A few light up. Then everything shuffles.
A few identical balls glow for a moment, then they all go dark and start darting, wobbling and bouncing off each other. Keep your eyes on the marked ones and, when everything stops, tap them back out. Every clear adds speed, and every third level another ball to track — up to six at once. Three wrong picks and you’re out. Free, no sign-up — play right in your browser.
