PK111 High RTP Slots: Ranked by What Each Studio Discloses

Not every game on this list of high RTP slots can actually be ranked by RTP, and that is the whole point of building it this way rather than pretending otherwise. Among this site’s sixteen title slice, PG Soft publishes a figure for every one of its five games, Pragmatic Play publishes a single figure for its one title here, and JILI publishes nothing at all across its ten. The PK111 slot volatility pillar covers why that split exists; this list shows exactly where each title lands.

High RTP slots: what each provider actually publishes

Title	Provider	Published RTP	Volatility	Max win
Mahjong Ways	PG Soft	96.92%	medium	25,000x
Fortune Tiger	PG Soft	96.81%	medium	2,500x
Fortune Ox	PG Soft	96.75%	medium	2,000x
Wild Bandito	PG Soft	96.73%	high	25,000x
Treasures of Aztec	PG Soft	96.71%	medium	not quoted
Gates of Olympus	Pragmatic Play	96.50%	high	5,000x
Super Ace	JILI	not published	low to medium	10,000x
Fortune Gems	JILI	not published	low to medium	375x

Five PG Soft titles carry a published figure, one Pragmatic Play title carries a single published figure documented elsewhere as the top of a wider set, and two JILI titles carry none at all. Each is covered below in that order.

1. Mahjong Ways

At 96.92%, this is the highest confirmed RTP figure anywhere in this site’s slice. The number comes from PG Soft’s own published game data, not from the visible game page, which shows a blank dash where the figure would sit. The 5x4 grid runs as 1,024 ways rather than fixed lines, and its free-spins multiplier climbs with every cascade in a round without resetting. The full RTP spec for this title covers the grid and features in more depth.

2. Fortune Tiger

A compact 3x3 grid with five paylines carries a published 96.81% RTP. The small grid is the design, not a limitation: it makes the game’s full-screen multiplier conditions, 10x for an all-matching screen and 500x for an all-wild one, actually reachable in a way a larger grid could not replicate. PG Soft’s RTP data sheet for this title has the rest of the spec.

3. Fortune Ox

PG Soft’s data lists 96.75% for this title’s irregular 3-4-3 grid, four symbols on the middle reel against three on each outer reel, evaluated across ten paylines. The feature synchronises all reels into a respin that continues until a win lands, which makes the respin a certainty rather than a retry. How this slot’s synced-reel feature actually works is covered on its own page.

4. Wild Bandito

96.73% is published for a title that carries a high volatility label, unlike most of PG Soft’s other games in this slice, which sit at medium. Its free-spins multiplier never resets across the round, which is the specific mechanic behind that higher label. This slot’s full multiplier mechanic is written up separately.

5. Treasures of Aztec

96.71% comes from PG Soft’s published data, but this title’s maximum win is not quoted here at all. Independent simulation puts a practical ceiling near 9,071x against a 100,000x maximum exposure figure in PG Soft’s own data field, an order of magnitude apart, and favouring one number over the other would misrepresent it. Why this slot’s maximum win figure is disputed is explained on this title’s own page.

6. Gates of Olympus

Pragmatic publishes a single RTP of 96.50% for this title. Independent records document three operator-selectable configurations for it, 96.50%, 95.51% and 94.50%, and Pragmatic’s own page discloses only the highest. A published Pragmatic figure is the best configuration on offer, not necessarily the one behind any specific spin, which the RTP meaning page on this site covers in full. This slot’s tumbling-reel mechanic is documented on its own page.

7. Super Ace: no published figure at all

Super Ace carries the largest search volume of any title in this entire slice and no published RTP whatsoever. JILI’s own fourteen official game pages, all examined directly, carry no RTP field. A 10,000x maximum win is disclosed; the return figure behind it is not, and no aggregator number stands in for it here. What this JILI slot’s golden-card feature does is covered on its own page.

8. Fortune Gems: the same absence

A 375x maximum win is published, the smallest ceiling among the four “Ace”-adjacent and Gems titles in JILI’s catalogue, but the RTP field that would normally sit beside it is simply not there, on this title or any other JILI carries. This JILI slot’s multiplier mechanic behind that 375x figure is covered separately.

How to choose

Start with what is actually checkable. On a PG Soft or Pragmatic Play title, that means reading the published figure and, on Pragmatic specifically, remembering it may be the top of a wider set rather than the whole picture. On a JILI title, RTP is not the checkable figure at all; volatility and the published maximum win are, and how often hit frequency slots actually pay fills in the third piece regardless of which provider made it.

None of these figures changes with how a session is staked. The number is fixed by the game’s own mathematics before a single spin is placed.
