Thanks.  Yes, I've gotten the "house numbers" (4 digits) - many times.
They're very legible, but still don't work (TB 4.5.1 / 4.5.2 - Windows).
When I enter them, Cloudfare doesn't give any message, just a new 
captcha image.

Sometimes, it shows another 4 digits - still clear.  Then another & another.
After a few times, it may switch to the letters on an acid trip.
Even when I can read all the letters, it still doesn't take.
After the 1st attempt or 2, it also may change the instructions to a non 
English language.  I assume based on exit relay location.

In Firefox, I can usually get similar looking captchas to work - 
especially if it's not from Cloudfare.

Which "out of the box browser" do you mean?  I've tried clean installs 
of TB before w/ default settings.
Don't remember having any better luck w/ Cloudfare.

To get it to work, are you allowing 1st and / or 3rd party cookies - for 
both the target site & whatever the URL is for the Cloudfare captcha page?
I wonder if the OS makes a difference to Cloudfare?

I think it may be (or used to be so).
IIRC, in Firefox, if NoScript wasn't set to allow all scripts (possibly 
1st & 3rd party), sometimes I couldn't see all elements on the captcha page.
