Let your eyes leave the grid.
A letter search is a good place to notice when looking harder is no longer helping.
Change direction before adding effort
After scanning several rows, try a column or a diagonal. A different view can be more pleasant than repeatedly reading the same line.
Use a found word as a stopping point
There is no time limit or daily set to finish. Finding one fruit can be enough for a short visit. The list has no financial value or account status attached.
Take a visual break
Look away from the letters between searches and adjust zoom to a comfortable size. A fresh page resets the puzzle, so do not expect a stored progress history when returning later.
Describe selection issues clearly
For support, name the word and the two endpoints you tried. A browser and device description is useful; unrelated identity or financial information is not.
A clear way back
Read the controls before returning, or leave the activity for another time.
