Yes, you can putt on a golf simulator. Most golf simulators have sensors that can detect the movement of the putter and the ball, allowing you to simulate a putt on a virtual green. Some golf simulators even have specialized putting mats and sensors that can provide detailed feedback on your putting stroke, such as your clubface angle, swing path, and impact speed. While putting on a golf simulator may not be exactly the same as putting on a real green, it can be a useful tool for practicing your stroke and getting a feel for different green speeds and contours.
