blue group · The short answer
THINGS THAT BLINK
Each puzzle word passes the same exact test. The four mappings show how the answer works.
A text-entry CURSOR can repeatedly appear and disappear to mark the position where the next character will be entered.
EYELIDS rapidly close over and uncover the eyes during the ordinary physical action called blinking.
A SMOKE DETECTOR can use an intermittent status light to indicate power, normal operation or another device state.
A TURN SIGNAL repeatedly illuminates and goes dark to show that a driver intends to turn or change direction.
Why this group was difficult
- The relevant link is an action, not a type
The four entries belong to unrelated domains, so sorting them by object class or location does not expose the shared behavior. - Blinking happens for different reasons
EYELIDS blink biologically, while a CURSOR, SMOKE DETECTOR and TURN SIGNAL use intermittent visual indications. - SMOKE DETECTOR may suggest sound first
Its loud alarm is more salient than its small status light, making its visual behavior easier to overlook.
How to spot this pattern next time
Convert concrete nouns into observations by asking what each item visibly does. That shift reveals a repeated on-off or open-close action.
Treat CURSOR as an anchor and look beyond screens: the same visual rhythm can occur in anatomy, safety equipment and vehicle lighting.
Four useful facts behind the group
- A text cursor can be displayed as a vertical marker that periodically appears and disappears.
- EYELIDS are movable folds of skin and muscle that can close over and uncover the eyes.
- Many smoke detectors have status lights that illuminate intermittently to communicate operating information.
- A TURN SIGNAL uses a repeating flash to make a driver’s intended direction visible to others.
Questions players ask
The details people search after seeing the group
What connects CURSOR, EYELIDS, SMOKE DETECTOR and TURN SIGNAL?
They are all THINGS THAT BLINK, although the blinking ranges from a bodily movement to electronically controlled flashing.
How does a SMOKE DETECTOR blink?
A SMOKE DETECTOR may have a small status indicator that flashes intermittently to communicate power or operating state.
Why does CURSOR belong in the blue group?
A text-entry CURSOR is often shown as a marker that repeatedly appears and disappears at the active position.
Does blink have the same meaning for every answer?
The visible pattern is shared, but EYELIDS physically close and open while the other entries show intermittent light or display states.
