Tigris and Euphrates is a German-style strategy board game designed by Reiner Knizia and first published in 1997 by Hans im Glck. The game is set as a clash between neighboring dynasties at the dawn of civilization. The game is named after the rivers Tigris and Euphrates in the region now called the Middle-East. The rivers together formed natural borders for an area which harboured several grand ancient civilizations, including Sumer, Babylonia, and Assyria. The Greeks called this area Mesopotamia, which literally means 'between the rivers'. The game can be played by 2, 3 or 4 people. The play offers both tactical and strategic objectives.
