The Card Shuffler is designed for use with one or two packs of standard playing cards (not supplied) and is ideal for general card playing including bridge or casino games such as poker, as well as being a great product for those with limited use of their hands due to arthritis or other conditions. The portable Automatic Card Shuffler is battery powered (4x AA batteries - not supplied), so requires no power lead or socket. Operation is by a simple push button to stop/start the shuffling motor.
