What is a chickenfoot?
Chickenfoot is a version of dominos that creates a chickenfoot when a player plays a double.
Any time a player plays a double of any number on the exposed domino with the same number as the double, the player calls "Chickie (Number)".
When the players answer the double with three matching dominoes, the shape of the dominos resembles a chickenfoot.
The interactive hubs have a chicken sound and a train whistle. You push the hub for the chicken sound when a double is played to alert the players that they must answer a double.
