Eid refers to the Muslim festival, Eid al-Adha which honors the willingness of Ibrahim (Abraham) to sacrifice his son as an act of obedience to God's command. But, before Abraham could sacrifice his son, God provided a lamb to sacrifice instead. Eid al-Adha is a Festival of the Sacrifice and families celebrate with prayers, charity, social gatherings, and Festive Meals!
In Eid, players will be going to the market to try to get all the ingredients they need to complete the recipes before the other player does. Players will gain ingredients by altering the current market for ingredients and then trading away their current ingredients to get more of another.
Players will alter the market by playing a card to a two-sided function. The player will then use that function to trade in one type of ingredient to gain the ingredients listed on the other side of the function. Play will continue until one player has completed two of the three recipe cards.
