The game has been played in its current form since the early 18th century when a French mathematician named Blaise Pascal invented the roulette wheel. Players place their bets on which number they think will win by selecting single numbers or groups, rows, columns, and colours from the table grid. These numbers relate to those on the wheel, which are divided by wooden slots into which a ball will settle, denoting the winning number. It consists of a large spinning wheel and a table depicting a grid split into different numbers. Roulette is one of the most instantly recognisable casino games.
