All online slots, most definitely, are not created equal. Aside from gameplay options like graphics and bonus features that make one slot or another attractive to different players, there are also more basic characteristics that make certain slots more suitable for players with specific gambling styles.
Return to Player – RTP
If you’ve read anything about slots online, you’ve probably heard of the return to player rate, often referred to as a slot’s RTP. This number represents what percentage of bets made on the slot will be returned to players as winnings over the long term. You may have also noticed that most modern online video slots have an RTP rate of about 96% to 97%. So, for example, a slot with a 96% RTP rate would return about £96 to players for every £100 wagered, leaving £4 for the casino.
The key point to remember is that the RTP rate represents returns over the long term — as in hundreds of thousands, or even millions of spins. In the short term, it is possible to win or lose much more. For example, you could play 50 spins at £1 each and lose £50 rather than the £48 that a 96% RTP would dictate. Someone else could play another 50 spins and walk away £200 richer, which certainly didn’t give the house their £2 share of the £50 wagered. But, over time, as more spins are made, the total money wagered and won will get closer and closer to that 96% return to player rate.
Did you ever wonder, though, why some slots seem to stay more in line with their return rate as you play while others produce wild up and down fluctuations in your bankroll even though both have similar RTP rates? This happens because there is a second factor that determines how much and how often slot machines will pay out. It’s called volatility. Volatility is used to describe how a slot machine behaves over the short term. Volatility is often the factor that makes a gambler feel comfortable playing one slot but uneasy playing another. It can also be the factor that determines whether a player thinks of a particular slot as exciting or boring.
Different levels of volatility will make slots more or less suitable for different gambling styles. Slots with low volatility pay out more often but award smaller prizes. They will produce a minimal variance in your bankroll. Slots with high volatility will award larger payouts but it will take lots of losing spins to hit those high-paying winners. They will produce plenty of ups and downs over the short-term as you play.

Conservative Gamblers – Low Volatility
In general, more conservative gamblers, or those with smaller bankrolls, will prefer slots with lower volatility. There is a smaller chance of going broke quickly and play time can be extended to the maximum. The more or less constant stream of small payouts keeps anxiety at bay. The tradeoff, however, is that the game might not produce much excitement and even the maximum payout is going to be small compared to many other slots.
High Rollers – High Volatility
High volatility slots will be more attractive to those with the opposite gambling style. Players with larger bankrolls or those looking for more excitement, especially casino high-rollers, often prefer slots with high volatility. The possibility of higher payouts and more excitement, however, comes with a higher risk of going broke before those big wins materialize.
Then, of course, there are plenty of slots that fall somewhere in the middle of the spectrum. You might see slots labelled as medium volatility, or medium-low or medium-high. The thing about volatility, though, is that unlike RTP rates, the volatility level of most slots is not published. So, it’s up to the player to make a few spins and determine if any particular video slot is a fit for his or her style of gambling and comfort level.
No matter which type of slots you prefer, we happen to have some brilliant suggestions that will surely add a few more titles to your list of favourites. Even though many online video slot machine designers don’t publish the volatility of their games, we’ve been through hundreds of them and compiled lists of some of the best high and low volatility slots.
Slot Volatility & RTP FAQ
Volatility is a statistical measure that reflects how often you can expect a slot game to pay out over a specific period of time and how big the prize will be.
a) High volatility slots: pay fewer times but offer higher return.
b) Low volatility slots: pay more often, lower return.
Software providers sometimes display this information on their site, accompanied with RTP and variance.
Slot variance reflects the dispersion of the returns of a specific slot machine on the long run and how much it deviates from the statistical average.
They basically mean the same, but the difference consist in the analyzed time period. While volatility refers to the short term, variance analyzes the long term and the dispersion from an average. Slot volatility is a good measure of how much risk is involved in the short term.
There are not good or bad slots. They may be suitable – or not – to your game style. For example, low volatility slots are great for players who have a tight budget but may be boring for high rollers. If you are a risk taker (and have a budget to back you up) you will definitely enjoy playing high volatility slots much more.
Strategies will depend on your game style and budget, but if you are going for high volatility slots, I would suggest to:
1. Set a budget and stick to it.
2. High RTP and high variance is what you should look for.
3. Do your research and bet wisely.
4. Expect few to no payouts.
5. Take breaks and be conscious about budget management.
