Sofia Hartmann joined PlayOnStake as a promotions analyst after spending three years in affiliate marketing for several European iGaming networks. Her obsession with value-per-deposit ratios and fine-print wagering requirements quickly made her the team's go-to expert for all things bonus-related.
Every week, Sofia reviews dozens of crypto casino offers — welcome packages, reload bonuses, free spin deals, no-deposit codes and cashback schemes — so players can instantly identify which promotions are genuinely worth claiming and which ones are marketing fluff. She has a particular talent for decoding complex wagering terms into plain language.
Sofia is a strong advocate for transparent bonus practices and works closely with casino operators to highlight any misleading terms she uncovers during her research. Outside of work, she is an avid poker player and holds a degree in Business Mathematics from the University of Vienna.
