NES Open Tournament Golf (Mario Open Golf in Japan) is a NES (Famicom in Japan) video game staring Mario, Luigi, Princess Peach and Princess Daisy (The latter two being the caddies, who will offer you advice). The game has three different courses, which were featured in Japan, United States of America, and the UK.
The gameplay is quite similar to Golf on the NES. The objective of the game, as in every golf game, is to get the golf ball into the hole. To do this, you'll have to use a wide range of different clubs, each one having an advantage over another. Scattered throughout each hole are hazards such as sand pits and small ponds that will affect your play.
