Necro alert ... I realize my post is almost three years too late, but this was the most "general" BB5 thread I could find as a place to tether a link to my new discussion.
Yes, 12 tiles were different between the Wheel of Fortune base game and the Carcassonne base game.
Actually it's just 9 or 10 (depending on whether you count the start tile's back changing from dark to light).
Specifically, the three "bonus" WoF tiles in BB5 are the RRFF, RFRF, and the RFRC. Just the fact that they added more than necessary was what confused me.
Yeah, this was also part of the confusion for me, too.
Though I still don't quite have a Wheel of Fortune secured for myself, I have been trying to wrap my head around these configuration differences, both obvious and subtle. It's been frustrating.
I've read a lot of information in these forums, in the CAR, on BGG and the interwebs in general, and even a few posts on CarcF. Almost everyone has something helpful to add, but nobody (that I have found, anyway) has really laid out the full picture; I haven't found any one source that is complete and 100% correct, at least not in a way that I could understand. The CAR does offer a fair amount of information, but it could use more clarity in the details, additional tile distribution images, and a correction or two.
So yesterday I went through the mind-numbing exercise of downloading tile scans of both standalone and BB5, and doing a tile-by-tile comparison of every detail including gameplay, watermarks, and even the decorative buildings. Then I created some graphics to illustrate what I learned, with the intention of using them in the next CAR update. You can see it all in the
CAR 7.5 Prep Discussion: Wheel of Fortune Version Comparison thread.
Here's a quick preview of one of the images, which for now is only thumbnail quality until I have my own copies that I can scan at better resolution.
