A love A&G sets, and always read about people trying to break the code. I never understood how is this done.
But I always kept the few cards I got about it, like these two 2011 A&G cards promoting the code game.
And maybe that's why I never looked closely to the cards, for I always thought it was just a promo card. But then I looked better and noticed that the clock is not marking the same time in both.
And after checking the wonderful internet I found:
"The first thing needed were the promo cards because the clocks reflected in the mirror were important. The promo cards had 10 different times on them."
Ohhhhhhhhhhh So that's it! Everything is explained here.
That's why it pays off to not throw any card, even the promo ones, out.
