Forever ago, when I went to LTUE, I printed this free Co-op Train Game designed by Randy Cox. It seemed like a nice way to show the kiddos I hadn't forgotten them.
Of course, no one played the game until after I returned home. Sigh. But since then, it's become one of our favorites. And one of the few kids' co-ops that I know.
The essence of the game is to move about the board, pick up goods from the green spaces, and then deliver them to the appropriate yellow locations. Everyone works as a team trying to make the deliveries before the sun marker reaches the end of the day.
