Namco created a PAC-MAN themed match three puzzle game for the iPhone and iPad to celebrate the thirtieth anniversary of their beloved pill-popping, ghost-chasing yellow hero. There's also a free flash version of the $2 iPhone game.
Is "Match three puzzle game" on the road to being a genre? I never thought about it but a lot of puzzle games do involve matching 3 of something, it seems likely it could become a general genre term :p
"Puzzle" itself isn't very descriptive at all, but "match three puzzle" tells us with it is in only 3 words! :D
