That's because it's a USA dialect quiz, Tony. I doubt it recognizes north Wales (if that is indeed your accent).
It did correctly put me in the mid-Atlantic (Maryland, Virginia, and Delaware), though with more heat in Virginia, probably because I selected 'brew-thru' for a drive-through liquor store, only because I have encountered ONE of these in my entire life, nowhere near where I grew up, probably shifting me south. If I had never encountered this isolated business, I would have selected 'I have no word for this kind of thing'. I am 'Merlin' born and bred, and my accent is thicker now that I've lived on the Eastern Shore for 25 years than it was in high school.
