The JHBS (Jens Schulz Half Ball Supercup) is a Half-Ball tournament organized by the IWHBC. For information about the future formation of the HBDB (Half Ball Decision board), go here

​

The game Half-Ball (not to be confused) is a sport considered to be created by Amund Williams and Jens Schulz. As they layed out most of the basic rules.

The first Supercup was in June 13, 2021, but was solidified as a regular event in July, as that is where the second Supercup took place. This is also when the rituals were layed out.
