Finally a networked multiplayer game in the vein of the puzzle classic Bust a Move/Puzzle Bobble! Beat your friends in this addictive game, or play against a random opponent! Remember to sign up to participate in the score system.
Its available on GNU/Linux MacOS X and windows. I played a few games online, at the end of each round you get to chat with your opponent. All the people I met were Spanish though they all spoke English as well. I learned some Spanish from this Wikibook and a friend who is studying Spanish at Uni so hola, como estas ? La estudiante es tan inteligente como el profesor. If you let your kids play this game maybe think about introducing the Spanish book.
