My wife and I first learned of Mexican Train 6 weeks ago while visiting friends in Nova Scotia, Their game was the double 12 version and after playing a few games we knew we had to find our own game. Up until I found the Well.ca site all that either of us could come up with was the sets that had to domino dot stile of dominos, not what we wanted. The number stile is our choice. Playing the double 18 version opposed to the double 12 is quite a bit more fun and challenging and thegame is a big hit in our home when friends or family come calling. It cetainly is a game for the whole family and age groups.
