Developer Aerosoft's Grand Casino Tycoon brings players into the world of gambling and challenges them to build and run a successful casino that caters to a variety of gamblers. To become profitable, casino managers must develop a strategy to manipulate their guests' behaviors and encourage them to continue parting with their hard-earned money. Casinos must fulfill a list of requirements to attract customers and then must continue to satisfy customer demands to improve the popularity of the establishment.

The most unique feature of Grand Casino Tycoon is the sorting system. Gamblers are profiled into several different types. These include humorous stereotypes like the Posh Gambler, the Compulsive Gambler, and the Slot Zombie. Each gambler type follows a specific routine upon entering the casino. Each gambler type also has a list of requirements that must be met before they will be attracted to the casino and a list of likes and dislikes. If gamblers encounter something they dislike, it can bring the popularity score with that gambler type down. These requirements, routines, and likes and dislikes will help inform the way casino owners set up their casino.
