The players put their stakes on the numbers they wish to back. The banker is provided with a bag from which he draws a case containing a ticket, the tickets corresponding with the numbers on the board. The banker calls out the number, and the player who has backed it receives sixty-four times his stake; the other stakes go to the banker. Casanova played it in Genoa (illegally, for it was already banned there) and the South of France in the 1760s and describes it as "a regular cheats' game". He broke the bank (fairly, he claims) and was immediately rumored to have been in collusion with the bag-holder; such collusion presumably was common.
