The goal is to prevent the blocks from reaching the top. Using the touchscreen, you can eliminate three or more like-colored blocks grouped together. Strategize to make big groups and you'll get multipliers – two times the points for six blocks, three times for nine, etc. The twist is that there are only so many touches allowed per level."
