It depends on the system. Usually, the courses may be entered to play. The exception applies to the Eternit system. Eternit courses may not be entered as they can be easily damaged. If the courses are not allowed to be entered, this is usually posted on the facility or even directly on the courses themselves.

If you want to start mini-golfing as a hobby, a beginner's set is a good investment – with a club, a selection of balls, and a practical bag, you'll have everything you need. With it, you can try out different playing styles on the course, practice how to get a hole-in-one (completing the hole in one stroke), and continuously improve your score.

If you've really caught the bug, joining a club is the next logical step. There are mini-golf clubs all over the place where you can get an official player number and participate in tournaments. Most clubs also offer weekly training, which is a great way to further develop your game and meet new people. From there, it's not far to league play with the club team.

Mini golf balls differ primarily in their hardness, speed, weight, size, and surface. These properties influence how the ball rolls, bounces off banks, and can be controlled. Additionally, balls react to temperature, which affects their behavior. Therefore, players use different balls depending on the course and situation to achieve desired results.
