Bagatelle (from the Château de Bagatelle) is an indoor table game related to billiards, the object of which is to get a number of balls (set at nine in the nineteenth century) past pins (which act as obstacles) into holes. It probably developed from the table made with raised sides for trou madame, which was also played with ivory balls (Gloag 1969 illustrates a London design that was current in 1782) and continued popular into the later nineteenth century. Bagatelle is the precursor of the pinball machine.
