What is the oldest board game for 3 or more people? The oldest one I'm aware of is Halma from 1883 or 1884. Interestingly, Chinese Checkers was supposedly derived from it a few years later, even though that game came from Germany, not China.
Anyway, 1880's is pretty modern. I'm hoping there's some much older, maybe even ancient, board game for 3 or more people.
For it to be a board game, it has to involve a board space in which pieces are placed or moved around. So no card games, and no dice games like yatzee.
