Domino Spiral Challenge

Night had set in, so I trotted inside from the deck and found a plastic box of colorful domino tiles tipped over on the floorboards! Instead of kicking them, I carefully stood each blue, yellow, and red tile upright on its narrow edge, curving them into a tight spiral. The real test was crawling backward on my hands and knees to set the final piece without knocking over the whole loop! My elbow wobbled, just brushing the carpet edge, but I slid the red tile into place with a gentle tap. The entire circle stayed standing! I sat back on my heels and threw both arms up in quiet triumph!
