Ultra Hot deluxe in numbers and blank fields
Novomatic brought Ultra Hot deluxe from land-based arcades to the browser through its online division, Greentube. It is one of the studio's simplest slots, yet its public fact sheet leaves a surprising amount out.

Three of the nine rows read ‘not published’. That is not a gap in our research – it is exactly how the Austrian studio's public game profile looks.
Nine positions on screen, five routes to a win
The grid has three reels and three rows, nine positions in total. Five fixed paylines run across them; the in-game paytable shows their exact paths.
There is only one way to win: three matching symbols in a row on an active line. Nothing substitutes for a missing symbol, nothing triggers an extra round, nothing is collected for later.
Every spin settles straight away. No cascades, no bonus animations – the result is there within a second, the next spin one tap away.
The only booster: a full grid of one symbol
If the same symbol fills all nine positions, the win is doubled. That is the only exception to the three-in-a-row rule. No counter, nothing to unlock – the screen either shows one motif or it does not.
Bigger results do not build through a chain of features; they arrive in one go. In the more modern Hot Lucky 7's, wins come from multipliers on wilds and from free spins. Here the only multiplier is a match across the whole grid.
So you are waiting for one picture.
Volatility 4 of 5 in a game with no features – does it add up?
It looks odd that such a bare machine gets a four on the studio's five-point scale. The logic is simple: without wilds and free spins to smooth things out, only the symbol distribution on the reels and the paytable decide the outcome – and nothing breaks up longer stretches without a win.
Novomatic uses the 1–5 scale across its catalogue, so comparisons work within its portfolio. Dolphin's Pearl deluxe scores a five on the same scale. A four cannot be compared directly with games from studios that say ‘medium’ or ‘medium-high’: a different yardstick, a different definition.
Illustrative example (not Dukat.bet parameters): a 20 EUR budget at 0.20 EUR per spin covers 100 spins even if not a single win lands. With a level-four game, expect dry spells like that and pick a stake the budget can survive.
The RTP you won't find on the studio's website
Novomatic and Greentube share the return figures for their online versions only with business partners behind a login. So the public has no studio figure to compare. We do not copy values circulating online – we cannot tell which version of the game they belong to.
The only reliable place is the game itself. An operator may run a different configuration from one seen elsewhere; the info panel figure is what counts.
Before your first spin, check:
- RTP in the game rules – if the info panel lists it, it applies to that specific installation.
- Stake range – the operator sets the minimum and maximum.
- The paytable – what each symbol pays and where the lines run.
- The full-screen rule – whether this version includes it in the same form.
Why the Austrian studio keeps its numbers behind a B2B login, and what that means for comparing classics, is covered in our Novomatic profile.
Who Ultra Hot deluxe suits and who will get bored
The game suits players who want an instant result with no animations or side rounds. Anyone who knows slot machines from arcades will recognise the rhythm: press, look, carry on.
It is less of a fit for someone after Bonus Buy, growing multipliers or symbol collection. They will be happier with modern video slots – our category guide shows how the two slot categories differ.
One last note: short rounds tempt you into a fast pace, so set a time limit before you start.
Slots Bonus and a three-reel classic
For slots, Dukat.bet offers the Slots Bonus – 500% up to 3,000 EUR + 15% Cashback. Check eligible titles, deposit and wagering conditions in the official bonus terms.
The same goes for the game itself: the quickest way to see whether Ultra Hot deluxe is currently in the lobby is the Novomatic provider filter.
