Amidar

Amidar is a maze video game developed by Konami and released in arcades in 1982. It was distributed in North America by Stern. Parker Brothers published an Atari 2600 version in late 1982, and Casio released a port for the PV-1000 in 1983. Amidar was the first in the grid capture sub-genre of maze games and was highly cloned in arcades and for home systems.

The player moves around a fixed rectilinear lattice, changing the color of the lines, while avoiding enemies. Coloring all the lines around a rectangle fills it in. When all the rectangles have been filled, the player moves to the next level. There are two types of levels which alternate, with the player controlling a paint roller in one and a gorilla in the other.

The game and its name have their roots in the Japanese lot drawing game Amidakuji. The bonus level in Amidar is a nearly exact replication of an Amidakuji game and the way the enemies move conform to the Amidakuji rules; this is referred to in the attract mode as "Amidar movement".
