Dominoes with nine spots
A normal set of dominoes has 28 tiles and the largest is "double six." This special domino set has more tiles and the largest is "double nine." How many tiles does it have?
You can buy domino sets going up to "double twelve." How many tiles would these sets have?
A normal set of dominoes can be matched up to make a continuous chain that uses all the tiles. Why is this impossible with the set in the photograph?
