Do wonder if every puzzle has been lifted from the US version.

If they are, they need to check them properly, make sure there's no Americanisms, like terminology not used in British English, and spelling differences. For example, if a puzzle said "MAGGIE'S PACIFIER", that wouldn't be suitable, because we call those dummies. Likewise if a puzzle said "SENSE OF HUMOR", that'd be correct in the US, but wrong here because we spell colour with a U.

I don't suppose there's a WOF equivalent to Jeopardy!'s fansite J!Archive?
