Game: Pac-Man S

It may be time for all the other Facebook developers to go home (barring, perhaps, PopCap). In terms of concept, Pac-Man S is such a perfect Facebook game that it's hard to imagine how anything else could compete. Pac-Man S uses a Bejeweled Blitz-like format where you attempt to get the highest score possible in two minutes of play. As your score increases, the game becomes faster-paced and more challenging. Players can opt to spend a virtual currency called points on up to two power-ups from a group of four to customize the experience.
