## Description

Sort 21 numbered balls 1–21 by sliding and flipping. Beat your best score!

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?
