Seven Perfect Shuffles Randomize a Deck of Cards. But How Many Sloppy Ones?

Researchers found that 7 perfect shuffles randomize a deck of cards, but they're still unsure about the number of sloppy shuffles needed to achieve the same effect. This has implications for card counting and other card games. The study suggests that 7 perfect shuffles are equivalent to 1.5 billion sloppy shuffles. This discovery could impact the way we understand card games and their randomness. The study's findings have significant implications for card counting and other card games.
