green group · The short answer
THINGS WITH WHEELS
Each puzzle word passes the same exact test. The four mappings show how the answer works.
An OFFICE CHAIR commonly has several small wheels or casters attached beneath its base.
A ROLLER BAG has built-in wheels so it can be pulled rather than carried continuously.
A SHOPPING CART uses wheels so shoppers can push merchandise around a store.
A STROLLER has wheels that allow an adult to push a seated or reclining child.
Why this group was difficult
- The objects serve unrelated purposes
Seating, luggage, shopping and child transport do not initially suggest a single functional category. - The physical rule is intentionally broad
Searching for an exact use can obscure the simpler observation that every object ordinarily has wheels. - ROLLER BAG attracts a luggage pairing
ROLLER BAG can draw attention toward CARRY ON, even though the board uses CARRY ON as a verbal expression.
How to spot this pattern next time
When several concrete nouns remain, compare visible physical features before searching for a shared setting or specialized purpose.
Use SHOPPING CART and STROLLER as anchors, then test which other objects characteristically roll on their own wheels.
Four useful facts behind the group
- Every entry names a tangible object rather than an action or abstract idea.
- The wheels range from small chair casters to larger transport wheels.
- The objects can be pushed, pulled or repositioned while rolling.
- The official rule requires no shared destination, user or setting.
Questions players ask
The details people search after seeing the group
What connects OFFICE CHAIR, ROLLER BAG, SHOPPING CART and STROLLER?
They are all THINGS WITH WHEELS, despite having different everyday functions.
Why is OFFICE CHAIR included with the rolling objects?
A typical OFFICE CHAIR rests on a wheeled base with casters for easy repositioning.
Why was the green group potentially misleading?
The objects seem functionally unrelated, and ROLLER BAG also tempts a false luggage connection.
How can I spot this physical-feature pattern again?
Compare concrete objects for shared components such as wheels, handles, lids or hinges before imposing a setting.
