Marked Playing Cards Dealing Machine
shuffling machine is a machine for randomly shuffling packs of marked playing cards.
Because standard shuffling techniques are seen as weak, and in order to avoid inside jobs where employees collaborate with gamblers by performing inadequate shuffles, many casinos employ automatic poker shuffling machines to shuffle the marked playing cards before dealing. These machines are also used to reduce repetitive motion stress injuries to a dealer.
Shuffling machines have to be carefully designed, as they can generate biased shuffles otherwise: the most recent shuffling machines are computer-controlled. The randomness or otherwise of cards produced from automatic shuffling machines is the subject of considerable interest to both gamblers and casinos.
Shuffling machines come in two main varieties: continuous shufflers, which shuffle one or more packs continuously, and batch shufflers, which shuffle an entire single pack in a single operation. Batch shufflers are more expensive, but can avoid the problems associated with some continuous shufflers, whereby the shuffling operation only slowly changes the state of the deck, and new cards may be taken before shuffling has sufficiently randomized the pack, allowing some players to shuffle trackcards through the shuffling process.
