The research teams are outfitted and ready to embark on their adventures to find five forgotten cities. Who will lead the way to fantastic discoveries?

Each player guides a team of explorers on up to five expeditions. To advance along an expedition path, a card in the pathâ_x0080__x0099_s color must be played for each step forward. The card must be of equal or greater value to the playerâ_x0080__x0099_s card previously played on that path.

After playing or discarding a card, the player draws a new card. Skilled team leaders assess when to play, hold, or discard their cards to move their own teams forward while at the same time preventing their opponents' teams from getting ahead.
