Welcome to Nail Stack Run Challenge, our quirky nail salon for nail extensions and coloring. Run your finger along the route, collecting nail pieces that increase the length. Brushes with varnish will apply paint, and passing under the taps, from where multi-colored sparkles pour out, will add brightness and sparkle to the nail. But be careful and carefully avoid sharp saws, which will instantly snatch off everything that has been built up. The longer the nail, the more difficult it is to move and avoid obstacles in the Nail Stack Run Challenge.
