my favorite games are moonlight mahjong, the best mahjong I've played. the magic blackboard, a brick break game with tons of content made by the same people who made snailmail, which is another good game. adrenaline, which is 30 one minute mini games that are good time killers. cell splat boozle, an interesting spin on match 3 games lock n roll, a pokerish type dice game orba not sure if all of these would be considered indie games? they're not major like from ngmoco, gameloft, etc. they're all extremely fun games with bright graphics.

For Match-3: Try Smiles! One of the best match-3 out there. And Puzzlings. All other recommendations of myself are already mentioned . Hmm. Maybe Pinball Fantasies?
