Enrico Marraffa

Enrico Marraffa is a mental from Italy. Enrico Marraffa won the International Association of Memory world championship in Lund in 2024 and holds the IAM five-minute random images world record of 775 points, set at the IAM French Open Memory Championship in 2025.

Competitive mental calculation is governed and measured: the Mental Calculation World Cup, the Memoriad and the Mind Sports Olympiad all run standardised tasks — adding ten ten-digit numbers, multiplying eight-digit numbers, extracting square roots and computing calendar dates — so results are directly comparable across decades.

What separates a documented record from a family anecdote is that someone else wrote it down at the time. Enrico's is recorded in published reference sources, with a date and a figure attached, and that is the standard applied to every entry in this index. Where an age or a date is disputed in the sources, this page follows the published record and says so rather than choosing the more impressive number.

Records like this one rarely survive untouched. The age thresholds that define early achievement keep falling as training methods, coaching and access to competition spread to more countries, and each generation of mentals reaches the standard a little sooner than the last. Whether Enrico's mark has since been beaten is noted above; the achievement itself is fixed to its date and stands on the record as it was set.
