Marvin Rettenmaier (often nicknamed “Mad Marvin”) is a German professional poker player and a former Global Poker Index (GPI) #1 ranked player, widely recognized as one of the most successful tournament grinders in the history of the game.

Career Earnings & Biggest Results

With over $7.4 million in total live earnings (according to The Hendon Mob), Marvin Rettenmaier is a titan of German poker history. His career reached its absolute peak in 2012 when he accomplished a feat unmatched at the time: winning back-to-back World Poker Tour (WPT) Main Events.

First, he took down the $25,000 WPT World Championship at the Bellagio for $1,196,858, his largest career score. Just months later, he flew to Cyprus and won the WPT Merit Cyprus Classic for another $287,784, solidifying his place in the record books.

He also holds a major European title, having won the EPT Monte Carlo High Roller in 2012 for nearly €365,300. While his volume has decreased in recent years compared to his prime, he remains a legend of the mid-2010s era with 16 tournament titles to his name.

Biography & Poker Background

Originally from Leonberg, Germany (and later residing in London), Marvin Rettenmaier was one of the faces of the “German Invasion” of high-stakes poker. Known for his outgoing personality, guitar playing, and “party” lifestyle, he earned the nickname “Mad Marvin.” He served as a sponsored Team Pro for PartyPoker during the height of his career.

In recent years (2024–2026), Rettenmaier has stepped back from the relentless full-time grind, though he still makes occasional appearances at major festivals like the WSOP in Las Vegas, recording cashes in 2025 events.

Play Style & Strategy

Marvin Rettenmaier was a pioneer of the loose-aggressive (LAG) tournament style that dominated the 2010s. Known for playing a high volume of hands and applying constant pressure, he excelled at accumulating chips in the middle stages of tournaments without waiting for premium holdings. His ability to switch gears and close out tournaments was evidenced by his incredible 2012 run, where he seemingly could not lose a major flip.
