The first form of roulette was devised in 18th-century France. Many historians believe Blaise Pascal introduced a primitive form of roulette in the 17th century in his search for a perpetual motion machine. [2] The roulette mechanism is a hybrid of a gaming wheel invented in 1720 and the Italian game Biribi.[3] A primitive form of roulette, known as ‘EO’ (Even/Odd), was played in England in the late 18th century using a gaming wheel similar to that used in roulette. The game has been played in its present form since as early as 1796 in Paris. An early description of the roulette game in its current form is found in a French novel La Roulette, ou le Jour by Jaques Lablee, which describes a roulette wheel in the Palais Royal in Paris in 1796. The description included the house pockets: “”””There are exactly two slots reserved for the bank, whence it derives its sole mathematical advantage.”””” It then goes on to describe the layout with “”””two betting spaces containing the bank’s two numbers, zero and double zero””””. The book was published in 1801. An even earlier reference to a game of this name was published in regulations for New France (Québec) in 1758, which banned the games of “”””dice, hoca, faro, and roulette””””.(資料來源 )
