I thought this game was Blind Man's Bluff, but that is a linguistic slip. Buff means to gently push or tag. This game is like tag but IT is blindfolded.
Versions:

• Player taged becomes it
• Player tagged is out, continue until everyone is out
• Player tagged must be identified by IT by feeling their face. If IT is correct the tagged person is IT
• IT stands inside circle of players holding hands
