Perfect Circle

Read full description

Perfect Circle challenges you to do something that sounds simple but is surprisingly difficult, 'draw the perfect circle'. Watch the demo circle then take your turn and try to match it as closely as possible. You are not just judged on whether it looks right but on how well you control the entire motion from start to finish. Your performance is scored across three key areas: • Time – complete your circle as close to the 3-second target as possible. Too fast or too slow & your score drops. • Loop – how circular is your shape? The closer your drawing is to a true circle, the better your score. • Flow – how smooth was your movement? Sudden speed changes, jerks or hesitation will cost you. It is easy to understand, difficult to master and incredibly satisfying to improve. Every attempt pushes your precision, rhythm and control a little further. Compete against players around the world on the global leaderboard and see how your circle skills stack up. Features: • Simple one-touch gameplay • Unique scoring based on Time, Loop & Flow • Global leaderboard competition • Quick sessions with high replay value • A deceptively challenging test of precision and control How perfect is your circle?
