Pacman was the idea of Japanese game designer Toru Iwatani, and was inspired by a pizza with a slice missing.
It was orginally named 'Puck-Man' by Japanese games company Namco
but they realised that graffiti might not do their advertising any
good!
The game was based on a classic Japanese tale about a creature
that protected children from scary monsters by eating them. In the
game, four ghosts chase Pacman around a maze and he eats little
dots. If the Pacman eats a power pellet it allows the hunter to
become the hunted as the ghosts turn blue and scatter to all parts
of the maze.
There was of course a plethora of merchandise including T-shirts,
lunch boxes and bags.
