Casino scent marketing
In a casino, every minute your guest stays counts. Scent directly influences this dwell time – and this was measured at slot machines in Las Vegas.

The study that began in Las Vegas
Scent marketing in casinos is not a new idea, but one of the best-documented applications of all. Dr Alan Hirsch of the Smell & Taste Treatment and Research Foundation studied two identical rows of slot machines in a Las Vegas casino, one of which was subtly scented.
In the scented zone, revenue during the study period was significantly higher than in the control row next to it. Even more important was how this effect arose: not because players bet more per game, but because they stayed seated longer.
That makes the study relevant for every gaming venue. In an environment where guests decide for themselves when to get up, dwell time is the metric everything revolves around.
- ✓︎The mechanism: scent extends dwell time, not the stake per game
- ✓︎The prerequisite: dose low, because guests stay for hours
- ✓︎The basis: first break down smoke and sweat odours, then the atmospheric scent
- ✓︎The system: via the ventilation, with separately adjustable zones
Two identical rows
The same machines, the same location, the same visitor flow. Only the scent differed – so the effect can be attributed to this one factor.
Higher revenue per zone
The scented row recorded significantly higher revenue than the control row next to it during the study period.
Subtle, not conspicuous
The scent was dosed low and was not consciously named by most guests. It was precisely this subtlety that made it effective.
Why it works
Scent reaches the limbic system almost immediately – the part of the brain that controls well-being and behaviour, before the guest even thinks about it.
Your most important metric is time at the table
Scent influences this time in two ways. A pleasant scent lowers the threshold to stay – players simply have no reason to get up. Neutralisation also removes the smoke, sweat and musty odours that subconsciously make guests leave. In practice, the latter is often the biggest gain.
The threshold to stay
An environment that smells pleasant gives no reason to get up. Guests stay longer without knowing why.
The reason to leave
Smoke odour, sweat and stale air are the silent reasons why guests get up earlier. Neutralisation removes them.
The memory afterwards
Scent links to memory. A well-kept environment already feels familiar on the next visit – and that increases return visits.
Your staff too
Croupiers and hosts stand here for an entire shift. Clean air is not a luxury for them but a working condition.
The smoke smell that comes back after cleaning
VernovaPure® is a patented technology. Instead of masking odours, its active molecules bind to the odour-causing substances and break them down at the source. This clears the air and forms the basis for a lasting scent experience.

Why sweet doesn’t work here
A vanilla or fruit scent works brilliantly in a bakery where the customer stays for ten minutes. On a casino floor they stay for four hours – and then sweet turns oppressive.
That is why we choose woody and mineral compositions here: they don’t become cloying and remain pleasant even after hours. Luxury lies in restraint, not in emphasis.
Does your casino also have a restaurant or an event hall? For dining, follow the approach in ambient scenting for restaurants; for halls and foyers, that of event venues.
One large floor,
several zones
A casino floor cannot be served with individual units. The modular scent system XL is connected to your central ventilation unit and covers up to around 1,000 m²; the scent follows the existing airflow. For smoking rooms and washrooms, a separate modular scent system works with its own setting.
Via the Zaluti Smart Control App you set one of 99 intensity levels per zone, plus a weekly schedule based on your opening hours. So the floor runs higher on a busy Saturday evening and lower on a quiet afternoon.
Questions about scent in casinos
Does scent marketing work in a casino?
How does scent extend dwell time in a casino?
Dwell time is the time a guest spends in a zone, and in a casino it is the most important metric: every extra minute at the table or machine counts directly. Scent influences this time in two ways. A pleasant scent lowers the threshold to stay, and neutralisation removes the smoke, sweat and stale air that subconsciously make guests leave.
Which scent suits a casino?
Choose a scent that exudes luxury without becoming cloying, because guests stay for hours. Warm, woody compositions such as Cashmere Wood or Exquisite Elixir work well at the entrance and at the gaming tables. On the slot floor and in smoking rooms, use a neutralising scent such as Fresh Water or Neutral. Avoid sweet and perfume-heavy scents: with long dwell times they quickly feel oppressive.
How do I get the smoke smell out of my casino?
By neutralising instead of masking. Tobacco smoke settles in upholstery, carpets and walls and returns after cleaning because the molecules are still there. VernovaPure® binds to these odour-causing substances and breaks them down at the source, with a measured reduction of up to 93% for tobacco smoke.
Does scent disturb players' concentration?
Not if you dose low. In a casino, the aim is a scent that stays in the background: clearly but gently noticeable on entering, then barely consciously perceived. You set the intensity per zone and keep it fairly low, precisely because guests stay for a long time and too strong a scent then turns into irritation.
How do you scent a large casino floor?
Via a connection to the ventilation system rather than with individual units. The modular scent system XL is connected to the central ventilation unit and covers up to around 1,000 m², with the scent following the existing airflow. You set a separate intensity per zone, so that entrance, gaming tables and washrooms remain separately controlled.
