ZOdiac is a solitaire card game which is played with two decks of playing cards shuffled together. AN old game, it first appeared in Lady Adelaide Cadogan''s book Illustrated Games of Patience. IT is so-named probably because of its "globe"-shaped layout. IT had many variations until its rules were standardized in 1914. FIrst, eight cards are deal in a row. THey form the cells which make up the reserve, or the "Equator". EAch reserve cell can only hold one card. THen twenty four cards are dealt in a circle surrounding the Equator to form the tableau, or the "Zodiac." The game is divided into two phases: the first phases consists of playing the rest of the cards into the Zodiac and the Equator; the second phase is the building of the cards into the foundations.
