some spin, you will receive one key, sometimes more. Be prepared to play for a long time before you have reached your goal.
The alternative is to buy the bonus feature, at the cost of 200 times the bet.
You get 5 free spins. If you manage to open a golden safe, which opens automatically after two consecutive winning combos, you get a free spin.
The main advantage of the free spins (over the main game) is that the mystery symbols open after every spin.
The RTP is 96.46% when the game is played in the Slotdown Mode. In the Mixed Mode, it is 96.30%.
In the Buy a Bonus Feature, the payout percentage is a fantastic 96.83%.
Anyway, Relax Gaming usually delivers slots with sound payout percentages!
Relax Gaming is always mysterious about what the variance is.
In the end, you’ll have to do it with my judgement. Based on the unofficial maximum prize of over 50,000x, it is safe to assume that the variance is high.
My assumption is reinforced by the relatively low maximum bet you can make ($€25) and the considerably high price you pay for the free spins (200x the original bet).
Put it in simple words. I expect that prizes of 1,000x the bet or higher are realistic.
Players who like slots with a saving mechanism can enjoy it once again!
The theme is very original and well thought. If the famous island of Alcatraz appeals to you, this slot will appeal to you, no doubt!
You have to bring a lot of money with you, and be comfortable with the risks involved. Otherwise, it makes no sense to play this slot.
You can find Hellcatraz at all the best Relax Gaming casinos, where you can play this entertaining online slot for free or for real money.
