Store description excerpt
A deceptively simple puzzle that's fiendishly hard to master. Twenty-one numbered balls sit on a looping track. Your goal is simple: put them in order, 1 to 21. But there are only two moves — slide the whole loop around, or flip the four balls trapped under the turntable. Getting every ball into its place takes planning, patience, and a bit of clever thinking. Easy to learn in seconds. Genuinely satisfying to solve. Impossible to put down. HOW TO PLAY • Slide: drag the track (or tap Left / Right) to rotate every ball around the loop together. • Rotate: flip the four balls inside the yellow turntable to re-order them. • Solve the loop 1–21 in as few moves and as little time as you can. FEATURES • One-more-go puzzle action that's perfect for quick breaks • Track your best moves, best time, and averages over every game • Your progress is saved automatically — pick up right where you left off • Smooth, colorful, and relaxing • 100% offline — no internet, no account, no sign-up • No ads, no in-app purchases, no tracking • Free Whether you're a puzzle veteran or just looking to unwind, 21 Ball Challenge will keep you coming back to beat your personal best. Can you solve it in the fewest moves? A free game from AI Workforce Solutions.
