A word is displayed…
Underneath it are four choices of words…
You click on the one you think best defines the first word…
If you get it right, you get a harder word. If wrong, you get an easier word…

Finally, you get smarter and enhance your vocabulary while doing a noble thing helping poor and hungry people get food…
A very interesting approach and praiseworthy effort…
