A card is dealt from the deck, and any player that has the picture of that card on their board puts a bean on it. The pattern to win (a column or a row) is determined at the beginning of each round. Once one player makes that pattern, they shout Loteria" (hit the Loteria  button on Google's version) and win the game.

Be the first person to call out Lotera!  or Buena!  in order to win the game. For more playing options, you can choose to fill in a different pattern at the start of a new game (line, diagonal, vertical or horizontal, full card, the four corners or the 4 in the center).
