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.

How to play
Get your tickets ready and hold tight, for Money Train 4 comes packed with features.
Let’s start with the betting range: The minimum bet is 10p, and the max bet is £2 (aged 18-24) and £5 (aged 25+) per spin.
Due to the enormous max win (and risk exposure to the casino), some top-rated UK online casinos have chosen to lower the maximum bet.
Winning combinations are formed when at least 10 identical symbols appear (or at least 8 of the highest-paying symbols).
Landing a full screen of the same symbols pays between 100x and 1,000 the bet.
Features and free spins bonus explained
Money Train 4’s base game is not what this slot is about. It shines in the Hold and Win bonus round!
Respins Feature
The Respins Feature may trigger at the end of any spin. Whichever symbol is the most present on the grid becomes sticky, and a free respin is awarded. Only blanks, multipliers, or more of the sticky symbols can appear. Landing multipliers or symbols keeps the feature going. New symbols become sticky, but multipliers do not. Multipliers are added together and multiply the final win. The Respins Feature ends when no new symbols land.
Money Cart Bonus Round
The Money Cart Bonus is “where the magic happens” and is triggered when 3 or more scatter symbols land in the base game.
This bonus round is initially played on a 6 x 4 grid, which can fully expand to a 6 x 8 grid.
Triggering symbols reveal a multiplier value, and three respins are awarded, with all symbols held. Should a new symbol land, the three respins are reset.
Filling a whole row with symbols opens an extra row, giving you better chances of landing new symbols.
Now this is all pretty standard Hold and Win stuff, but what sets Money Train slots apart are all the extra features you can win.
And boy, does Money Train 4 have plenty of them!
Bonus Symbols – these reveal a multiplier value of 1 – 10 times the bet.
Collector – this powerful feature collects all visible multipliers and adds them to its value.
Persistent Collector – same as above, but activated on every spin.
Adjacent Collector – collects all adjacent positions’ values and adds them to his value.
Persistent Adjacent Collector – same as above, but activated on every spin.
Payer – adds a revealed value to all other visible symbols.
Persistent Payer – same as above, but is activated on every spin. The Persistent Payer does not pay itself.
Adjacent Payer – reveals a value and adds this value to all adjacent symbols.
Persistent Adjacent Payer – same as above, but is activated on every spin.
Sniper – the Sniper doubles the values of 3 to 8 other Bonus symbols and can act on the same symbol more than once.
Persistent Sniper – same as above and is activated on every spin. Probably the most potent feature of Money Train 4, if the correct values are doubled.
Collector Payer – a two-for-one feature, the Collector Payer selects 3 to 5 symbols, adds their values to its own, and then adds the updated value to each of its chosen symbols.
Persistent Collector Payer – same as above, but is activated on every spin.
Arms Dealer – a superb and compelling feature that converts 1 to 4 regular symbols into a feature symbol. After the conversion, the feature is activated.
Persistent Arms Dealer – same as above and is activated on every spin.
Necromancer – probably the coolest of all features: it breathes new life into 2 to 7 non-persistent feature symbols.
Persistent Necromancer – same as above and is activated every spin.
Persistent Shapeshifter – Turns into the Collector, Payer, Sniper, Collector Payer, Arms Dealer, or Unlocker after each spin.
Unlocker – unlocks a locked row, creating a bigger grid.
Reset Plus – increases the reset value of the spin count by +1.
Upgrader – Upgrades up to 3 feature symbols to Persistent versions.

CasinoWizard’s verdict: 10 out of 10
Money Train 4 is the final destination for the Money Train franchise, and it has been, to put it mildly, a wild ride.
From the first millisecond when the gorgeous intro starts, you just know something special is coming up.
Even bigger, bolder, atmospheric, and flashier than Money Train 3, Money Train 4 manages to captivate, enthrall, excite, and punish slot players like no other slot. Boasting a max win of no less than 150,000x the bet and 20 (!) special bonus features, it will keep you wanting more and more with every spin.
It’s a beast of an online slot and a worthy closing chapter of one of the most successful slot franchises of all time.
A must-play.
