Normally used to settle ties, the Bonus Hole is more of a feat of strength than a true hole. From Hole #20's pin, you must throw your disc UP and OVER the walkway. Yep that tiny gap up there.

If it is used as a tie breaker, players must then return the disc back to it's hole in the plant box. Lowest score wins. Booyah!

That's it man. Go play already.
