Casinos and mirrors

We all know that land-based casinos have no windows or clocks. The reasons for this are clear. But there is another element of the interior design that marketers and neuroarchitects use to subtly influence players’ behaviour. These are mirrors.
So, why do traditional casinos generally avoid placing mirrors at eye level? Casinos create an atmosphere of wealth, luxury and success. And players are meant to feel as though they belong in that world. But the moment someone who has been playing for eight or more hours straight accidentally catches sight of their real reflection — the illusion of wealth, luxury and success can vanish into thin air. The player is brought back to reality, feels disappointed and walks away.
At the same time, there are exceptions. Mirrors are actively used in concealed areas. Behind the rows of slot machines. This creates the illusion of endless space and masks a dead end, making the casino floor seem boundless.
On the ceiling. In some establishments, the ceiling is often mirrored or features a golden mosaic. This diffuses the light, visually raises the ceiling and creates a sense of glamour and grandeur. People relax, feel safe and take greater risks whilst playing.
However, it is possible that one-way mirrors may also be used to conceal security surveillance.

Mirrors are interesting because they can make a casino feel bigger and brighter than it really is. I wonder how much that affects players’ sense of time.

Actually, it seems to me that you quite often come across mirrors in gambling halls—especially where the slots are. As for areas with card tables, though, I’m not sure, I haven’t really paid attention.
