En The Believer 37, hay un fantástico artículo de Perec sobre los crucigramas. Él mismo se dedicó a crearlos durante años. La última parte del mismo es todo un reto:

5. Of An Unsolvable Crossword

…In practice, I do not think there are unsolvable crosswords, but only crosswords whose solution is made more difficult by the choice of little-known words. Thought I myself prefer crosswords made of simple words, whose difficulty comes from confusing definitions, I offer you, to get done with this brief introduction, a crossword whose -let’s face it- commonplace definitions hide a certain number of rather rare words:

I. You are here.- II. A dieter’s likehood of success.- III. Splat.-Core of core.- IV. Rose to face.- V. He can lead a harmonic.- Its act is intimidating.- VI. Change the handle of.- Method.- VII. Not quite ten.- Coiffiture.- Managed.- VIII. She had a nice bust.- IX. Egg salad ingredients.-Salt.

1. Brood.- 2. Vestibules.- 3. Common type.- 4. Staff conections.- 5. Gets punched out because of politics.- Merrier?- 6. Removal, even if it were electronic.- Tabletop.- 7. The far side of the moon.- It is related to the circunference.- It is the circunference .- 8. Blind Spots.- 9. Constrictor.

Llevo un rato y no he sacado nada en claro. A ver quién es el valiente.
