Map Puzzle has a variety of simple geography games where players are shown the physical outlines of states, provinces, countries, etc., while at the same time you’re given the names and accompanying puzzle pieces that belong there.
I learned about it at a post in Google Maps Mania.
That same post shared another site – called Jigsaw Explorer. There, students could create their own jigsaw maps that their classmates could play.
I’m adding these resources to The Best Online Geography Games.
