If you are a fan of virtual escape room games like me, Cool Math Games is a great place to spend your free time. If you are stuck with any of the puzzles in Escape the Black and White House, read my complete walkthrough below.

You start the game after falling asleep at home and waking up in a strange room, where everything is black and white. You navigate through rooms by clicking on arrows on the screen, while all objects you can interact with change the cursor into a hand.

Select the left or right arrow and then click on the boxes on the right side of the screen (a1) to find and pick up a Battery Pack. Also note the word BLOB written on the box on the shelf (a2).

Shortcut: You can use the image above to open the cabinet on the shelves (a3) to find some Fish Drops. You won't discover this code until later, but you can use it now.
