===Shuffling===
{{main|Shuffling}}
Shuffling is the process of bringing the cards of a pack into a random order. There are a large number of techniques with various advantages and disadvantages. ''Riffle shuffling'' is a method in which the deck is divided into two roughly equal-sized halves that are bent and then released, so that the cards interlace.<ref>{{Cite web|title=Why Do Math?|url=https://www.whydomath.org/Reading_Room_Material/ian_stewart/shuffle/shuffle.html|access-date=2020-10-12|website=www.whydomath.org|archive-date=December 27, 2019|archive-url=https://web.archive.org/web/20191227235253/http://www.whydomath.org/Reading_Room_Material/ian_stewart/shuffle/shuffle.html|url-status=live}}</ref> Repeating this process several times randomizes the deck well, but the method is harder to learn than some others and may damage the cards. The ''overhand shuffle'' and the ''Hindu shuffle'' are two techniques that work by taking batches of cards from the top of the deck and reassembling them in the opposite order. They are easier to learn but must be repeated more to sufficiently randomize the deck. A method suitable for small children consists in spreading the cards on a large surface and moving them around before picking up the deck again. This is also the most common method for shuffling tiles such as dominoes.

For casino games that are played for large sums it is vital that the cards be properly randomized, but for many games this is less critical, and in fact player experience can suffer when the cards are shuffled too well. The official [[skat (card game)|skat]] rules stipulate that the cards are ''shuffled well'', but according to a decision of the German skat court, a one-handed player should ask another player to do the shuffling, rather than use a [[shuffling machine]], as it would shuffle the cards ''too'' well. French [[belote]] rules go so far as to prescribe that the deck never be shuffled between hands.
