Amidar was a video game developed for arcade by Konami in 1981. This is the 1982 home version ad, released by Parker Brothers. The gameplay is very similar to Pac-Man, alternating stages where the player is a gorilla chased by wild warriors and stages where the player is a paint roller chased by pigs. The name of the game and the structure of the stages are inspired in an oriental kind of lottery called Amidakuji.
