Small World is a zany, light-hearted civilization game in which players vie for conquest and control of a board that is simply too small to accommodate them all. Picking the right combination of fantasy races and unique special powers, players must rush to expand their empires -- often at the expense of weaker neighbors. Yet they must also know when to push their own over-extended civilization into decline and ride a new one to victory.Small World Underground brings the action underground for a new battle over more land to take over! Designed by original Small World author, Philippe Keyaerts, this standalone expansion features all new Races and Special Powers, and introduces Monster occupied regions that protect Relics and Places of great power!Small World Underground is recommended for 2-5 players ages 8 and up, and takes approximately 60 minutes to play. It can be played on its own or with other Small World game elements.
