Royalty of Olympus Xmas — review

A Santa hat on Zeus. That's the short description of Royalty of Olympus Xmas, where Barbara Bang has laid snow, fir and gold over the divine shelf that every provider now has. Seasonal editions are a cheap way to squeeze an extra release out of the same foundation, and that's worth keeping in mind when assessing what is actually new here.

Royalty of Olympus Xmas under the microscope

The spec sheet says 96 % RTP and a maximum win of 15.000 times the stake. Volatility is not stated, and that's a detail I would have liked to have, precisely because it matters more to the bankroll than any other single figure. The release date is 23. december 2025 — two days before Christmas, which says everything about how narrow the window for that kind of title is.

01A seasonal skin — but what's underneath?

The theme list mixes Christmas and New Year, Christmas tree, snow and gold with the classic Olympus baggage: cup, helmet, harp, gems and Zeus himself. It's a mash-up hardly meant as a mythological consequence, more an excuse to reuse a familiar grid in December.

That doesn't automatically make the game bad. A seasonal skin on functioning math is still functioning math. But it means you should judge the title by the feature list rather than the packaging, because the packaging is the part that's been changed.

02Feature list: cascades and wins without paylines

Avalanche and Cascading both appear on the list along with Pay Anywhere and Scatter Pays. The combination is familiar: symbols pay according to how many are on the screen, not by lines, and winning symbols disappear so new ones can fall down. One good starting position can therefore become a chain of wins on the same stake.

Multiplier, Random multiplier and Free Spins Multiplier are all present. That points to a free spins round where the multiplier is built up rather than reset, and it’s likely the route by which the 15.000x ceiling can be reached in theory. Additional Free Spins allow the round to be extended from within.

There's nothing on the list I would call innovative. It's a competent collection of standard parts, assembled in the way the market demands.

03The missing number

The volatility is listed as not disclosed. That's unfortunate, because RTP alone doesn't say anything about how the 96 % is delivered. The same percentage can come as many small wins or as a few very large ones, and the two experiences have nothing to do with each other for a player on a fixed budget.

You can guess from the mechanics — cascades plus accumulating multipliers plus a cap of 15.000x usually point towards the high end — but guessing is guessing, and I note it as a missing piece of information rather than filling the gap. Check the game's own info screen at the operator if you want an answer.

The 96 % in itself is exactly the genre standard. Neither better nor worse than the rest of the shelf.

04Timing, budget and a few warnings

A Christmas release coincides with the time of year when both free time and impulse purchases peak. That's worth noting when the game also has both Buy Feature and Bonus Bet on the list — two buttons that raise the effective stake without improving the mathematical edge.

Set a limit in advance rather than during play. ROFUS and stopspillet.dk are the Danish tools for that, and they work best before the December mood sets in. The age limit is 18.

From the demo round

Screenshots from Royalty of Olympus Xmas

I played Xmas Royalty of Olympus in the demo with a stake of DEMO 1,00 and a starting balance of DEMO 999,90. The base game runs as a tumble grid with six reels and five rows, and the wins came in small portions: DROPS WIN 0,20, then 1,00 and 0,90, with a total round of DEMO 1,40 as the best in the base game.

The Buy Bonus button at the top right opens a single window with only one option: FREE SPINS til Buy 100,00 DEMO ved en indsats på 1,00 – altså 100 gange indsatsen. Købet gav 15 free spins.

In the free spins round the multiplier sits to the left of the logo and remains hidden between spins. It started at x2, was at x9 when there were 3 free spins left, and ended at x12 on the last spin. Along the way an x3 symbol landed on the reel. Total win grew from DEMO 8,50 to DEMO 25,00, and the balance ended at DEMO 901,70.

The rule set

Game rules

Base game

The game runs on the provider's standard setup. The published return to player is 96 %, and the volatility is listed as —.

Round extension

If more scatters land during the free spins round, it is extended with extra spins. That's the mechanic that makes long rounds possible.

Avalanche mechanic

The reels clear winning symbols and let new ones fall down from above. One paid combination can thus turn into a longer sequence.

Bonus bet

With an increased stake, the frequency of bonus triggers rises. That does not change the game's theoretical return in your favour.

Bonus buy

The bonus round can be bought directly for a fixed amount of the stake instead of waiting for scatters. The price is shown in the game's buy window — and some operators turn the feature off.

Cascades

Symbols in a win are removed, and new ones fall down instead. The chain continues as long as new wins are formed by the fallen symbols.

Free spins

The scatter symbols trigger a round of free spins. The number of spins and the required number of scatters are shown in the game's info panel and can vary slightly between operators.

Final word from the summit

The verdict

Plus
  • Cascades and Pay Anywhere are a well-tested and entertaining combination
  • Cap of 15.000x at the high end of the shelf
  • Multiplier in the free spins gives the round a real purpose
Cons
  • Volatility is not stated — the single most important piece of information is missing
  • RTP at 96 % is merely standard, nothing more
  • The Christmas theme is a skin on top of a fully recognizable structure
  • Buy Feature og Bonus Bet entice higher stakes in the most expensive month
6,5

Royalty of Olympus Xmas is a seasonal variation, not a new development. The feature list is solid and well-proven, the ceiling is high, but RTP is at standard level, and the missing volatility figure makes it difficult to give concrete advice on bet size. I land on 6,5: there's nothing outright wrong, but there's also nothing to justify choosing this one over a dozen nearly identical Olympus titles with better-documented figures.

Frequently asked questions

What is the RTP in Royalty of Olympus Xmas?

The spec sheet states 96 %. That is the genre's standard value and a theoretical average over very long runs of spins, not something that tells you about a single evening.

How volatile is the game?

The volatility is not disclosed in the data we work from, and we do not guess. The feature composition with cascades and built-up multipliers normally points toward the high end, but it should be confirmed on the game's own info screen at the operator.

What is the maximum win?

15.000 times the stake. It's a theoretical cap that requires an extremely unlikely chain of cascades and multipliers.

Is it just a Christmas skin on an existing game?

The theme mixes Christmas with the usual Olympus inventory, and the feature list consists of familiar standard parts. The provider is Barbara Bang, and the release date is 23. december 2025.
