About

Circle Master

Features
Read full description

Draw a perfect circle with one finger. Sounds easy — it isn't. Circle Master gives you one dot and one rule: draw a full circle around it in a single, unbroken stroke. Wobble, cut the corner or stop halfway, and your score drops. Nail it, and you get the number every player is chasing: 100%. HOW TO PLAY • Put your finger on the screen and circle the dot • Keep a steady pace — too slow and the attempt doesn't count • Don't stop, don't reverse, don't drift toward the center • Release, and see your accuracy as a percentage WHY IT'S ADDICTIVE One attempt takes three seconds. And you are always one percent away from your own record. "Just one more try" never means one more try. FEATURES • Instant scoring — accuracy in percent after every stroke • Global leaderboard — pick a nickname and climb the world ranking • 20+ achievements, from your first full circle to tricks you won't see coming • Hints and a sample circle whenever you need a reference • Clean, minimal design — nothing between you and the line • One-handed play, anywhere, in any spare minute • Five languages: English, Russian, Spanish, Dutch and Japanese Perfect for a break, a waiting room, or a bet with a friend over who has the steadier hand. How round can you go? Download Circle Master and find out.
