In Raiatea, players act as members of the Arioi, a secret Polynesian religious society. Over the course of the game, the Arioi will build colossal Too statues in attempt to win the favor of their god, Oro. In the games action rounds, players take turns leading the group to various action locations. In ceremony rounds, players call upon the gods for help in building the massive Too. Construction may fail without these gods help, so players must plan their rituals carefully and know how much mana to sacrifice in order to accomplish their goals. At the end of the game, the player who has collected the most victory points will guide the group as their new High Priest!
