Extreme Memory Tournament

Memory League is a memory competition platform originally founded and created by Nelson Dellis and Simon Orton under the name Extreme Memory Tournament (XMT).

Memory League differs from traditional memory competitions in the fact that it is entirely digital, has head-to-head matches, and is composed of shorter disciplines. The five disciplines are one-minute memorization of names, words, images, numbers, and cards.

The first three world championships took place in San Diego, California in 2014, 2015, and 2016. The structure of the competition saw 24 of the World's top memorizers, including Alex Mullen (USA), Johannes Mallow (Germany), Simon Reinhard, Boris Konrad (Germany), Andi Bell (UK), Ben Pridmore (UK), Jonas von Essen (Sweden), and Yanjaa compete for up to USD $75,000 in prize money per championship over the course of three days. The fourth world championship was held online in January 2022.
