Three days in San Diego
The 2016 Extreme Memory Tournament ran from 24 to 26 June in San Diego. The UB Post, reporting on 30 June, described the field as “the top 24 memory athletes of the world” competing across five categories: names, cards, images, numbers and words. The total prize fund was $75,000, divided $20,000 for first place, $12,000 for second and $6,000 for third.
Purevjav, identified by the paper as a grandmaster of memory, reached the final and lost it to Simon Reinhard of Germany, described in the same report as the world's fifth-ranked athlete and a world champion. Second place carried $12,000. In a tournament built around raw speed rather than endurance, it was the deepest run of the week by any competitor except the champion.
The quarter-final against Alex Mullen
The match that defined the tournament came earlier. In the quarter-finals Purevjav faced Alex Mullen of the United States, who had won the world memory championship in 2015 and was, at that moment, the dominant figure in the sport. Purevjav won 4-3.
The UB Post called it the most sensational victory of the tournament, and the description is not hard to justify: one game separated the reigning world champion from an early exit, and it fell the Mongolian's way. The report does not record which of the five disciplines decided the seven games, or the margins within them.
The Mongolian five
Purevjav did not travel alone. “A total of five memory athletes of the Mongolian Intellectual Academy competed in the XMT 2016,” the paper wrote, and two of them finished on the podium. Tsetsegzul Zorigtbaatar, listed as an Asian master, took bronze by beating Germany's Johannes Mallow 4-1, Mallow being the top-ranked athlete of the period and the winner of the 2015 Extreme Memory Tournament.
Two of the three medals in San Diego therefore went to athletes from the same Ulaanbaatar academy. The paper headlined its account accordingly: Mongolia conquers Extreme Memory Tournament 2016. For a country of roughly three million people, taking silver and bronze at an invitational limited to two dozen competitors is the kind of result that gets a newspaper front page at home and almost no coverage anywhere else.
What the tournament asks of a competitor
The Extreme Memory Tournament is not the same test as a classical world memory championship. Where the championships run long disciplines over several days, the XMT as described by The UB Post is built on five short categories and resolved through direct matches between two competitors, from the quarter-finals to the final.
That structure rewards a particular profile: speed of encoding, immediate recall, and the nerve to repeat both under match pressure several times in an afternoon. A 4-3 scoreline of the kind Purevjav produced against Mullen exists only in a format where individual games are short enough to be won and lost repeatedly inside a single contest.

The firm record is the result: silver at the 2016 Extreme Memory Tournament, a 4-3 quarter-final win over Alex Mullen, a final lost to Simon Reinhard, $12,000 in prize money, and membership of the Mongolian Intellectual Academy, all reported by The UB Post on 30 June 2016. The paper also gives his grade in the sport, grandmaster.
Almost everything a reader wants next is absent. No date of birth or age appears in the source, no school or coach, no training description, no interview, and no account of what he has done since 2016. His name is rendered two ways — E. Purevjav in Mongolian style, where Purevjav is the given name, and Purevjav Erdenesaikhan in Western order — which matters for anyone tracing later results.
