GDC has begun and the new previews are starting to flow. To start off, IGN have a new preview with the upcoming "Brain-Age-esque" game by Gameloft - Brain Challenge.

Your gray matter will be run through the paces with 20 mini-games. The GDC demo only showed five of these stress-inducing tests. The Daily Brain Test features a mix of simplistic and somewhat taxing exercises. For each, you will need to use only the left thumbstick (or D-Pad) to highlight the correct items and A to select. Each test gives you 50 seconds to answer as many items as possible. The exam gets progressively harder. Things get a tad more stressful when the counter hits ten seconds, as the controller vibrates violently as incentive to hurry the hell up. It can get quite nerve-racking.
