PAC-MAN

You are PAC-MAN, a friendly-looking yellow circle with a little wedge missing. You travel through the maze, eating dots in your path and are pursued by four ravenous monsters. If any of them catch you, you're a goner.

There are four 'energizers', one in each corner of the maze. Hit the energizers and the monsters are rendered helpless and you can eat them, making them disappear for a few seconds.

If you eat all the dots on the board, you are rewarded with another board, in which the monsters have become smarter and stronger.
