Pachinko is a game resembling pinball, which originated in Japan in the early 20th century. It is played on a device similar to a vertical pinball machine, but instead of controlling the flippers, players shoot small steel balls up the board and hope they land in a pocket. The aim of the game is to collect as many points as possible by having the balls fall into certain pockets. Pachinko is still popular in Japan today, and has become a popular form of gambling in recent years.
