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.

Gameplay and features
Iron Bank is played on a 6-reel and 4-row game panel with 4,096 ways to win.
Bets start at 10p and go up to £2 (aged 18-24) and £5 (aged 25+) per spin.
Base game
Random mystery symbols: Can be added to the reels at the start of any spin. The mystery symbols transform into the same symbol.
Random bonus symbols: 1-3 bonus symbols may be added to the reels during any spin, increasing the free spins’ chance of triggering.
Full reel wilds: Can land on reels 2-5 and have multipliers between x2-x10 that multiply each other when more than one contributes to winning.
Free Spins
Three or more Bonus symbols award one of these three available bonus games:
Mystery symbols: 8 Free spins. A randomly chosen symbol, before each spin, will become the sticky symbol. When they fill an entire reel with sticky symbols, +1 additional Free Spins are added to your spins.
Expanding Wilds: 10 Free Spins. Wilds landing on reels 3 and 4 expand to fill the reel and award a re-spin—any win involving an expanded wild increases the multiplier with +1. The sweet spot happens when two high multipliers keep increasing and is calculated together after each re-spin win.
Multiplier collect: 12 Free Spins. Landing coconut crates across reels 2-5 increases the multiplier meter above those reels. The achieved multiplier is then applied to the wild symbols. After each x3 multiplier has been achieved, +3 additional Free Spins are added to your total spins.
Iron Bank Buy Feature
You can buy the Free Spins bonus game in jurisdictions where it is allowed by paying 100x for your current bet.
Please be advised that players from the United Kingdom cannot buy bonuses.
What is the maximum win on Iron Bank?
The max win on Iron Bank is capped at 49,999x your bet per spin.
We haven’t come across a max win on this slot yet, but there are loads of examples of big wins available on YouTube from casino streamers.
The big wins can be achieved in any of the three Free Spin bonus games, while the “Expanding Wilds” is the most volatile option.
CasinoWizard’s verdict: Iron Bank is a fantastic slot (8 out of 10)
Cooperation between game providers and players is rare, but CasinoWizard welcomes the idea and looks forward to future collaborations. Players can contribute new ideas, features, and concepts that the staff at the game suppliers might not have thought of.
There is quite an entertaining mix in this Iron Bank slot.
The base game has three features and three Free Spins bonus games with various functions and volatility levels.
The outcome from the Free Spins can be frustratingly low, but this is where the high volatility setting kicks in and can, on other occasions, deliver the big wins.
All in all, Iron Bank is a very entertaining online slot with the potential to win big.
