Eliminate Blocks

A picture made of colored blocks will appear on the levels in front of you. Brown cannon blocks are placed around the perimeter. Each of them can only fire once. Your task is to shoot all the blocks. This is an important sequence of shots. Examine the location, pay attention to the location of the cannons and determine which one will start first. Please note that blocks will appear in the future. Not to be touched, they feature black skulls in Eliminate Blocks.
