The game Mexican Train has nothing to do with Mexico, it was actually developed by Roy and Katie Parsons in 1994. The Parsons were inspired by the game Pai Gaw, a chinese domino game. Dominoes are used to play games like All Fives, Mexican Train, Fortress, and Texas 42, just to name a few. They can also be used to create an awesome toppling effect. So, whether you are using it for educational purposes or as a pub game, this set is sure to be everyone’s favorite! * ALL ABOARD: 91 double twelve ivory colored heavy-duty plastic dominoes with assorted color dots in a black and red vinyl case with snap closure.
