High roller

A high roller, also referred to as a whale or cheetah, is a gambler who consistently wagers large amounts of money. High rollers often receive lavish "comps" from casinos to entice them onto the gambling floors, such as free private jet transfers, limousine use and use of the casinos' best suites. Casinos may also extend credit to a player to continue betting, and offer rebates on betting turnover or losses; and contracts of employees may also contain incentive arrangements to bring in high rollers.
