What has many rings but no fingers?

How to think about it

1. Rings without fingers must be ring shapes rather than finger rings.
2. Saturn has rings, a circus has rings, and a cut log shows rings.
3. The hint says you count them to learn its age. Only one of those has rings that record years.
4. A tree adds one growth ring each year, and no tree has fingers.

Why “a tree” is the answer

When a tree trunk is cut, you can see concentric rings, one added each growing season. Foresters count them to find the tree’s age, which is exactly what the hint describes. The riddle uses the jewelry sense of “ring” to hide a meaning from biology.

Common wrong answers

• Saturn. Saturn has rings and no fingers, so it is a clever guess; the age hint points to a tree instead.
• A telephone. A phone rings many times, but it does not have rings.
