AI reference ratings are Easy 900, Medium 1300, Hard 1700, and Expert 2100. The Competition section opens the Player Profile, Rating History, AI Ladder, and Tournament Center. Tournament formats provide scheduled AI challenges and persistent standings. Completed games can be filtered by opponent/opening, game mode, and result. ONLINE v2.0.0 The Online Center includes lobby, challenge, spectator, reconnect, presence, chat, and online-rating framework. Without a configured Tronsoft online service endpoint the game runs in Offline Demo mode; all local chess features continue to work.
