NES Open Tournament Golf featured three different courses. Those courses were the US Course, Japan Course, and the UK Course. Although the Japan Course and UK Course are also playable courses in Mario Open Golf they do not contain the same holes. There are some holes in each course that are identical or nearly identical to holes found in NES Open Tournament Golf. For example, hole number one in the Australia Course is hole number nine in the US Course. Mario Open Golf featured five different courses. Those courses were the Japan Course, the Australia Course, the France Course, the Hawaii Course, and the UK Course. In addition to those five courses an Extra Course is also available. The Extra Course contains a mix of holes from the other five courses.
