Keywords Markov Processes
We analyze the infamous card trick known as the ``Kruskal Count'' and find that it is a Markov Process. We derive the $m$ by $m$ transition matrix for this process in the general case of a deck of cards with $m$ face values. In particular, we derive the exponentially decaying probability of the correct guess after $n$ cards have been dealt for the deck with $10$ face values.
