Dolly (Roulette term) – The doll-shaped marker placed on the table in the square of the winning number. It helps players identify the winning number and remains in place until all winning wagers are paid. Unlike French Roulette. where the dealer simply uses a stick to point to the winning number, in American Roulette there’s a special marker made from wood or plastic that the dealer places on the table, over the winning number.
It got its name from its doll shaped outline.
