• Open
  Open to any eligible player.   Most are tough.
• Mini Mon
  Open to players of lower Mon grade, usually up to 6th Mon, but sometimes up to 9th Mon.   A good choice for younger players, but the standard can still be high.

Junior competitions are also usually restricted according to age, grade, or both age and grade.
