The game chinchon came up in another thread, which made me think - hey, we need to start something on Spanish card games!
Spain has a unique deck of cards. Instead of hearts, spades, etc., they have gold coins, wooden clubs, swords, and "copas" (they look something like trophy cups). A deck of Spanish cards might make a good gift for someone who likes playing/learning new card games.
In our house we play chinchon and escoba, but my favorite game is MUS!
Mus is played with four people. It involves strategy, cooperation, lying, twitching of facial muscles on the sly (which MUST be honest - you have to be careful about when you lie), and it's a lot of fun. Many people find it too hard to play, but once you get the hang of it, it can be addictive.
A foreigner who learns how to jugar al mus becomes something of a celebrity, and his/her respect rating goes sky high. You can find people tucked away in a corner of a bar playing mus, or in organized tournaments in almost every town.
If I've captured your attention, and you'd like to learn more, there are websites out there (here's one - in Spanish, of course!

Have fun!
