You may have seen it happen before, but you may not have known there’s a name for it!
Casino card game dealers have a very specific procedure they follow related to shuffling the cards. To begin the shuffling process, cards are spread out on the table and moved around randomly.
This step in the shuffling process is called “washing” the cards. It’s also known as “scrambling.”
Once the cards are “washed,” they’re squared up and are then “riffle shuffled,” often multiple times, before play begins.
Now you know.
