One-on-one Sit&Go games, games at private tables, Omaha and event modes, such as Royal Holdem or Jokers do not count towards achievement progress and don’t register in your gameplay stats.
The one-on-one Sit&Go games and games at private tables are not included in order to prevent cheating.
The other modes imply higher chances to meet the medal requirements, and since we want everyone to earn them without any advantage over other players, most medals are earned only in a standard Hold’em game.
