Today only, LabPixies has Line Up 2 (iTunes Link) in the iTunes App Store for FREE for a limited time. Deal expires April 22, 2010.

Line Up 2 is a fun color matching game! Click on blocks of 3 or more of the same color, as quickly as you can, before they overflow the board. But be careful! You only have 100 taps for each speed cycle. The more blocks you remove at one click, the higher score you get!
