I'm sorta hooked on a couple freemium iOS games right now:
Marvel Puzzle Quest: Dark Reign, which is a great match 3 VS game, where you collect comic book covers to improve the powers of your various Marvel characters and then level them up. Still in beta-ish, so they're tweaking characters a bit, sometimes dramatically. A lot of Wolverine (Astonishing) and Thor fans are pissed about the latest round of nerfs, but the Spiderman (Classic) fans are a bit happier.
and Knights and Dragons, which is sort of a kingdom sim with dungeon battles, boss battles, and VS battles. Kinda tries to do everything, which means there's usually enough going on to keep me busy.
Anyone here want to share a referral code for Knights and Dragons? Here's mine:
