The payout matters most. On ₦500,000 of total bets, a 6:5 table costs about ₦7,000 more in expected losses than a 3:2 table.
Core plays
- Always split aces and eights.
- Never split tens or fives.
- Stand on hard 17 or more.
- Hit hard 12 to 16 against a dealer 7 or higher; stand against 2 to 6, except hit 12 against 2 or 3.
- Double 11 against every dealer card except, on some rule sets, an ace.
- Do not take insurance.
Live and RNG tables
The same chart applies to both. RNG blackjack reshuffles every hand and plays faster, so the same stake costs more per hour. Live tables have fixed minimums and a slower pace, and some new formats such as Infinite Blackjack change side rules; check the info panel.
Counting cards online
Card counting does not work usefully online. RNG games reshuffle every hand, and live tables use continuous shufflers or cut deep into the shoe.
Bankroll and bonuses
Set a session budget and a unit of 1% to 2% of it. Most welcome offers count blackjack at 10% to 20% toward wagering or exclude it; at 10%, a 40x requirement is effectively 400x. Read the terms before you claim.
How blackjack basic strategy is built
Blackjack basic strategy is a fixed table of decisions. Blackjack basic strategy comes from simulating millions of hands and recording which action loses least for each player total against each dealer up-card. The table assumes you see only the cards on the felt and nothing else. It therefore cannot make the game profitable; it removes the extra cost of guessing.
Blackjack returns most of every stake over a long run. A game with a 0.5% house edge pays back about 99.5% of what is staked. The link between house edge and RTP is covered in our guide to RTP at new online casinos. Any single session can still finish well above or below that figure.
On Atlantic City rules, blackjack basic strategy leaves a house edge of 0.43%.
Blackjack hard totals, soft totals and pairs
Basic strategy sorts every starting hand into three groups. Hard totals contain no ace, or an ace that must count as 1. Soft totals contain an ace counted as 11, so one more card cannot bust the hand. Pairs are two cards of equal value, and they are the only hands you can split. Each group has its own section of a chart, and you read the row for your hand against the dealer's up-card.
Soft hands allow bolder play because they cannot bust on the next card. Soft 18, an ace and a seven, is a good example. The chart stands it against a dealer 2, 7 or 8 and hits it against a 9, 10 or ace. Most charts double it against a dealer 3 to 6 where doubling is allowed.
Practise one group at a time before you play for money. Memorising a fixed table is a habit that carries across card games at new casinos. Our tips for playing new casino card games cover how to build that habit.
Why 6:5 blackjack raises the house edge
A 6:5 payout pays ₦6 for every ₦5 staked on a natural, where a 3:2 payout pays ₦7.50. Naturals arrive often enough that the smaller payout is felt in every session. The saving looks small on one hand and large over thousands.
A 6:5 payout adds 1.39% to the house edge.
A dealer who hits soft 17 adds 0.22% to the house edge.
On a six-deck table where the dealer hits soft 17, basic strategy with a 3:2 payout carries a house edge of 0.46%.
Is blackjack insurance worth taking?
Insurance is a side bet offered when the dealer shows an ace. Insurance costs half your original stake and pays 2:1 if the dealer holds a ten underneath. Basic strategy declines it because the dealer holds a ten less than a third of the time.
On a six-deck game, the insurance bet carries a house edge of 7.4%.
Choosing live or RNG blackjack at new casinos
Live blackjack streams a real dealer from a studio and runs at the dealer's pace. RNG blackjack deals from software and runs as fast as you click. Both use the same basic strategy chart, so the choice depends on pace and rules rather than on the plays.
Check the payout first, because 6:5 tables appear in both formats. Tables at the same casino can differ in rules. Compare live lobbies in our list of new live casinos, then open the info panel at each table before you stake.
