Are you familiar with the Buffon Needle experiment? It’s one of the first examples of Monte Carlo simulation to approximate pi. That’s the theme of this puzzle.

BUFFON + NEEDLE = PIPIPI This one can be tough, but it is doable by handle given the numerous constraints to get P and I and that all ten digits are used.
