Taking a standard deck and four players, deal everyone 18 cards. Starting with the person to the dealers right, cards are played in tricks. The winner of each trick begins the next round. You must follow suit if possible, high card takes the trick, trumps beat suit cards, high trump wins if more than one gets played. You can start with a trump.
Numerous variations exist, including games that involve bidding, etc.
No-one knows the 'true' origin of the Tarot. The most common myth is that it was brought to Europe by the Gypsies - but this myth come from the fact that very early occultists who used the Tarot fancied that it came from Egypt. They were as wrong about that as they were about the homeland of the Gypsies. It is most closely related to the 'Mamluk' deck of the Islamic world, which had suits cups, coins, swords, and polo-sticks. The Tarot was originally used for a game called 'tarocchi' in Italy, which is sort of a distant cousin to Bridge.
