I think everyone knows what domino is. Often we treat dominoes as blocks for children, a simple toy used to learning to count. Sometimes we play with kids because this game seems simple. In my country (Poland) it’s rather unusual to see adults playing dominoes. What a pity! This game is more addictive than you think, and besides, it has a fascinating history. You can play many games with one set of domino tiles, just like you can play many games with one deck of cards.
