Portuguese (or Podagee) horse shoes were created years ago in Hawaii, out of the love for the original game of horse shoes.  When a sand pit and stakes were not allowed, an old time favorite evolved.  Large washers take the place of horseshoes, and a wooden box with a hole in the center (known as the cup) substitute for a horseshoe pit.  Podagee horseshoes has been a long time family favorite at nearly any event in Hawaii.  
 
This game is also known as "Washer Toss" outside of Hawaii.
