There are things which might seem normal in casinos but they are marketing tools. They are tricks to make sure gamblers bet to their last coin.
Instead of using cash, casinos use chips because chips have different colors, and they are easier to identify than money. However, that is just one reason for using chips. The other reason is psychological, whereby people would not feel significant loss if they lose chips rather than money.
People attach a lot of value to money as compared to the chips. Therefore, casinos prefer people gambling with chips instead of physical cash, to trick people into believing that there is less risk in gambling. This is because chips are worthless, as opposed to money, which no one would want to watch disappear.
There are always complimentary gifts for gamblers at casinos. These gifts may come in the form of food or drinks, and in some casinos, they even provide free accommodation. This is a trick used by casinos to make gamblers think that they have equalized their losses if they lose.
Free food, drinks and accommodation for gamblers is also another way casinos make sure players do not leave their premises before they place a wager on their last coin. When drunk, people tend to bet more, and when their stomach is full, they get comfortable, hence stay longer in the casino.
It is not by coincidence that most casinos have bright lights, stimulating sounds and music. Those lights and sounds are part of casino trickery. Bright lights make gamblers comfortable to bet as they feel secure. This is the reason as to why casinos have very bright lights.
Stimulating sounds give gamblers motivation and make them think they will be winning within minutes. This makes them keep on playing. A good combination of bright lights and the right sound puts gamblers in the right mood to keep gambling; hence, casinos know this trick and use it to make sure players bet to their last coin.
Scent is used by many companies across the world to distinguish their products. Likewise, casinos create a unique scent so that gamblers can associate the smell with them. This idea makes marketing sense since once a person smells the scent, it reminds them of the product or the place.
People are triggered by the sense of smell and casinos have mastered the art of making players gamble more by having specific scents for their casinos. Once the person gets in the casino and recognises that particular smell, their mind tells them what to do next; gamble. And that is precisely what they do.
