Looper Line brings the physics of real green reading to your fingertips. Analyze contour breaks, select your precise aiming line, control your stroke speed, and compete on daily-seeded courses. It's the ultimate practice partner for your short game.
Experience fully simulated lateral breaks and longitudinal uphill/downhill drag forces. Calibrated to match real-world STIMP ratings (Muni, Club, and Tour speed greens).
Fine-tune your stroke on a customizable practice green. Adjust putt distances, select green speeds (Muni, Club, or Tour), toggle visual slope grid overlays, and build consistent speed control.
Compete against putters around the globe. Play 'The Daily 18 Challenge' on a fresh course seeded daily, or race the clock to sink as many putts as you can in the 'Happy Hour Blitz' arcade challenge.
Compete for the top spot. Leaderboards are updated in real-time, allowing you to sync your scores to the cloud and compare your performance with putters worldwide.
Looper Line was engineered using the mathematics and physics that govern golf ball movement on real turf. Explore the resources and training fundamentals that inspired our putting simulation engine:
Explore practical training drills and advice focused on short-game mechanics, from tee gate setups to using visual rulers for perfecting putter face control.
Green Reading TechniqueUnderstand the biomechanical physics behind plumb-bobbing. Learn how to use your putter shaft as a gravity-aligned plumb line to visually read subtle green breaks.
Speed & Slope DynamicsAnalyze the mathematical differences between uphill and downhill putts. Discover how gravity, slope steepness, and friction affect capture speed and target line logic.
Kinematics & BiomechanicsDelve into a curated collection of academic research on human putting kinematics, SAM PuttLab measurements, ball-to-cup interaction, and green-speed physics.
