Domino is a small, thumb-sized rectangular block that may be blank or bearing from one to six pips (or dots): 28 such dominoes form a complete set. It is used in many games played by matching the ends of dominoes and laying them down in lines and angular patterns.
Make a domino fall several times and observe its effect. It acts much like a firing neuron in your body.
There are many different ways to play domino. However, most games fall into one of four categories: bidding or auction games, blocking and scoring games, and rounds games. The winner of a hand is awarded points equal to the total number of pips on his opponents’ remaining tiles in their hands.
