One Year of Chocolate!

I have just received this email ad from the French supermarket chain Casino.  For some reason yet unknown to me, the French seem to promote chocolates for Easter (Pâques) -- perhaps to help them get through the Lenten season.

The other thing that got my attention is the promo game that says "1 an de chocolat à gagner!"  One year's worth of cholocate to win!  Hmm... I wonder what kind of game it is.
