Neave.com is a beautiful, well designed and straightforward site, created by a very talented person (Paul Neave) , who coincidentally happens to be a gamer. He also happens to offer nine excellent retro games for our amusement (and for free). One of these games happens to be a little-known gem called Pac-Man. Another one of the obscure little titles featured is called Space Invaders. Have a look.
P.S. Interested in retro games? Then you might want to check some of my previous posts: this one, this one or perhaps this one. Pick your favorite.
