Prior to last night's League of Legends World Championship semi-finals, Riot released the findings of their investigation into several potential instances of cheating during the quarterfinals.  The most severe instance of rule violations fell on Azubu Frost player Woong, whose actions of looking at an above booth mini-map resulted in a strategic advantage for his team. As punishment, Azubu Frost is fined 20% of its winnings from defeating Team Solomid and advancing into the semifinals -- $30,000 of $150,000.

Four other events of above booth mini-map viewing resulted in warnings issued to the participatory teams and players. These four instances include WE WeiXiao during the CLG.EU vs. WE game 3,  iG Zzitai during the SK vs. iG game, TSM Dyrus during the TSM vs. AZF game 1, and TPA Stanley during the TPA vs. Naijin game 2. Riot's investigation found that each of these rule violations resulted in no direct gameplay advantage for the player or their team.

The above booth venue screens that showed each team's mini-maps will remain for the League of Legends season 2 finals between Taipei Assassins and Azubu Frost, but Riot has built an overhang so that players will be unable to look at them. Riot has also promised a higher diligence in the future, so events like this won't happen again. The finals resume Saturday, October 13 at 7PM PDT.
