iPhone iPhone 5/iOS 6 Passbook apps

My iPhone 5 has shown the same 5 or so Passbook apps since the day I bought it when I tap on "Apps for Passbook" in the Passbook app. Is this an exhaustive list or are there apps that aren't listed in the Passbook app?

Thanks

There are dozens. Just search for passbook in the store or at appshopper.

The first ten results are: -

Draw Something Free
SongPop Free
Groupon
Draw Something
Torch
Facebook
Words With Friends Free
Logos Quiz Game
Lemon Wallet
Scramble With Friends Free

Out of all of those, only Lemon Wallet is a Passbook-enabled app, so the search feature is pretty much useless for me.

Thanks though!

Use the search feature here for existing PassBook threads

Most of those are US only it looks like, and I can't seem to find much for the UK. I did a search for "Passbook UK," "Passbook UK Apps" and "Passbook UK 2013" but I can't find much of anything.

Thanks
