Sleepy Grandpa is available in four different RTP versions, where the best one averages a 96.23% payout.
The lower-paying versions average 88.40%, 92.32%, or 94.28% RTP.
To show you what the effect of a higher or lower Return to Player really is, we have done some calculations.
Based on a starting balance of £100 and a stake of £1 per spin, we can determine, per RTP configuration, how many spins it will theoretically take (excluding variance) before you run out of funds.

It is beneficial to recognise that these calculations are based on theoretical losses per spin. In practice, due to the slot’s medium variance, results will differ significantly as you will have many losing spins and some winning spins. But taking the variance out of the equation, you can see enormous differences between the RTP settings.
If you are looking for a safe, reliable, and High-RTP Casino, then look no further, as we have researched and found a few of these for you where you play Sleepy Grandpa. You can find them at the top of this review.
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.

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 Sleepy Grandpa
Sleepy Grandpa is a medium to high volatility slot played on a 5-reel and 4-row game panel with 26 fixed pay lines.
Bets start from 10p per spin and go up to £2 (aged 18-24) and £5 (aged 25+) per spin.
The base game adds excitement through the Dig and Tractor features, and the Free Spins take everything to yet another level as you can grow the global multiplier there.
Features explained:
Dig feature = Once a farmer symbol and a dirt symbol appear on the reels simultaneously, it’s time to start digging. The digging procedure will lead to coins that reveal a value of 1x to 1,000x.
Tractor feature = When a golden symbol lands on the reels without a dirt symbol, the plough feature kicks in where the tractor crosses the playing field and leaves 1 – 10 dirt symbols behind.
Free Spins = 3, 4, or 5 scatters trigger 10, 12, or 15 Free Spins. Each 4 collected farmer symbols during the bonus game increases the global multiplier and adds +3 spins to your total.
Sleepy Grandpa Bonus Buy
You can buy the Free Spins if you don’t feel like waiting for enough scatters to land and want to head straight for the main action.
However, this will cost you 100x your bet size, and the option isn’t available in all markets, including the UK.
What is the maximum win on Sleepy Grandpa?
Sleepy Grandpa offers an unusually high max win potential, considering it’s a medium-high volatility slot.
You can win up to 10,000x the bet while playing the slot, and the max wins probability is not bad at all, at 1 in 10 million spins.
CasinoWizard’s verdict: 7.5 out of 10
Sleepy Grandpa is an entertaining and humorous slot that was even more fun than expected.
The laid-back theme, the fun and straightforward features, and the suitable soundtrack with modern graphics package it all in a great way.
