"A caller (who can be switched at will) guides one blindfolded member at a time down a field to smash one of five hanging skulls with a war club they’re holding, grab the tiles that fall out, take them to the solving station, and run back. Once all five sets of tiles are on the station, the entire tribe runs down the field to it and arranges them to form a two-word phrase (Cannibal Isles)." ~ @SurvivorWiki
