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 that are guarded by wooden pegs; penalties are incurred if the pegs are knocked over. It probably developed from the table made with raised sides for trou madame, which was also played with ivory balls[1] and continued to be popular into the later 19th century, after which it developed into bar billiards, with influences from the French/Belgian game billard russe (with supposed Russian origins). A bagatelle variant using fixed metal pins, billard japonais, eventually led to the development of pachinko and pinball.
