This board becomes clear pretty quickly once you stop reading the clues as materials and start reading them as rock names.
Marble and Obsidian can feel a little broad at first because both words also show up in design or sculpture, but Sandstone pushes the board back toward geology.
From there, the rest settle fast: marble rock, obsidian rock, slate rock, granite rock, and sandstone rock all point to the same category.
The answer was "Types of rocks".
Once that answer is in place, the whole board reads like a straightforward list instead of a loose theme.
Types of rocks
| Clue Word | Example Phrase | Connection Explained |
|---|---|---|
| Marble | "Marble rock" | "Marble rock" is a familiar geological reading, even if the word also appears in design and sculpture. |
| Obsidian | "Obsidian rock" | "Obsidian rock" fits once the board is read through geology instead of decor or jewelry. |
| Slate | "Slate rock" | "Slate rock" is a direct rock reading, which keeps the set grounded in the same category. |
| Granite | "Granite rock" | "Granite rock" is another familiar geological fit that reinforces the answer cleanly. |
| Sandstone | "Sandstone rock" | "Sandstone rock" is the clearest anchor in the set because it points straight to a rock category. |
Wait for the clue that narrows the category
When a few clues can also read as materials or finishes, look for the word that sounds most natural as part of a rock list.
Prefer exact fits over loose associations
Marble and Obsidian can pull you toward design or decor first, but the stronger answer is the one that explains the full set directly.
Re-check the earlier clues once the frame tightens
After "Sandstone" points you toward geology, go back and make sure Marble, Obsidian, Slate, and Granite still hold under the same answer.
The answer is "Types of rocks". Each clue works as the name of a rock, and "Sandstone" makes that reading especially easy to verify.
The connection is rock names. The board looks a little broader at first because Marble and Obsidian also appear in non-geology contexts, but the full set settles once every clue is read as a rock.
"Sandstone" is the strongest anchor because it points most directly to geology and makes the category easier to test across the whole board.
