5. Shape Shift HD (iOS)

See how far all that visually intense, CPU-proficient junk got you? (Answer: Not very). But you’ll have plenty more fun with the slight blast from the past that is Shape Shift HD. Backflip Studios’ free (yes, we said free) game is a lot like that gem-swapping legend Bejeweled, except you can move pieces anywhere on the board. It’s not all that challenging, and past the neverending Zen mode and an only slightly challenging Classic mode (which basically just adds some sporadic and easy-to-stop bombs), there’s not much to do here. But hey, we could think of worse ways to spend —oh, that’s right, nothing.
VERDICT: Almost good enough to make those in-game ads worth the annoyance.
