How this lobby works
  • Online Match creates a server game another registered player can join.
  • Puzzle Game starts a clearly marked puzzle variation from puzzles flagged as online-offerable.
  • Solo And Local opens AI, AI-vs-AI, local PvP, and puzzle creation on one clean board.
  • Teach Mode is for finished games and annotations only, so live online games stay fair.
