In grid capture games, also called line coloring games, the maze consists of lines, and the goal is to capture rectangular areas by traversing their perimeters. The gameplay is not fundamentally different from
Pac-Man (players still have to navigate the entire maze to complete a level) but enough games have used the grid motif that it is a distinct style. One unique element is that it is possible to capture multiple rectangles simultaneously, usually for extra points.
Amidar established the model for this subgenre. ==References==
