  • Insurance is a bad bet for most players, with a house edge above 7%.
  • 100cuci lists live blackjack. We could not verify the table rules it uses.

100cuci lists blackjack in its live casino category (checked 3 November 2026). We could not verify the exact rules at each table, so the figures below are standard estimates for 4 to 8 decks. Check the table's rules panel before you play.

Basic blackjack rules

  • Goal: a higher total than the dealer without going over 21.
  • Card values: 2 to 10 at face value, J/Q/K = 10, A = 1 or 11.
  • Blackjack: an A with a 10-value card as your first two cards. Standard tables pay 3:2.
  • Your options: hit (take a card), stand (stop), double (double your bet and take exactly one card) or split (turn a pair into two hands).
  • The dealer has no choice: it must draw until 17 or more. Some tables make the dealer hit on soft 17 (A and 6).
  • Bust: if you go over 21 you lose immediately, even if the dealer busts later. This is the main source of the house edge.

Basic strategy: the decisions that matter most

Basic strategy is the mathematically best decision for every combination of your hand and the dealer's up card. The summary below covers the situations that come up most often.

With a 3:2 payout, the dealer standing on soft 17 and correct basic strategy, the house edge at an 8-deck table is usually around 0.5%. Strategy mistakes can add more than any bad table rule.

Table rules that raise the house edge

RuleApproximate effect
Blackjack pays 6:5 instead of 3:2Adds about 1.4%
Dealer hits soft 17Adds about 0.2%
No double after splitAdds about 0.1%

On a RM10 bet, a 3:2 blackjack pays RM15, while 6:5 pays only RM12. That RM3 looks small, but it happens on every blackjack you get.

Insurance and side bets

When the dealer's up card is an A, you're offered insurance: a bet of half your original stake that the dealer has blackjack, paying 2:1. It sounds like protection, but it's a separate bet.

About 4 in every 13 cards are worth 10, so the dealer has blackjack less than a third of the time. At 2:1, you need at least one in three just to break even. As a result, insurance usually carries a house edge above 7%. "Even money", offered when you have blackjack and the dealer shows an A, is insurance under another name.

Side bets such as Perfect Pairs or 21+3 usually have a much higher house edge than the main bet. Check the payout table in the rules panel.

Before you sit down at a live blackjack table

  • Make sure blackjack pays 3:2, not 6:5.
  • Check whether the dealer stands or hits on soft 17.
  • Keep a basic strategy chart next to you. Using one isn't cheating.
  • Work out your expected loss: RM20 × 100 hands = RM2,000 wagered. At about 0.5%, that's an expected loss of about RM10. At a 6:5 table (about 1.9%), about RM38.
  • Set time and money limits. See the responsible gambling guide.

Frequently asked questions

Can I beat blackjack with basic strategy?

Basic strategy reduces the house edge, usually to around 0.5% with good rules, but doesn't remove it. Over the long run you're still expected to lose.

Should I take insurance?

For most players, no. The dealer has blackjack less than a third of the time, but insurance only pays 2:1, so its house edge is usually above 7%.

What's the difference between 3:2 and 6:5 blackjack?

On a RM10 bet, a 3:2 blackjack pays RM15 while 6:5 pays RM12. The difference adds about 1.4% to the house edge.
