To set up, place a central board representing the island on the table, and give each player a personal map they will use to transcribe their discoveries. Each turn, players choose two actions among these:
- Move their explorer pawn on the central board.
- Discover new terrains close to your explorer pawn, choosing from four randomly drawn tiles.
- Claim control of areas.
A type of terrain on the central island must be explored twice before being validated. Thus, the unvalidated terrain types can change — "You thought you saw grass? You were mistaken." — and then your personal map will no longer match the central board.
You have to find the ideal balance between your personal objectives, and a correct cartography of the island.
