A commonly used shuffling process in which two halves of a deck are intermixed by the dealer.

A commonly used shuffling process. To accomplish a riffle, the deck is divided roughly in half and the two halves are interleaved by pulling the card corners up with the thumbs and letting the two halves 'riffle' together. Riffling is also sometimes called 'zipping' the cards. Like card Stripping (see below), the riffling process can span a range from a fine riffle to a coarse riffle.
