Spoiler ~~
it took me 19 mins 14 secs to finish this, and i was the first (unless someone else finished it while i was doing the puzzle) but i figured that i might as well right it out for others so here it is:
QU'ILS
MANGE-
NT DE LA
BRIOCHE

Spoiler over
Good luck xx.

Dommage, je ne crois pas qu'il soit faisable sans hypothèse/intuition, sans compter les solutions multiples...

Thanks Hjaw123, I don't think I would have finished it..
It's only intuition, 'cause there are many solutions >.<.

"Quils" was really tricky - I cannot speak French and thought it was "Quile"...

My French is poor-It took me 26 mins without cheating-I was stuck on the Q. I thought gateaux was French for cake:)

Thank you, Hjaw123! Too much guessing without your help.

Thanks Hjaw123 - don't think this puzzle is logical - I don't know how you guessed it within 20 minutes - took me longer and that was with your help!
