NUMB3RS - Season 2 - "Double Down" - Perfect Out-Shuffles

Activity Overview

In "Double Down," card auto-shufflers in casinos are discussed. These devices can be used with more than one deck of cards, and offer casinos a method for randomizing the cards that are dealt, while minimizing any opportunity for the person dealing the cards to cheat. However, there are ways to manually deal cards in a predetermined manner.
