Dolphin’s Jewels RTP – Be aware of this!

You might find this hard to believe but depending on which online casino you are playing at, Dolphin’s Jewels's RTP may vary. Your odds of winning might vary even if you play the exact same game across two online casinos.

Your money will disappear much faster at an unreliable casino instead of if you were at the right platform. Here’s why.

On the lower side, Dolphin’s Jewels comes with an RTP of 94.19% and at its best, the RTP can reach 96.26%

This is because Dolphin’s Jewels has something called 'RTP ranges, giving the casino the ability to adjust the chances of winning using changes in their terms and regulations.

It’s quite common for new slot machines to have RTP ranges RTP ranges are provided on almost all games created by Nolimit City, the creators of the slot Dolphin’s Jewels.

Most other gambling platforms follow a similar approach.

Trying your hand at blackjack with adjusted guidelines is comparable to how RTP ranges work in a slot machine. In specific casinos, if both the dealer and the player get 18, the round ends in a push and the player’s money is returned. Meanwhile, at different casinos, their rules say the dealer wins when both have 18.

It’s obviously better to play blackjack where you get your original stake back when both you and the dealer have 18 instead of choosing one where the dealer takes your bet when the situation is the same.

Everything happens in the cards visible on the table, which makes it easy to see as you play blackjack. As you play a slot game, this becomes much more complicated since everything is controlled by math happening behind eye-catching visuals. Playing the good RTP version of Dolphin’s Jewels, which raises your chances of success by as much as 2.07% as opposed to the bad RTP, is why it’s so important to recognize this.

How big a difference does the RTP make?

Dolphin’s Jewels is capable of an RTP as favorable as 96.26% in its best version and as low as 94.19% in the worst version of the game. It’s much more significant than it looks initially when you first look at it.

What truly matters is not about the RTP, but it’s the House Edge, meaning how much the casino on average wins on every spin. The casino's edge is 100% less RTP, i.e., 100% - 96.26% = 3.74% for the advantageous version while the bad version is 100% - 94.19% = 5.81% in the bad version.

By analyzing the numbers 3.74% compared to 5.81%, we can see that the difference is considerably bigger.

To explain this concept further, we’ll convert $100 into the average spins $100 can yield according to the good RTP and the bad RTP.

Assume you’re betting $1 per spin, and you put $100 into your account in the internet casino. Playing the good RTP version of Dolphin’s Jewels, you would achieve on average 2674 spins before you run out of money. $100/3.74% = 2674 total spins is the equation for calculating this.

Every spin on an online slot takes around 3 seconds demonstrating that using 2674 spins, you could enjoy 2 hours of gambling on average.

Now let’s say you find yourself playing on an online gambling platform where the game uses the bad RTP version. At this online casino you will only get 1721 spins. $100/5.81% = 1721 is the calculation in this example.

A single spin lasts about 3 seconds, showing that 1721 total spins will last you approximately 1.5 of gambling entertainment.

Under normal circumstances your bankroll will shrink at more than 40% the usual speed! Your ability to win real money when you play Dolphin’s Jewels are far better in a casino offering high RTP.

How do you know which RTP version a casino has?

You can confirm using your own methods to ensure you’re gambling in a venue with the best version of Dolphin’s Jewels.

To begin, access your casino account by logging in and check that you're playing the real-money mode and then open Dolphin’s Jewels on the platform. The maximum RTP level at 96.26% will be shown if you skip logging in or if you’re in fun mode. Only in real money mode you’re able to check the percentage payout in use at the casino.

When you’re already logged in and in the real-money environment, you launch the game, and then select the game information or settings menu. You’ll need to browse a few sections to look for wording like a sentence reading 'The theoretical RTP of this game is...' or a similar statement. Once you find that sentence you will see either 96.26% or 94.19% instead.

Since the game comes with a bonus buy feature, it’s possible to see some other RTP numbers, as that feature often includes an independent RTP, but it’s normally quite close to the standard RTP of the game. If the casino utilizes the good RTP setting, it should be close to 96.26%, and when the casino uses the bad RTP version, it will be set at 94.19%.

How to win in Dolphin’s Jewels?

At this point, you know a lot about the game and played around with the demo but we still haven’t answered the ultimate question “How do you secure wins in Dolphin’s Jewels?” It’s apparent that RTP holds the most significance when it comes to winning probabilities yet in the case of Dolphin’s Jewels the RTP doesn’t change.

It’s apparent that RTP holds the most significance when it comes to winning probabilities but specifically in Dolphin’s Jewels the RTP stays the same. What this indicates is sadly you have little control to impact your chances of success in this game.

What you can do to increase your likelihood of winning is ensuring that you are playing that provides strong bonus incentives. When using a casino bonus it’s necessary to be aware of the bonus rules.

The primary factor to verify is the wagering requirements. The wagering should be kept low and preferably under 30x. When the playthrough exceeds 30x you should consider passing on the bonus offer.

Be wary of platforms that ask you to wager both your deposit and your bonus as this doubles the wagering requirement and devalues the bonus significantly. The terms and conditions must include the wagering requirements in a format like "You must wager the bonus 30x" or something similar.

Keep in mind that a number of betting sites don’t permit any withdrawals any winnings associated with the bonus. Some gambling sites advertise this as a "bonus with no wagering requirements" which gives the impression of a fantastic bonus but in truth, it’s not that rewarding. What this really means is that the value of the bonus is far less than what is advertised. While it may offer more than nothing, don’t be misled by the big numbers.

In the world of online gambling promotions, the more enticing a bonus appears, the more cautious you should become.

With that in mind, most casino bonuses offer a small return, but the returns are typically insignificant, since, in the end, the house always has the advantage.

Dolphin’s Jewels Max Win

The Dolphin’s Jewels top prize is 15000x. To clarify if you make a single $1 bet the highest win the slot can pay out comes out as $15000.

A maximum win of 15000x is impressive and is better than many slots out there yet it falls short of the best available.

If a really high max win is important to you, you should play Dr. Rock & The Riff Reactor with a 50000x max win or Gladiator Road To Rome which offers players a max win of 150000x.

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

We’ve gone over many details of Dolphin’s Jewels, but we still need to address its downsides.

Here’s the Dolphin’s Jewels Great.com verdict:

• We don't love when slots have different RTP ranges based on where you're playing. Having identical-looking versions of a game with different odds is misleading that visually match but negatively impact the potential for a profitable outcome.
  
  Many game providers continue to use RTP ranges, and many online casinos obscure when it comes to RTP details. Most casinos fail to educate players on RTP, leaving players unaware of how RTP affects them.
  
  

• The biggest jackpot within Dolphin’s Jewels has a limit of 15000. This is great, no doubt, however, we get more excited by options promising life-changing prizes. A max win of 50,000x or more adds more thrill to the experience to every spin.
  
  

Think of playing a slot as though you’re enjoying a movie — it’s about the thrill, not only the result. What delights an individual might bore another — what sparks joy differs for each person. Each person feels about games in a personal way — what excites you may not excite every gamer.
