I remember struggling with a similar grid puzzle a while back. At first, it seemed impossible to cover all the cells, especially with those blackened spots messing up potential placements. But after some trial and error, I figured out how to fit the tiles just right—kind of like when I was trying to buy tretinoin cream online and had to navigate all the different options to find the right one. Some grids just work out, and others? Well, they’re doomed from the start!
