Blackjack rewards skill more than any other casino game. Two players sitting at the same table can produce wildly different long-run results — one playing optimally, the other guessing. The single most valuable thing you can do at a blackjack table is print a basic-strategy chart and follow it religiously.
How blackjack works (the short version)
Beat the dealer's hand without going over 21. Cards 2–10 count their face value, J/Q/K count 10, Ace counts 1 or 11. You're dealt two cards; you can hit, stand, double, split (matching pair) or surrender (some games). Dealer hits to 17, stands on 17.
Best blackjack variants online
Look for: single-deck or double-deck, 3:2 blackjack payout (avoid 6:5 — it adds 1.4% to the house edge), dealer stands on soft 17, double after split allowed. The best online variants: Microgaming Vegas Single Deck, Playtech Blackjack Switch, NetEnt Classic Blackjack.
Basic strategy in 60 seconds
Always split aces and 8s. Never split 5s or 10s. Double on 11 against dealer 2-10. Hit soft 17 or lower; stand on hard 17+. Stand on 12-16 against dealer 2-6 (dealer is likely to bust). Hit 12-16 against dealer 7-A.
Memorize these or print a chart. The chart is legal at every online table — there's no one stopping you from referencing it.
Side bets and live blackjack
Side bets (Perfect Pairs, 21+3, Insurance) carry 4–10% house edges. Skip them. Live dealer blackjack from Evolution Gaming has the same odds as RNG but a much better experience. Lightning Blackjack adds multipliers at a slight RTP cost — fun, but worse EV than standard live.
