Katharsis

Katharsis was a form of gambling seen on the planet of Telos during the reign of Xanatos. It involved betting on a series of sporting events. Betters were eventually narrowed down to a core group, who bet on the final challenge.

Obi-Wan Kenobi and Qui-Gon Jinn exposed a plot by UniFy and Offworld Mining Corporation, which involved pre-selecting the Katharsis winner and forcing that person to donate half of their earnings to the corporation.
