We know that land-based casinos use a variety of tactics to keep customers inside and encourage them to play more. Most of these tactics are based on smart design tricks. For example, casinos do not have windows, and there are no clocks on their walls. This is because of the feeling of time: when you step in a casino, the time stands still. But simple design tricks aren’t the only tool casinos use. They also get help from psychology and visual stimuli to increase your gaming time and even raise your bet amounts. This also applies to online casinos. In fact, we can even say that they make more use of psychological tactics because they do not have a physical presence: They have to be content with visual stimuli. The use of colors, in this regard, is one of the most common tactics used by online casinos.
