Shock Block.

In a world of advancing multi-coloured blocks... Where the only way to destroy them is to arrange them in groups of at least four... You are the only hope.

You never wanted this. You wanted a simple life with your family. But that all changed when the blocks came. They advanced in rows of ten consuming all in their path. At first the scientists were at a loss but they eventually found a way to fight back... rearrange them so they connect into groups of at least four and then... BOOM.
