The Match Master, aided by a pair of assistants, functioned as the official referee for games of limmie. This individual was responsible for judging plays, determining offside calls, and confirming the validity of scores. In 13.3, a Roonan held the position of Match Master within the BlasTech Gikosphere on the planet of Coruscant. This Roonan disrupted a match during the opening round of the Galactic Cup of Limmie, a game that saw representatives from the planet Fondor facing off against Coruscant's team. The HoloNet News, in its CoCo District edition, featured an article that cast doubt on the Match Master's call to halt the game when its conclusion seemed practically inevitable.
In 19 BBY, Parja Bralor, a woman, officiated as Match Master in a game contested between clone stormtroopers and Mandalorians.
The first appearance of a Match Master was in the article Coruscant Eliminated in Galactic Cup Opening Round, authored by Pablo Hidalgo and Paul Ens, with illustrations by Joe Corroney. It was featured in HoloNet News Vol. 531 47 on the HoloNet News website and released on March 14, 2002.
