Question 1102282
.
Let me tell you one story, which I read somewhere many years ago . . . (just do not remember where).


<pre>
    It was during World War I. 

    German army was in a broad offensive.

    French army was retreated. 

    Then the French aviation scattered fly-sheets with similar puzzles over the German army.

    The German soldiers started collecting these fly-sheets; stopped their attack; and started solving the puzzles.

    The German attack was stopped, in this way.

As a conclusion, I want to say that your puzzle suits very well for such a purpose !


(and doesn't suit for anything else).
