Train your brain with BrainSnacks®!

Every day we treat you to a new, unique visual brainteaser that will set your brain to work for a few minutes. Compare your personal score with the world score; you’ll know right away whether your brain is in top form.

Draw a line around the grid that passes through ALL the black and white dots before joining up with itself to make a continuous loop. Your line can pass through or turn left or right in empty squares, but there are rules for squares containing dots. Your line cannot cross over itself, branch off, or go through the same square twice.

There is a pattern behind the placement of the shapes and colours within the grid. Can you identify the pattern, and work out which of the squares below correctly fills the vacant space?
