How's this for a theme: three games that make you scratch your head! Colorbind because you can't figure out how to do what's right in front of your face. Gravity because you can't figure out how to precisely set up a chain reaction to tap a little button. And NOBY NOBY BOY because you have no earthly idea what's going on (even though you love it).
Colorbind - A beautiful puzzle game that is deceptively simple in appearance. Your goal is to extend colored ribbons across the screen to join like-colored dots together. You can only turn at right angles, and ribbons cannot cross at a fold, creating some fantastically challenging puzzles that can only be solved once you really "get" the game. Lots of levels and three difficulty settings make this one full of content to devour.
Isaac Newton's Gravity - A wonderfully complete physics puzzle game with a lot of precise head scratchers. Place various objects on the screen, ranging from boxes to balls to girders and more, then tap the "play" button to set things in motion. Your goal is to nudge a button on the stage, and the only momentum you're given is by a ball that drops out of the wall.
NOBY NOBY BOY - Come on now, say it like you see it: NOBY NOBY BOY! With loud exclamatory voices! This gem of a game comes from Keita Takahashi, creator of the Katamari Damacy series, and is based on the PlayStation Network title of the same name. Rather than putting a quirky game in front of your face, NOBY NOBY BOY is more like a wildly interactive toy. The "goal" is to stretch the main character (the "boy") out as long as you can so he can add his length to the cosmically-proportioned "girl" in the hopes that she can unite all things in the galaxy. Yep! Wholly unique when compared to its PSN cousin, and wholly unique when viewed by itself. It's so absolutely charming you can't help but love it.
