Its greatest profits came from an amusement arcade operating in a small room next door to the Sans Souci that was not advertised since there was no official license for its exploitation.

Sans Souci, as well as Tropicana and Montmartre, has a gambling room with roulette, craps and chemin de fer, etc.

The management of Norman “Roughneck” Rothman, a mafia associate who was married to the Cuban Olga Chaviano, a star at the Sans Souci between 1953 and 1955, preceded the management of William G. Buschoff, known as Lefty Clark, from Miami Beach, one of the men of Santo Trafficante Jr. A report by the Department of the Treasury written in Havana considered Buschoff a suspect of drug trafficking; Santo Trafficante was also a suspect.

In reality, it is almost impossible for a player to win enough points for the prize, but this is concealed by the game's unintuitive use of probability, and deceptive behavior on the part of the operator.

Jay Mallin records the game being played with eight dice instead of marbles and holes, in Cuban nightclubs and casinos in the 1950s.
