Mariano Locascio

Born in Rosario, Argentina, around 1995/1999, Mariano Grandoli moved to the United States at age 16 to study Business and Economics at California State College. He discovered poker at 19 and launched his YouTube channel in February 2019, initially playing $1/$2 and $1/$3 games at casinos like San Manuel in Southern California.

Grandoli gained widespread recognition through live streams on Hustler Casino Live, where his aggressive play and big bluffs earned him the moniker "King Argentina." He also became a regular at The Lodge Card Club and other Texas-based streams. His YouTube vlog, now with over 200,000 subscribers, documented his meteoric rise from low-stakes grinder to high-stakes crusher.

Unlike many pros, Grandoli focuses exclusively on live cash games, with no recorded tournament cashes. His aggressive, pressure-heavy style is balanced by disciplined folds and table control. He is known for large bluffs but also demonstrates the ability to make prudent laydowns.

In 2024, he won $486,200 over 485 hours (roughly $1,000/hour). His 2025 results were even more staggering: $1,257,000 in 557 hours across 92 sessions, earning an hourly rate of $2,256.73. He described this as his best year ever.

Grandoli is one of the most popular poker vloggers, alongside Rampage, Andrew Neeme, and Brad Owen. His measured, articulate commentary sets him apart. Despite his fame, he keeps his personal life private; little is known about his family or pre-poker background. He also launched a passion project band in 2025.

Mariano Grandoli's journey from $300 buy-ins to seven-figure cash game profits serves as an inspiration for aspiring players. His aggressive style and vlogging success have influenced a generation of poker content creators, proving that disciplined, high-aggression play can yield extraordinary results in live cash games.
