Leon Sturm is a German professional poker player and a rising superstar in the international high-stakes community. A WSOP bracelet winner and EPT High Roller champion, Sturm has rapidly ascended from a dominant online “prodigy” under the handle “Rumukulus” to a top-tier regular in the world’s most exclusive live tournaments.

Career Earnings & Biggest Results

With total live tournament earnings surpassing $11,017,000, Sturm currently ranks #12 on Germany’s all-time money list. His career-best live score of $1,689,913 was achieved in August 2025 with a victory in the European Poker Tour (EPT) Barcelona €100,000 Super High Roller.

Sturm famously captured his first WSOP bracelet in 2023, winning the $50,000 High Roller for $1,546,024 at just 22 years old. He has remained in elite form through 2025 and early 2026, recently finishing 3rd in the 2023 WSOP Paradise Ultra High Roller for $1,322,000 and 5th in the 2025 EPT Monte Carlo Super High Roller for $624,065. His massive online pedigree and live consistency contribute to an estimated poker net worth of over $12 million.

Biography & Poker Background

Born in Germany in 2000, Sturm built his reputation as an online “end boss” under the legendary handle “Rumukulus”. Long before he was a fixture on the live high-roller circuit, he was feared across platforms like GGPoker and PokerStars, winning the 2022 World Championship of Online Poker (WCOOP) and the 2023 GGPoker World Festival Super Million$ for over $1.5 million.

Sturm’s rapid rise has drawn frequent comparisons to fellow German phenom Fedor Holz. He transitioned to live poker in 2019 and quickly established himself as the youngest regular in “nosebleed” stakes. Currently residing in Vienna, Austria, a hub for elite German pros, Sturm is known for his professional discipline and has recently become a coach for GTO Lab, sharing his high-level insights with the next generation of players.

Play Style & Strategy

Sturm is renowned for a “highly technical, solver-backed, and GTO-centric” play style. His strategy is rooted in modern game theory, but he is equally praised for his “feel” and intuition, which he has honed through millions of hands played online. He is a master of navigating “capped ranges” and applying extreme ICM pressure in high-stakes final table scenarios.

His approach is characterized by a “limitless” mental state and a disciplined routine, often incorporating morning study sessions and structured breaks to avoid burnout. Whether navigating a Triton Poker Series field or the deep stages of the WSOP Main Event, Sturm’s strategy revolves around technical balance and a relentless ability to remain focused during the game’s most expensive pots.
