Read the Green.
Dial in Your Speed.

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.

Core Features

Designed for Real Putters

Realistic Slope Physics

Experience fully simulated lateral breaks and longitudinal uphill/downhill drag forces. Calibrated to match real-world STIMP ratings (Muni, Club, and Tour speed greens).

Practice Green

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.

Group Games

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.

Global Leaderboards

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.
