Casino is a movie about money, power and the ability to control others. It is full of greed and corruption, but also human tragedy. It is also a film about the strength of family bonds, especially between sisters.

Casinos depend on people spending their money to stay in their buildings and gambling away their hard-earned cash. They have a number of tactics up their sleeve to keep these money-losing customers on the premises as long as possible.

One of the most common tricks is to strategically place toilets, restaurants and cash machines deep within the casino so that players must pass many slot machines and tables on their journeys to these facilities. This gives players the burning temptation to make one more bet, even if they were only planning on leaving after a quick visit to the bathroom or getting a snack.

Another trick is to remove any cues that let players know how much time has passed since they entered the building. Casinos often do this by removing clocks and windows, so players lose track of how long they have been gambling, encouraging them to continue playing for longer periods.

Casinos also reward their loyal customers with perks like free meals, drinks and hotel rooms. These rewards, known as comps, encourage players to gamble more in order to earn the perks and maintain their loyalty status. This strategy is considered highly effective, as it makes players feel valued and increases their motivation to continue gambling.
