A volatility label such as Low, Medium, or High tells you something important about a slot, but it does not always explain what the game will actually feel like. Free play can help turn that abstract label into something easier to understand.
Knowing How to Compare Volatility Using Free Play means paying attention to more than whether you finish ahead or behind.
Useful clues include losing streak length, size of regular wins, bankroll drawdowns, bonus frequency, and how much of the total return comes from rare large payouts. The trick is testing consistently without overreading random short-term results.
Start With Volatility, Not RTP
Players often compare RTP percentages first.
RTP matters, but it does not answer the same question as volatility.
Imagine two slots with 96% theoretical RTP.
One may distribute theoretical returns through regular smaller payouts. Another may concentrate more value into infrequent bonuses or very large wins.
Over an enormous number of rounds, their theoretical returns could be similar while their short-session behaviour feels completely different.
That is volatility.
Yggdrasil’s game catalogue makes this separation visible by listing RTP and volatility independently. Its volatility filters range from Low through Low-Medium, Medium, Medium-High, High, and Super High.
So when comparing games, avoid assuming that the one with the higher RTP must also be smoother.
Use the Same Testing Conditions
Free-play comparisons become messy if every game is tested differently.
Create a basic test format.
Give each game the equivalent of 500 betting units and use a one-unit wager for every spin. Then test each title for the same number of spins.
You do not have to use exactly 500 units or any particular number of spins. Consistency is what matters.
If Game A receives 100 spins and Game B receives 1,000, comparing their biggest wins or longest dry periods tells you very little.
Also avoid changing stake sizes halfway through.
Raising the virtual bet after losses changes the balance curve and makes the comparision harder to interpret.
Keep the conditions boring and consistent. That produces much more useful observations.
Count How Often the Balance Moves Up
A winning spin is not necessarily a profitable spin.
Suppose you bet one unit and receive 0.40 units back. The interface may celebrate it as a win, but your balance still fell by 0.60 units.
For volatility comparison, therefore, consider recording both:
Any paying result and results above the original stake.
This distinction helps reveal how a game maintains player activity.
One slot might produce many sub-stake returns, keeping animations busy while the balance gradually declines.
Another might generate fewer paying events but produce more noticeable jumps when they arrive.
That difference can affect how volatile the experience feels.
Be careful not to interpret celebratory effects as mathematical evidence. UK regulations specifically address game presentation and prohibit certain designs that can mislead players about outcomes.
Record Losing Streaks
One of the most noticeable signs of volatility is the length of stretches with no meaningful payout.
During each demo session, write down your longest sequence of non-winning spins.
Suppose your results look like this:
Game A: longest dry streak of 9 spins.
Game B: longest dry streak of 27 spins.
Game C: longest dry streak of 14 spins.
Game B appears more uneven during that particular test.
However, one losing streak does not define the game’s official volatility.
Random outcomes can create unusually long or short sequences. Regulated RNG systems are required to produce unpredictable outcomes and should not adapt future probabilities simply becuase a player has recently won or lost.
Repeat the test before drawing broad conclusions.
Compare Maximum Drawdown
Maximum drawdown sounds technical, but the idea is simple.
It measures how far your demo balance falls from a previous high point before recovering.
Imagine starting with 1,000 units.
Game A reaches 1,070, falls to 900, then recovers.
Its drop from the previous peak was 170 units.
Game B reaches 1,030, crashes to 580, then eventually lands a large bonus.
Its drawdown was 450 units.
Even if both games finish with approximately 950 units, their journeys were completely different.
Large, repeated drawdowns can be a strong practical sign of a more volatile payout structure.
This makes the virtual bankroll more useful than simply asking, “Did I win the demo session?”
See Where the Biggest Wins Come From
Next, divide results into base-game wins and feature wins.
Some games generate substantial wins during ordinary reel play. Others reserve much of their prize potential for Free Spins, multipliers, expanding Wilds, jackpots, or collection features.
Suppose a 500-spin session returns 450 units.
