Some games may support the learning of mathematics in one way or another. It is important, however, to identify the educational component in a game as playing it, by itself, may not lead to further learning. The linked document offers an analysis of the mathematical potential in Tic-tac-toe through the lens of the RaPID model: https://network.structuringinquiry.com/wp-content/uploads/sites/7/2020/06/Tic-Tack_Toe.pdf
