Puzzle

I had been hooked on playing "Draughtboard Puzzle" for pleasure in the evening for a while. This classical box design is nice, isn't it? It's a simple puzzle to arrange the pieces to make a standard 8 by 8 checkerboard. It really looked easy, but it's difficult. I had struggled with it, and my bf couldn't watch me any longer, and we cheated... Oops. It was nearly completed, but I am a jellyfish (means I came close but didn't complete it!)...
