Instead of only having to separate two colors of square, there are three or even four colors present that all have to be separated into different sections. The colored squares puzzle is a variation of the black and white squares puzzle. Continue to find the boundaries where white squares touch black squares, separate them, and you can safely ignore groups of the same color. Later in the game you’ll notice that these black and white squares will be grouped in complex ways. Squares of the same color can remain in the same region of the solution. As seen above, the paths cut between the black and white squares before heading to the endpoint. What you need to do to meet the requirements of this puzzle type is use your path to separate any black squares from adjacent white squares. The white and black squares puzzle is frequently encountered, especially as it evolves into more complex variations later in the game.

It might seem impossible at first, but you’ll figure it out in time. Later in the game if you see a puzzle that has a black dot on every single grid, you may be surprised to learn that you have to path through the entire puzzle board in order to complete it.

In the image above you’ll notice that four black dots are left uncleared, resulting in an incomplete puzzle. When you see black dots on a puzzle board, what you must do is ensure that your path from start to finish overlaps all of these dots.
