Starburst XXXtreme is not only a rare new slot because of its highly volatile setting and potentially record-breaking max win.
NetEnt has not released different Return to Player versions of this slot, which goes against the current trend of new slot games with multiple RTP configurations.
Instead, the Starburst XXXtreme RTP varies between 96.26% and 96.45%, depending on your betting strategy.
Some casinos have decided to opt out and not offer this slot in their game lobbies as they don’t want to risk paying the high max win to some lucky player, but CasinoWizard is here to guide you towards the finest online casinos that do so.
Why RTP is important when playing slots
Whether we like it or not, the Return to Player, or RTP, of a slot significantly impacts a lot of crucial elements that come with playing slots.
The RTP is another term for the average percentage that a slot pays back for each stake. So, when a slot has a 96% RTP, it will pay back, on average, 96p for each pound staked. As you can imagine, the higher the RTP, the better it is for you, the player, as this will result in:
More spins before your money runs out
More spins = more chances to win
Increased playing time for the player
More value for money for the player
A lower profit margin for the casino
History of RTP and online slots
In the “old days”, all online slots had a default RTP, meaning the Return to Player was the same for each slot, no matter which online casino you played it in. However, since around 2020, due to regulations, increased Gambling Taxes and rising costs, online casinos started pressuring slot providers to release slots with different RTP configurations.
In effect, the online casino now had a choice: it was now able to offer its players a lower-paying RTP version. You could be playing a specific slot with a 96% RTP at casino A, and play the same slot with a 94% RTP at casino B, without even knowing it. The slot may look and feel the same, but the maths model underneath, which is the heart and soul of a slot, may be different, with all the negative consequences that come with it.
An example in real numbers
To illustrate the difference between playing a high-RTP slot versus playing the same slot but with a lower RTP, we have done some calculations.
Let’s take, as an example, one of the most popular online slots ever made: Book of Dead by Play’n GO. It has five possible RTP configurations: 84.18%, 87.25%, 91.25%, 94.25%, and 96.21%. Of course, other slots have different payout percentages, so results will vary.
We have calculated for Book of Dead, per RTP configuration, how many spins it takes to run out of money, based on theoretical losses (house edge) per spin, a starting balance of £100 and a stake of £1 per spin.
Book of Dead RTP
Theoretical Playtime
House Edge
96.21%
2,612 spins
3.79%
94.25%
1,721 spins
5.75%
91.25%
1,131 spins
8,75%
87.25%
776 spins
12.75%
84.18%
625 spins
15.82%
As you can see in our calculations, there are huge differences in the number of spins when you compare the different RTP configurations. The difference between the 96.21% RTP and the 94.25% RTP version is over 900 spins!
Conclusion
Playing with a higher Return to Player increases your chances of winning and playing time. So, when you want to play an online slot, always try to find a casino that offers it at the highest payout setting.

Keep in mind that the XXXtreme spins remain active until you deactivate them.
The craziest part of all? You can win up to 200,000x your stake per spin.
You can bet 10p up to £2 (aged 18-24) and £5 (aged 25+) per spin. In other words, you can win a cool £1 million with a £5 bet.
What is the maximum win on the Starburst XXXtreme slot?
The Starburst Wild symbols, combined with the highest multipliers, can bring you insanely large wins.
Since the Starburst Wild multipliers can reach up to 150x each, several ways and combinations can get you up to the max win of 200.000x your stake, nestling Starburst XXXtreme comfortably in the higher regions of our top 10 list of highest max win slots.
For example, enough max multipliers combined with the stacked Bars or 7´s and with Re-Spins will get you there.
