Whether you’re teeing off or hitting down the fairway, the in game mechanics are fairly similar. To start off, check how far the hole is, if you’re on very easy to normal hit tab and it will show how far you’re going to hit and where your shot will land.
If you’re at the tee you’re most likely choosing the driver unless the course is short enough to reach the hole with a shorter range club. After you’ve selected your club click the circle at the bottom of the meter to start it, wait until it gets to the desired power, click it again, wait until it gets to the sweet spot (The green zone under the triangle where the meter started) and click it again. If all goes well you should get a nice shot.
