This would require VBA or an add-in, so I guess the answer is "no, there
is not a simple way." However, Tushar's add-in is very simple to use if
it does what you want. It doesn't sort the slides but plays them in
random order. Check out more information at "Randomize the order of a
PowerPoint presentation" from the PPT FAQ:
