Oh Fortuna invites players to challenge their luck against the gods as they roll dice to try to claim cards from the heights of the heavens or the depths of the seas. In game terms, players have a deck of cards numbered 0-42, and players need to roll these numbers on dice to claim particular cards. Only the ten highest and ten lowest cards are worth points, with the other cards giving you the ability to manipulate die results, so you need to collect these cards first, then use them to push toward the depths or heights to grab the cards that matter in the end.
