Combinatoric Solitaire
Knuth mentions an anecdote about runs/sequences of increasing integers - there was a mathematician/scientist who would play a form of solitaire in which he would place cards on an existing pile as their face value increased, and start a new pile as their face values decreased. The question is, how many piles will result, and playing this form of solitaire is a form of "empirical" sampling.
