繁體中文Card Counting Explained
Card counting is a blackjack technique that tracks the balance of high and low cards. This guide explains the idea, not a how-to system. First, see blackjack and basic strategy.
- Card counting is a blackjack technique that keeps a rough tally of high versus low cards remaining, because a deck rich in high cards slightly favours the player.
- No, it is not illegal, but casinos discourage it through frequent shuffling, multiple decks and shuffle machines that make it impractical.
- Generally no.
The basic idea
Card counting keeps a rough running tally of how many high versus low cards remain, because a deck rich in high cards slightly favours the player. It is a mental estimate, not memorising cards.
Why it can shift the edge
When more high cards remain, certain outcomes become more likely, which is why counters vary their bets with the count.
Why casinos limit it
Card counting is not illegal, but casinos discourage it through frequent shuffling, multiple decks and continuous shuffle machines, which make counting impractical, especially online.
A realistic view
Online blackjack usually shuffles every hand, so counting does not work there. Treat it as a concept to understand, not a strategy to rely on. See gambling myths.
