Passover Haggadah Step #4:

Passover Haggadah Step #4: Yachatz ("to divide" in Hebrew): The middle matzah of three matzahs which are placed on the Passover Seder table is broke into a larger half and a smaller half. The largest piece, called the afikomen, is wrapped in a napkin, hidden and returning the smaller piece to the stack. During the seder, the children try to find the afikomen. The Seder can only end after the afikomen is eaten. Hiding the afikoman is a kind of game introduced to keep the children at the seder awake throughout the evening. Afikoman means "dessert" in Aramaic. Some interpret the 3 matzah as a reminder of the three Patriarchs: Abraham, Isaac, and Jacob. The middle matzah, the one broken, symbolizes the Passover Lamb, would correspond to Isaac who was taken to Mt. Moriah what would become the Temple Mount to be offered as a sacrifice! (See Genesis 18:13-14, 21:1-2, 22:1-18 and 2 Chron. 3:1.). Afikomen has to be consumed before midnight, just as the lamb of Pesach was eaten before midnight during the days of the Temple in Jerusalem
