Riot Games has delivered a significant competitive ruling targeting four professional competitors from Greece’s premier League of Legends circuit. These athletes faced sanctions for deliberately altering match outcomes throughout the 2019 Winter Split and subsequent 2020 Spring Split competitions.
The implicated roster includes Grigoris “Kobazz” Kovalegos, Panagiotis “Tython” Kobothekras, Thanasis “Tanacee” Vlahogiannis, and Vaios “Lunny” Dimzas. Investigators confirmed each participant engaged in coordinated efforts to distort competitive results, primarily motivated by monetary benefits derived from wagering activities and intentional underperformance.
All competitors received permanent exclusion from any Riot-sanctioned tournaments. Evidence revealed the manipulation affected no fewer than four separate matches spanning both competitive periods, with Riot coordinating the inquiry alongside Greek Legends League administrative personnel.
“Match outcome manipulation devastates the competitive fairness of our esports landscape and damages the standing of the League, competing organizations, and professional athletes collectively,” Riot declared in their formal announcement. “To safeguard the European competitive gaming environment, we maintain and will persist in enforcing absolute intolerance toward such conduct while continuing collaboration with our betting integrity partner Sportradar and appropriate European regulatory bodies to implement necessary decisive measures.”
According to the official findings, all four athletes breached ERL regulation 8.1.2. This provision addresses all forms of collusion, characterized as “coordinated efforts or conspiracies to cheat or mislead others. Such arrangements can materialize between Competitors, Squads, and/or Franchises, typically executed exclusively for the advantage of participating entities.
Three participants additionally contravened regulation 8.2.15, prohibiting any team affiliate or league representative from direct or indirect involvement in wagering or gambling activities concerning matches or results. Officials determined this violation occurred because the match interference was orchestrated by players seeking personal financial enrichment.
While competitive result manipulation represents an infrequent occurrence within League of Legends ecosystems, when identified it produces severe repercussions for implicated individuals. The consequences extend beyond participating athletes, creating substantial challenges for involved leagues and jeopardizing the credibility of the entire competitive gaming industry.
The 2019 competitive season witnessed a major match-manipulation controversy within China’s LPL division. Former LGD Gaming jungler Xiang “Condi” Ren-Jie and team manager Song “Hesitate” Zi-Yang both received sanctions for engagement in match-fixing and gambling operations. Condi incurred an 18-month competitive suspension, while Hesitate faced permanent exclusion from professional circuits.
Industry analysts note that match-fixing typically emerges in regions with less established regulatory oversight and where player compensation remains inconsistent. Prevention requires robust monitoring systems, comprehensive player education about integrity standards, and transparent reporting mechanisms for suspicious activities. Organizations must implement regular audits and maintain partnerships with specialized integrity services like Sportradar to detect irregular betting patterns that often expose manipulation attempts.
