Card values and 21
Number cards count at face value. Tens, jacks, queens and kings count as 10. An ace can count as 1 or 11, which is why a hand with an ace may be described as soft. A total above 21 is a bust, so the hand loses under the usual rules.
The useful detail is the one that changes the decision in front of you: the total stake, the next card, the betting window or the rule for this table.
What happens after the deal
Players normally receive two cards; the dealer has a visible card and a concealed card in many versions. Depending on the hand and table rules, choices can include taking another card, standing, splitting a pair, doubling, or sometimes surrendering. Read the table rules before assuming an option is offered.
Keep the general guide and the venue’s current terms separate. Both are needed for a practical plan.
Use the table in front of you
Rules, minimums and dealer procedures vary between versions. Ask a member of staff to explain an unfamiliar term before a wager is committed. Understanding the options can help you follow a hand, but it does not make a loss impossible.
Before travel, confirm the venue’s current entry, access and session information. That practical check does not change the game rules, but it prevents a general guide from standing in for live information.
The dealer’s required action and the availability of options such as splitting or doubling are table rules, so read them before acting.
