The winners advance to the next round, for which they must choose a different specialised subject. The winner of the final of the BBC version is declared "Mastermind" for that year and is the only contestant to receive a prize, in the form of a cut-glass engraved bowl. During Magnus Magnusson's tenure as presenter, the trophy was specially manufactured by Caithness Glass. A special guest would always be invited to present the trophy to the winner, with the exception of the final edition in 1997, in which Magnusson presented it himself.
