A device for shuffling playing cards is described as having a substantially rectangular enclosure with a width that is greater than the length of the playing cards to be shuffled and a height that is less than the width of the playing cards to prevent any of the cards from turning upside down. The length of the enclosure is greater than three times the length of the playing cards to provide room for cutting the cards. Two smaller partitions are placed inside the enclosure at opposite sides to impede the side to side motion of some of the playing cards when the card shuffler is shaken from side to side. The cards whose motion has been impeded settle into various random planar alignments relative to other cards, similar to a "cutting" of the cards. Repeated shaking of the card shuffler intermingles the cards and achieves an effective shuffling action.
