If you want to fill a particular gap in Arthur’s Museum, start with the missing artifact. Its detail view tells you which mineral to collect. That makes the museum a useful starting point when you have several mines to choose from and only a few minutes to play.
Work from the empty slot back to the mine
- Open Museum. The count at the top shows how many different artifacts you have discovered. Browse the rarity sections and open an undiscovered item.
- Read the mineral in its hint. Look for a mine producing that mineral in any region you can reach. The rarity heading groups the display. The mineral in the hint determines which collection can advance this search.
- Collect from the matching mine as you play. More than one undiscovered artifact can belong to the same mineral, so the next discovery may fill a different slot. Return to the museum to see which one appeared.
What happens when you find one?
The game credits the first-discovery token reward when the artifact is found. Open the discovered item to read its story and see the reward labeled Reward earned. Opening it also clears its new-find marker. You can revisit the story later without spending tokens or earning a second copy of the reward.
For example, suppose two empty slots show the same mineral hint and you prefer the second artifact. Collecting that mineral is a useful choice for either slot. If you discover the first one, your collection has grown and the second remains eligible. Reopening the first artifact’s story will show its earned reward. To continue toward the second, go back to collecting the indicated mineral.
