Bagatelle (from the Château de Bagatelle) is a billiards-derived indoor table game, the object of which is to get a number of balls (set at nine in the 19th century) past wooden 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 and continued to be popular into the later nineteenth century. A bagatelle variant using fixed metal pins, billard Japonais, eventually led to the development of pinball and pachinko. Bagatelle is also laterally related to miniature golf.

Table games involving sticks and balls date back to at least the 15th century, and evolved from efforts to bring outdoor games like ground billiards, croquet, shuffleboard and bowling, inside for play during inclement weather. While some games took the wickets and mallets of croquet and ground billiards and turned them into the pockets and cues of modern billiards, some tables became smaller and had the holes placed in strategic areas in the bed of the table.
