06.11.2026. New game on MathGames: Roadworks, by Georgy Nuzhdin. A city full of roadworks: players take turns closing a crossing, and whoever cuts A off from B loses. With no other rule, on a 3×3 board the first player always wins (why?); once dead ends close by themselves there is real strategy, and the unsolved 5×5 board is meant for classroom competitions. With 30 challenges and a slide deck for teachers.
