Domino games divide into two families of games: block games and scoring games. The aim of block games is to block the opponent so he can't play any of the tiles in his hand. The goal of scoring games is to score as many points as possible throughout the game.
Dominoes is a Chinese game. Italian missionaries might have brought it to Europe in the early 18th century, and the game quickly spread through Europe.
