Look at the original thread - there was a bit of discussion:

but to run the code you posted, right click on a sheet tab and select view
code. Paste the code in the resulting module. Clean up any errors due to
word wrap. Now go to the worksheet and right click in the Range("A1:C3) -
the code should run and place an X or O for each right click in that range
until a winner has been determined - look down at the status bar. Not a
whole lot of visual feedback.
