Blind Man's Bluff or Blind Man's Buff?

There was a lot of confusion about whether we call our film Blind Man's Bluff or Blind Man's Buff. Jake was intent on the latter, but some people were confused as to why the Blind Man was physically attractive. One of the posters we looked at and incidentally had in our film was a cartoon produced in the 1800s, named 'Blind Man's Buff'

As you can see, the writing on the cartoon clearly says Blind Man's Buff. Surely this was hard-boiled evidence that our film should be named Blind Man's Buff. But for me, it wasn't enough. I decided to research this the best way I could, by searching up Blind Man's Buff on google. This lead me to a wikipedia page on Blind Man's Buff.

The article initially suggested to me that it can be Buff AND Bluff. However, as I read on, I discovered that the game of Blind Man's Buff was later to be known as Blind Man's Bluff, due to linguistic corruption.

This lead me to believe that due to the wording of buff in modern day slang is now known to mean physically attractive, this corrupted and changed the wording from Buff to Bluff. Therefore, we decided, to make modern audiences understand the lexis, we have now named the film Blind Man'sBluff. However, due to the alternating between buff and bluff, some of our posts may name the film Blind Man's Buff. This was when we thought the film to be called Blind Man's Buff. It is now, for definite, Blind Man's Bluff. Thank you for reading this post.
