• A. Sprague–Grundy theorem chosen
  The Sprague–Grundy theorem is a fundamental result in combinatorial game theory that assigns each impartial game position a nonnegative integer (its Grundy value), allowing such games to be analyzed and combined via nim-like addition.
• B. Winning Ways for your Mathematical Plays
  Winning Ways for your Mathematical Plays is a multi-volume book on combinatorial game theory that popularizes and systematically explores mathematical games and their underlying structures.
• C. Conway’s games
  Conway’s games are a class of combinatorial games introduced by mathematician John Horton Conway, forming the foundation of surreal numbers and studied for their rich algebraic and strategic properties.
• D. The Dots and Boxes Game: Sophisticated Child's Play
  "The Dots and Boxes Game: Sophisticated Child's Play" is a mathematical analysis of the classic pencil-and-paper game Dots and Boxes, exploring its underlying combinatorial game theory and advanced strategies.
• E. Wythoff Nim
  Wythoff Nim is a classic impartial combinatorial game involving two piles of tokens, whose optimal play is characterized by positions related to the golden ratio.
