Hellcatraz RTP – Be aware of this!

This might be hard to believe but based on the online casino you’re playing on, the return to player for Hellcatraz may change. In other words, the same slot can be played at two different online casinos, although the RTP may vary between them.

When you gamble at a bad online casino, you risk losing real money more quickly than if you were gambling at the right casino. Allow me to explain.

The lower RTP for Hellcatraz is 96.46% and at its best, the RTP can reach 96.88%

It’s all because Hellcatraz incorporates something called 'RTP ranges,' that enables casinos to modify players' odds of winning through tweaks in their stated conditions.

It’s relatively standard for modern slot games to include range-based RTPs Various RTP levels are included throughout a large portion of their games designed by Relax Gaming, the studio behind Hellcatraz.

Many other online gaming companies follow a similar approach.

A blackjack session following different rules resembles how RTP ranges work in a slot machine. In specific gambling establishments, the player gets their money back if both the dealer and player hit 18 as it’s treated as a push. On the other hand, in some establishments, the dealer takes the win under those circumstances.

It makes more sense to play blackjack where you get your original stake back if you and the dealer both have 18 than gambling in one where your money is lost under the same circumstances.

When playing blackjack this becomes obvious, because all events happens through the cards visible on the table in front of you. When playing a slot game, things are much harder to notice because all the events happens in math behind entertaining graphics. That’s why it’s so important to confirm you’re playing the favorable RTP setting of Hellcatraz that increases your likelihood of success by as much as 0.42% versus the inferior RTP.

How big a difference does the RTP make?

The premium version of Hellcatraz has an RTP of 96.88%, and the lowest-quality version of the game has a return-to-player rate of 96.46%. This is way bigger than it might seem when viewed initially.

What the House Edge shows, referring to how much the casino earns per spin on average, is what’s truly important, not the focus on RTP. To find the house edge, you subtract RTP from 100%, i.e. 100% - 96.88% = 3.12% in the better RTP version and the bad configuration is 100% - 96.46% = 3.54% in the worse setup.

The difference we observe in the numbers 3.12% alongside 3.54% is significantly greater, as we observe.

To shed more light on this, let’s transform $100 into the spins $100 would buy calculated using the higher and lower RTP rates.

When you load $100 into the casino in an internet casino and wager $1 per spin, let’s analyze the results. You would average 3205 spins until you exhaust your funds if you choose the good RTP version of Hellcatraz. The math behind this equals $100/3.12% = 3205 spins in total.

The duration of an average slot spin is 3 seconds which means that given 3205 spins, you’d have about 2.5 hours of gameplay.

Now think about it this way you find yourself playing at a casino playing the less favorable version of the game. 2825 total spins is all that you’ll get in this situation. Now, this is calculated as $100/3.54% = 2825 spins.

Each round of spinning takes 3 seconds, which implies that 2825 spins can extend to nearly 2.5 of gaming enjoyment.

You’ll deplete your balance more than 20% faster ordinarily This translates to fewer opportunities for securing a major prize!

How do you know which RTP version a casino has?

You’re able to confirm using your own methods to verify you’re choosing an online casino offering the highest RTP version of Hellcatraz.

Initially, enter your account at the online casino and check that you're playing the real-money mode and from there, play Hellcatraz. The top RTP configuration equal to 96.88% is consistently displayed when you’re not signed in or you are playing with fun money. The RTP setting that’s active in the casino is only visible in the real money setting.

When you’re already logged in and in real-cash mode, you open the slot, and then select the menu or game info section. You’ll be required to browse a few sections to look for wording like the line 'The theoretical RTP of this game is...' or an analogous sentence. Once you spot that sentence you can see the percentage 96.88% or 96.46% instead.

Since the game has a bonus buy feature, you can also find some other RTP numbers, it’s because that feature often has its own RTP but it’s usually very similar to the game’s default RTP. If it’s around 96.88% you can be confident that the favorable RTP version is in use, but should the percentage be around 96.46%, you can conclude that the casino is using the worse RTP option.

How to win in Hellcatraz?

So far, you’ve understood the key features of this game and experimented with its demo mode but we’ve yet to address the most pressing question “How can you improve your chances of winning in Hellcatraz?” It’s evident that RTP is the most important factor in determining your chances of winning however, for Hellcatraz the RTP is set and constant.

It’s evident that RTP is the most important factor when it comes to winning probabilities however, when it comes to Hellcatraz the RTP is set and constant. This means that regrettably you’re unable to do much to influence your chances in this game.

Something you can consider to better your odds is ensuring that you are playing at a site with excellent bonus options. If you decide to use a bonus it’s crucial to know the rules and requirements of the bonus.

The primary factor to verify is the wagering requirements. It’s important to ensure the wagering criteria are minimal and are best when kept under 30x. If the requirement is higher than 30x it’s often a good idea to avoid the bonus.

Watch out for casinos asking you to play through both the deposit and the bonus as it significantly raises the wagering demands and drastically lowers the bonus’s appeal. The casino should provide clear information about wagering requirements as part of the casino’s terms generally expressed as "You are required to wager the bonus 30 times" or a similar rule.

One more thing to consider is that certain casinos restrict you from withdrawing the bonus balance under any circumstances. Some gambling sites advertise this as a "no wagering bonus" which appears highly attractive but in truth, it’s not that rewarding. In practice, the actual value of the bonus is much lower than it initially seems. It might still be preferable to having no bonus but don’t be deceived by impressive-looking numbers.

When it comes to online casino bonuses, the more exciting the offer appears, the more skeptical you should be.

With that in mind, most casino bonuses offer a small return, but the returns are typically insignificant, and in most cases, the casino ends up profiting over time.

Hellcatraz Great.com Verdict - What’s Bad About this Slot?

We have covered many considerations for players who enjoy Hellcatraz, but we haven't yet talked about the negative points of Hellcatraz.

Here’s the Hellcatraz Great.com verdict:

• We’re not too fond of the inconsistency in RTP settings within the same slot at different casinos. It’s deceptive to have multiple versions of the same game that look identical but secretly reduce the potential for a profitable outcome.
  
  Sadly, most game providers follow this practice, and online casinos often make it difficult for players to access RTP settings. Many online casinos neglect to explain RTP, making it difficult for users to grasp why RTP matters.
  
  

• Hellcatraz comes with a maximum win capped at 51840. It’s decent, but our preference is for games that provide more substantial prize opportunities. A max win of 50,000x or more brings an extra layer of excitement to the fun.
  
  

Picture yourself playing a slot similar to experiencing a film — it’s all about the experience, beyond just the rewards. Some may think it’s wonderful, others might not appreciate it, since what brings joy varies from person to person. The way you view when it comes to this game, will likely be highly subjective for you. We’re focused on reviewing using objective criteria, still, you can give a shot to the demo version of Hellcatraz above and decide for yourself.
