This JiLi333 RTP vs volatility comparison starts from one contrast: Pragmatic Play’s Sweet Bonanza publishes 96.48% RTP at medium-to-high volatility, while Gates of Olympus publishes 96.50% RTP at high volatility. Two figures a tenth of a point apart carry different volatility labels, which is exactly why the two numbers need reading side by side rather than as one blended score. JiLi333 already covers what RTP measures and what volatility measures elsewhere, so this page compares them instead, using six titles where the two figures pull apart.

The question worth answering before choosing a stake is which of the two numbers actually describes a single evening at the reels. This comparison sits under the online slots Philippines breakdown, and six named examples below answer the question directly.

Same RTP, Different Sessions: Gates of Olympus and Gates of Olympus 1000

Both games publish 96.50% RTP. Gates of Olympus carries a high volatility label and a 5,000x maximum win; its sequel, Gates of Olympus 1000, carries very high volatility and a 15,000x maximum win. Identical long-run returns, on paper, describe two sessions that feel nothing alike, since the sequel’s multiplier meter locks in gains across a whole free-spins round instead of resetting per tumble. RTP alone would suggest these two games are interchangeable; volatility says otherwise.

Same “High” Volatility Label, Three Different RTPs

The original Gates of Olympus sits at 96.50%, The Dog House at 96.51%, and Big Bass Splash at 96.71% — all three labelled high volatility. A 0.21-point RTP spread across three games is smaller than the spread this catalogue shows between two titles sharing an identical RTP. Volatility groups these three together for session feel; RTP barely separates them at all.

Medium Volatility Across PG Soft’s Catalogue

Fortune Tiger publishes 96.81%, Mahjong Ways publishes 96.92%, and Treasures of Aztec publishes 96.71% — all three labelled medium. Fortune Tiger resolves its biggest payouts on a compact 3x3 grid through a full-screen condition, while Mahjong Ways spreads its return across a never-resetting free-spins multiplier on a larger grid. Two games with the same volatility label and close RTP figures can still deliver a session through completely different mechanics.

RTP vs Volatility: What Each One Actually Measures

RTP and volatility both come from a game’s paytable and reel maths, but they answer separate questions, shown clearly by pairing each figure with what it does and does not tell a player:

FigureWhat it measuresExample on this site
RTPLong-run share of turnover returned, across millions of spinsSweet Bonanza: 96.48%
VolatilityThe shape those returns take — frequent and small, or rare and largeSweet Bonanza: medium to high

Sweet Bonanza’s own RTP figure says nothing about its volatility label, and its volatility label says nothing back about the 96.48% figure — each row in the table above is measuring something the other row cannot. Reading only one of the two is reading half the paytable.

Slot RTP vs Variance: Reading the Two Together

Variance is another name for volatility, and reading it beside RTP is what turns two numbers into a usable picture. A 96%-plus RTP paired with high volatility, as on five of the six titles compared here, means the long-run return arrives through occasional large payouts rather than steady small ones. The same RTP paired with medium volatility, as on the PG Soft titles above, spreads that same long-run return more evenly across a session. Checking both figures before setting a stake is what separates a deliberate choice from a guess.

Sorted by RTP, the table shows almost no spread — 0.42 points, top to bottom. Sorted by volatility, the same six titles split into two groups whose sessions feel entirely different.

Why Volatility Predicts a Session and RTP Does Not

RTP describes an outcome that needs millions of spins to show itself, and no single evening reaches that sample size. Volatility describes the shape of results over a much shorter run — how often something pays, and how large a single payout can be — which is exactly the timeframe one session actually covers. Mahjong Ways publishes a 25,000x maximum win at medium volatility, while The Dog House publishes a much lower 6,750x maximum at high volatility — the higher volatility label, not the smaller ceiling, is what actually warns a player about longer dry spells between payouts. RTP never carries that warning; only the volatility label does.

Which Number to Check First

Problem: Choosing Sweet Bonanza over Gates of Olympus by RTP alone — 96.48% against 96.50% — looks like a coin flip, when their volatility labels of medium-to-high and high describe two different sessions entirely.

Fix: Read the volatility label first, then use RTP only to compare titles that already share a similar volatility label. Applied here: Gates of Olympus (high) and Big Bass Splash (high) are the pair actually worth comparing on RTP, not Gates of Olympus and Sweet Bonanza. Once volatility narrows the field, how a maximum win figure fits into that picture and the bet-size method covered elsewhere on this site turn the comparison into an actual stake.

FAQ

Does a shared RTP mean two slots play the same?

No. Gates of Olympus and Gates of Olympus 1000 both publish 96.50% RTP, yet one is high volatility and the other very high, producing completely different sessions.

What does volatility predict that RTP does not?

Volatility describes how often a game pays and how large a single payout can be — the shape of a session — while RTP only describes an average that needs millions of spins to appear.

Is variance the same thing as volatility?

Yes. Variance is another name for the same figure, describing how a game's results spread out around its published RTP.

Which number should be checked first before setting a stake?

Volatility, since it describes what a single session is likely to feel like; RTP is more useful for comparing titles that already share a similar volatility label.
