Tip # 1: Concentrate on putting.
Miniature golf is a game of putting, which means there are no long strokes. Practice your putting; keep your feet steady, swing from the shoulders and keep the face of your putter square.
Tip # 2: Focus on the hole.
Miniature golfing courses are famously crowded with windmills, waterfalls, pendulums, and all kinds of obstacles that prevent your ball from reaching its intended destination. Maintain your concentration as though there were no elaborate castle drawbridge or screaming children.
Tip # 3: Walk the course.
Try to walk the mini golf course and look for traps and obstacles that can be avoided -- this is particularly true of adventure mini golf. If you can't traverse the course on the day, many courses have online walk throughs that can prepare you before you enter the course.
Tip # 4: Help the little ones.
Even though it might be satisfying to mercilessly crush your opponents on the put-put course, it's really all about having fun. If you are accompanying children on a day of mini golf, do your best to help them on the difficult obstacles.
