Alternate Endings: This is more of a video "Choose Your Own Adventure" than anything else, good for a quick bus trip. But it is a nice throwback to the days when full-motion video games were considered cutting-edge. Ah, Night Trap, I miss you.
Adventure: The classic Atari 2600 game, on your iPhone. It's a little twitchy, but hey, it's free.
Blackbeard's Assault: Match cannonball colors and keep them from hitting the X. If you've ever played Zuma, you'll feel right at home.
Booty Blocks: What is it about pirate puzzle games? Flick booty around the screen with your fingers.
Word Warp: Here's a quick little vocabulary game, kind of like what you'd see in the newspaper--if you still read newspapers.
Enigmo: In this brain bender you use objects to angle water drops and solve puzzles.
Aurora Feint--The Beginning: It's an online role-playing puzzle game! If you're a fan of Puzzle Quest, you'll get hooked on Aurora Feint. Consider yourself warned.
Is that all? No, there are plenty more games where those came from!
