Out of Bounds



When a player gets an O.B., it means that their golf ball landed Out of Bounds. This is an event found in the Mario Golf series. When the player hits the ball where it lands outside of the boundaries, falls off the edge, lands in lava, in a Chain Chomp pit, or elsewhere that is not in the main course, it is qualified as an O.B.. Some sort of signal usually appears when the player gets an O.B. to let them or her know that they will be penalized. The penalty for an O.B. is one stroke.

Water Hazard
The Water Hazard is another type of O.B.; this event only occurs when the player's golf ball lands in a body of water. The penalty for a Water Hazard is exactly the same as a regular O.B., thus why it is classified as an O.B..

Trivia

 * In Mario Golf 64, Toad is the one to alert the player of an O.B.. In Mario Golf: Toadstool Tour, a Koopa Paratroopa is the one to alert the player.
