Massive puzzle game overload! Gah, it hurts us, precious! From the unique and original Ynth to the physics-oriented Enigmo 2, there's something for every brainy gamer to enjoy. Unless you're really bitter and grumpy, in which case, I suggest eating an ice cream sandwich. No one can be grumpy while eating an ice cream sandwich.
Ynth - One of the freshest and most unique puzzle games I have seen yet on the iTunes App Store, this little title is somewhat incompletely described as a "jump and turn action puzzle game". You play a tiny bug trying to make it across pools of goop. By stepping into rectangular contraptions and pressing against their walls, you can rotate them to move towards the exit. Spikey things drop from the sky and like to roll around in your boxes, and sometimes you have to move back and forth to position yourself where you need to go. Text descriptions won't do it justice, but if you own an iPod Touch or iPhone, you owe it to yourself to give this game a try. A free Ynth Lite is also available.
Geared - If it has gears, I'll play it, and fortunately for Geared, it happens to be a great little puzzle game to boot. Drag and drop five sizes of gears onto the screen and arrange them so they connect the moving yellow gear and rotate all blue gears. It isn't as easy as it sounds (it never is!), and some of the later levels will have you scratching your head and nudging gears over pixel by pixel. A free Geared Lite is also available.
Enigmo 2 - The spectacular physics puzzle game Enigmo finally has a sequel, and this one really goes all-out to one-up its predecessor. Fully 3D with a rotatable, scalable, pannable view, your goal is to move water droplets (or other materials such as lasers) from its dispenser to the target. Using a variety of contraptions (including a few new ones like the teleporter and gravity inverter), place objects on the screen, rotate and adjust as necessary, and refine your Rube Goldberg-esque machination on-the-fly.
iEscaper - Room escape games are slowly making their way to the iPhone (see the Mystique chapters for more), and to be honest, I don't see why the App Store isn't flooded with them. The big touch screen is ideal for exploration and item management, and iEscaper makes good use of the technology to bring a short but satisfying point-and-click adventure to the palms of your hands.
