Here are three cool games prepared by students of my 2020 Game Theory class. Enjoy! (More games will come later. See this post for an earlier game.)
Four-in -a-row with HEX board by: Daniella Drori, Margot Guetta, Eyal Magen and Aiden Platt
Playing 3-player coalition games by: Barak Aharoni and Boris Borshevsky
Update: If you find it easy to win in the Four-in -a-row with HEX board game challenge yourself: To force a win with m-in-a-row line, for m=5,6…? To force as many as possible winnings moves.
