A card shuffler, also known as a card shuffler machine, is a device used to randomize a deck of playing cards. Card shufflers are often used in casinos and other gambling establishments, as well as in homes and other settings where card games are played. There are many different types of card shufflers available, each with its own advantages and disadvantages.
Card shufflers can be either manual or automatic. Manual card shufflers require the user to physically shuffle the cards, while automatic card shufflers do the shuffling automatically. Automatic card shufflers are often more expensive than manual card shufflers, but they can be more convenient and faster. Some card shufflers also have features such as the ability to shuffle multiple decks of cards at once or to deal cards directly to players.
