Welcome tequila_j,
They're pretty hard to come by this year for some reason.
The latested email from Cundco, sent 3 minutes ago mentioned:
(English: Greetings from an old friend, Santa. This year, he still has enough poems to read, so a simple question will do it, to get the "Spiel15" tile. Please read more about how to, in the products specification.)
I wonder if this was a mistake - as the Spiel15 tile is not available.
