Roulette is a game of chance where players wager on what number will come up. They place their chips on a betting mat, the precise location of which indicates the bet type.
A roulette cylinder has thirty-six compartments painted alternately red and black. A green compartment carries the numeral 0, and a second green one carries the number 00.
Origin
The earliest known game of roullete was invented in the 17th century by Blaise Pascal as part of his search for a perpetual motion machine. He combined a wheel with the earlier games of hoca and portique to create a new game that was named after a French city. Other fanciful stories of the origin of roulette include claims that it was invented by a monk or even by the Chinese.
There is also evidence that soldiers of the Roman and Greek armies played a game that was similar to modern roulette. They would spin shields that had symbols on them and bet on which symbol the shield would stop in front of after spinning. However, it’s impossible to determine whether this is the actual ancestor of roulette.
