Harpoon Heist RTP – Be aware of this!

Your likelihood of winning on Harpoon Heist will change from one online casino to another, which could surprise you. You heard that right, the exact same online slot can be played at two different casinos, although the RTP are not guaranteed to be the same.

You could lose everything in less time at a bad casino compared to if you were at the right platform. I’ll explain this for you.

Harpoon Heist comes equipped with an advantageous RTP option of 96.01% but also includes a less favorable RTP version of 87%.

The reason is that Harpoon Heist features something known as 'RTP ranges,' providing the casino with a way to alter the probability of success through adjustments to their terms and conditions.

It's not uncommon for freshly launched slot games to have RTP ranges A variety of RTP levels exist throughout a large portion of their games developed by Light & Wonder, the developer of Harpoon Heist.

The situation is similar for many of the top gaming studios.

You can think of RTP ranges as part of slot gameplay to a round of blackjack under modified rules. At certain casinos, when the dealer and the player tie with 18, it counts as a standoff and the player gets their money back. In other casinos, the dealer is declared the winner if both sides reach 18.

Being the losing party in a casino in the event of a tie at 18 is far worse than playing blackjack at a venue that pays you back your bet in the exact same scenario.

In the game of blackjack this becomes obvious, because all the action takes place in the cards clearly displayed in front of you. As you play a slot game, it’s trickier to figure out since everything operates via mathematical calculations behind entertaining graphics. That’s why it’s essential to know that you are playing the high RTP version of Harpoon Heist which increases your win percentage up to 9.01% over the less favorable RTP.

How big a difference does the RTP make?

The highest-quality version of Harpoon Heist has an RTP of 96.01%, and the least optimal version has an RTP of 87%. It’s much more significant than it may appear upon an initial look.

The casino's expected profit, which represents how much the casino wins on every spin, is the crucial element, not the RTP. The house profit is 100% minus the RTP rate, that equals 100% - 96.01% = 3.99% in the good version while the bad version is 100% - 87% = 13% in the bad version.

The gap between the values 3.99% versus 13% is much bigger, as we can tell.

To shed more light on this, we are able to identify how often you can spin $100 will allow you to make according to the version you’ve selected to play.

Let’s assume you’re betting $1 per spin, and you deposit $100 in a virtual casino. You are expected to achieve 2506 spins until you exhaust your funds if you play the good RTP version of Harpoon Heist. $100/3.99% = 2506 total spins is the formula used to find this.

Online slot spins usually take 3 seconds to complete which means that considering 2506 spins, you can gamble for roughly 2 hours.

Let’s then say hypothetically you find yourself playing within a casino where you’re stuck with the bad RTP setup. 769 spins on average is the entirety of what you’ll get at this online casino. Under these conditions, this is calculated as $100/13% = 769 spins on average.

An average spin on a slot machine lasts 3 seconds demonstrating that using 769 spins, you can gamble for roughly 0.5 hours.

Under normal circumstances your funds will disappear over 70% faster than usual! This translates to considerably fewer chances for securing a major prize!

How do you know which RTP version a casino has?

You can verify for yourself to ensure you’re playing in a casino that has the top version of Harpoon Heist.

First, access your casino account by logging in and make sure you're playing the real money settings and after that, load up the game Harpoon Heist. If you haven’t signed into your account, or if you’re using practice funds, it will default to the highest RTP setting equal to 96.01%. The return-to-player percentage the casino uses can only be seen when in real money mode.

You’ll need to check for the game menu or slot information icons while engaged with Harpoon Heist if you’re logged into your casino account and gambling in real-money mode. In this case, you’ll have to browse a few sections to search for a statement like “The theoretical RTP of this game is…” or an equivalent phrase. It will show you either the 96.01% or the RTP set at 87% after you identify the sentence.

You might notice alternate RTP numbers since a bonus buy option is present in the game, that typically comes with its own RTP, but is typically very close to the game’s configured RTP. When the better RTP version is in effect, it will be close to 96.01%, but when the casino operates with the bad version, the percentage will be around 87%.

How to win in Harpoon Heist?

Up to now, you’ve gained a deeper understanding of this game and you have hopefully tried the game's demo version but we still haven’t answered the question “How do you achieve victory in Harpoon Heist?” It’s apparent that RTP holds the most significance for calculating your odds of success however, for Harpoon Heist the RTP stays the same.

Well, we have established that RTP is the most important factor for improving your chances of winning at casino games however, in Harpoon Heist, we’ve found there is only one RTP level. As a result it’s sad that your options for change are slim to enhance your chances of winning.

A step you can take to improve your chances involves confirming you’re playing at a casino offering a great bonus. When opting for a casino bonus it’s vital to read and comprehend the relevant terms and conditions.

The initial aspect to examine is the wagering requirements. It should be as low as possible and should not exceed 30x. When the playthrough condition surpasses 30x you should probably avoid the bonus altogether.

Be cautious of platforms requiring you to wager the deposit and bonus together since it increases the wagering by twofold and greatly reduces the bonus’s value. The terms and conditions must include the wagering requirements as "You need to wager the bonus amount 30x" or an equivalent condition.

A key point to remember is that certain casinos restrict you from withdrawing your bonus money at all. Many platforms label this as a "no wagering bonus" making it look very appealing but in practice, it’s not as good as it seems. In most cases, this means that the bonus is worth considerably lower than it initially appears. Though it’s still better than no offer, don’t fall for bonuses that seem too good to be true.

For casino promotional offers, the more appealing the deal looks, the more you should analyze the fine print.

Bearing this in mind, some online casino promotions have minor benefits, though the benefits are generally minor, and more often than not, the casino will find a way to win in the long run.

Harpoon Heist Max Win

The slot Harpoon Heist max win can reach 10000x. What this implies is if you make a spin costing $1 the largest payout available in the game amounts to $10000.

10000x represents a large max win and it beats most slots out there but it's not reaching the highest wins you can find.

If a really high max win is important to you, you could play Fruit Twist (Oryx) with a max win of 100000x or Cash Stax which offers players a max win of 250000x.

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

While we’ve covered a lot about Harpoon Heist, we haven’t discussed its weaker points.

Here’s the Harpoon Heist Great.com verdict:

• We don't love when slots use various RTPs based on the casino. The presence of various versions of this game that have no visible differences but make winning significantly harder feels like cheating and deception toward the players.
  
  Sadly, most game providers follow this practice, and it’s challenging for players to find to locate the actual RTP details. Most casinos fail to educate players on RTP, contributing to player confusion about RTP’s role.
  
  

• Players won’t find an option in Harpoon Heist activating the Bonus Buy feature. This feature is widely favored nowadays, and a game that lacks it fails to capture the same excitement.
  
  

• Harpoon Heist offers 10000 with a spin. For gamblers looking for massive potential, this one falls short in terms of payouts, considering there are games with far more lucrative top prizes. The higher the win potential, the greater the thrill a game can bring.
  
  

• The developer behind this game is Light & Wonder this game, however, it’s one of the lesser-known providers in the industry. Consequently, the game won’t be as widely accessible in as many casinos like the titles developed by the top slot game creators.
  
  

Besides what we've discussed, don’t forget that enjoying a slot is much like how we experience a movie. What excites someone could seem dull to another — joy isn’t one-size-fits-all. Your opinion when it comes to this game depends largely by your unique preferences.
