When I was about ten, a meddlesome adult told me that "blindman's bluff" should be
"blindman's buff.
The wordbook I am reading says "bluff" in seventeenth century mant "blindfod", and
that blinkers on horses were called "bluffs"
On the Internet, the two spellings are used to mean the same thing.
Have any of you got a theory to explain how "blindman's buff came into use?
Outside of just ignorance?
