• The article discusses the unlikely game of "Hexapawn," a simple game that was created by Martin Gardner in 1962. Hexapawn is played on a 3x3 grid, with each player controlling three pawns. The objective is to be the first player to move a pawn to the opposite side of the board.

• Despite its simplicity, Hexapawn has some fascinating properties. It is a game of perfect information, meaning that both players have access to all the relevant information about the game state at any given time. Additionally, Hexapawn can be solved using a simple learning algorithm, which allows a computer program to learn the optimal strategy and eventually become unbeatable.

• The article highlights the educational value of Hexapawn, noting that it can be used to introduce concepts like game theory, artificial intelligence, and machine learning to students. By playing and analyzing Hexapawn, students can gain a deeper understanding of the principles that underlie more complex games and decision-making processes.
