WebMay 6, 2024 · Shuffling. Shuffling is a procedure used to randomize a deck of playing cards to provide an element of chance in card games. Shuffling is often followed by a cut, to help ensure that the shuffler has not manipulated the outcome.[citation needed] One of the easiest shuffles to accomplish after a little practice is the overhand shuffle. WebMay 25, 2016 · The modern method of the Fisher-Yates algorithm is a slightly-modified version of the original. The steps look something like this: GIVEN: A collection of items which we want to randomly sort. FIRST: Randomly select one of the "unshuffled" items. THEN: Swap the selected item with the last item in the collection that has not been selected.
