You need three players, 32 cards and a thick skin. After all, for many Germans, skat is quite a serious business. People have played the card game skat for more than 200 years in Germany. Its origins date back to between 1810 and 1820 in Altenburg, in the eastern German state of Thuringia. Since then, it's been a game staple in pubs across the country. An estimated 20 million people play today.
