green group · The short answer
KINDS OF MATS
Each puzzle word passes the same exact test. The four mappings show how the answer works.
A prayer mat is a surface used for kneeling, prostration or other bodily postures during religious prayer.
A welcome mat is placed near an entrance, often to wipe footwear and greet people arriving at a home or building.
A wrestling mat is the padded surface on which wrestlers train or compete while reducing impact against the floor.
A yoga mat provides a defined, cushioned and relatively nonslip surface for poses and floor exercises.
Why this group was difficult
- The entries initially suggest unrelated activities
PRAYER, WRESTLING and YOGA name activities, while WELCOME reads as a greeting, so their shared physical object is not immediately visible. - The linking noun is absent from the board
Solvers must supply “mat” themselves and then recognize that every resulting phrase names an actual kind rather than a loose association.
How to spot this pattern next time
When three nouns seem like unrelated activities, try attaching the same everyday object to each and check whether the fourth entry produces an equally standard phrase.
Use the least activity-like word as a test case: WELCOME strongly suggests MAT, which can then be checked against PRAYER, WRESTLING and YOGA.
Four useful facts behind the group
- All four mappings are formed by placing the board word directly before “mat.”
- A welcome mat is associated with an entrance rather than a sport or exercise.
- Wrestling mats are padded to create a suitable surface for grappling and falls.
- Yoga mats provide personal floor space and traction for poses and exercises.
Questions players ask
The details people search after seeing the group
What connects PRAYER, WELCOME, WRESTLING and YOGA?
Each combines with MAT to name a kind of mat: prayer mat, welcome mat, wrestling mat and yoga mat.
Why is WELCOME included with three activities?
WELCOME does not need to name an activity; WELCOME MAT is itself an established type of mat commonly placed by an entrance.
What was the key to solving the kinds-of-mats group?
The key was supplying the missing noun MAT and confirming that all four resulting combinations name recognizable objects.