If 350 units came from one Free Spins round, the game’s results were highly concentrated during that sample.
Compare that with another game where the same 450 units arrived through dozens of smaller payouts.
The second game produced a smoother distribution.
This does not prove its exact mathematical variance, but it tells you something useful about the playing experience.
High-volatility titles often advertise substantial maximum-win potential. Yggdrasil’s Covert Chaos, for example, is officially labelled Super High volatility and lists a maximum multiplier of 20,000x.
Meanwhile, Saber is labelled Low volatility.
Official classifications give you a useful benchmark for checking what you observe.
Do Not Use Bonus Frequency Alone
A common shortcut is to say:
“Bonuses are rare, so this must be high volatility.”
Sometimes that may appear true, but it is incomplete.
A bonus can trigger frequently and still pay modestly. Another game may have rare bonuses but strong regular-reel payouts.
You need to consider the complete distribution.
Track how often bonuses trigger, but also record their results.
A bonus worth 3x the stake and one worth 300x both count as one feature trigger, yet they affect volatility very differently.
The same applies to hit frequency.
A slot can technically produce many winning spins while most are tiny payouts.
This is why no single number should replace the broader pattern.
Compare Games in Groups, Not Isolation
Free play becomes more informative when you test games with published volatility labels.
For example, choose one officially Low or Low-Medium title, one Medium or Medium-High title, and one High or Super High title.
Then hide the labels temporarily and compare how they behave.
Yggdrasil lists Gunslinger Glory as Low-Medium volatility with a 38.46% hit frequency.
Covert Chaos is listed as Super High with a 23.92% hit frequency.
After testing them, compare your notes against the provider classifications.
You may notice the lower-volatility title generally maintains the balance more smoothly while the higher-volatility title creates deeper swings.
Or your short sample may show the opposite.
That second outcome is not proof that the provider’s rating is wrong. It simply demonstrates why short random samples can be noisy.
Understand the Limits of Free Play
This is the most important part of the exercise.
You cannot reliably calculate a slot’s true mathematical volatility from a few hundred manual spins.
Professional statistical testing uses much larger samples.
The UK Gambling Commission’s testing guidance specifically says simulation testing involves running a high number of games, with the appropriate sample depending on factors including volatility.
Free play is therefore best used to answer practical questions such as:
Does the balance tend to swing sharply?
Are ordinary payouts usually small?
Does most excitement come from bonuses?
How long can quiet stretches feel?
Those observations can help you understand a game’s risk profile.
They cannot tell you what the next spin will do.
Make Sure Demo Results Are Representative
A proper demo should not secretly become easier simply because no real money is involved.
Under UK Gambling Commission standards, play-for-free versions on the same facility must use the same rules as their corresponding real-money games and should accurately represent winning likelihood and prize distribution.
That makes legitimate demo mode valuable for learning mechanics.
Still, check the information screen.
Some developer websites may use feature demonstrations designed to show certain bonus mechanics rather than reproduce ordinary gameplay, and such demonstrations should be identified accordingly under the same guidance.
Use an actual free-play version whenever possible.
Build a Simple Volatility Scorecard
You do not need complicated statistics.
For each game, record the same five things: winning-spin frequency, longest dry run, maximum drawdown, largest payout, and percentage of session returns generated by bonuses.
Then compare the patterns.
A smoother game may show frequent modest wins, shorter drawdowns, and less dependence on one huge result.
A more volatile game may display deeper balance drops, fewer meaningful wins, and occasional spikes.
Treat the scorecard as an observational tool rather than an official volatility calculation.
Its real value is helping you notice structural differences that are easy to miss when simply spinning casually.
How to Compare Volatility Using Free Play is less about finding which slot “pays better” and more about understanding payout distribution.
Use equal test conditions, track losing sequences, drawdowns, win sizes, and bonus dependence, then compare your results with official volatility data.
Most importantly, remember that demo history cannot predict future spins – use free play to understand mechanics before risking money.
