As a result of the pandemic, Holland Casino said that in 2020 it was "deepest trough ever".
Revenues were more than halved and the bottom line was a loss of 80.7 million euros.
This is evident from the annual report that the casino operator published on Tuesday.
Last year, the Holland Casino branches could only be open for 71 days without restrictions.
The casinos were closed for much of the year.
As a result, the number of visitors was more than halved, from 6.2 million in 2019 to 2.5 million last year.
With an average of 133 euros, visitors spent more than the 117 euros in the previous year.
As a result of the declining income, Holland Casino previously decided to say goodbye to about three hundred employees, about 10 percent of the workforce.
This also includes forced redundancies.
Although the pandemic is not over yet, CEO Erwin van Lambaart is positive about the future.
"Despite the constantly changing circumstances and major challenges caused by this crisis year, I firmly believe that we will get through it well."
Van Lambaart indicates that he expects the casinos to reopen sometime in the course of this quarter, albeit with restrictions. When the restrictions have disappeared completely, he expects a peak in the number of visitors. "The interest in casino visits last summer also showed this." He does, however, take into account an economic recession, which will affect casinos.
