Drag your colorful tail along to fill the entire level space in Logic Tail. Each tail starts off as a cube with an individual number on it. This number shows the amount of blocks the tail can move - so you must drag from the cube to full the entire space. Many levels have more than one tail that need to be stretched out - you'll just need to find the right order and combination.
