Blackjack 101

The Goal

You're not trying to get to 21. You're trying to beat the dealer. If your hand is closer to 21 than the dealer's without going over, you win. If the dealer busts and you don't, you win.

Blackjack Basics

Card Values: Number cards = face value. Face cards = 10. Aces = 1 or 11.

Your Options:

Fun tip: Some casinos let you double for less than your original bet. Don't. It's mathematically worse unless you're literally short on chips.

Basic Strategy

The mathematically optimal play for every hand. Memorize it, and you'll have the lowest possible house edge.

How it works: Look up your hand vs. the dealer's upcard. The chart tells you exactly what to do.

Your Hand Dealer Shows Action
167Hit
166Stand
11AnyDouble
A,76Double
8,8AnySplit

Example: You have 16, dealer shows 10. Basic strategy says hit. Yes, you'll probably bust. But standing loses more often in the long run.

What it's NOT: It's not a guaranteed method to win. Play long enough and you will still lose hands, and still lose money.

House edge: The casino's mathematical advantage. With basic strategy, it's about 0.43% under standard rules, which works out to losing about 43 cents per $100 wagered on average. Without it, you're giving away 2-3%.

The Standard Payout: 3:2

When you get a blackjack, the standard payout is 3:2:

  • Bet $10 → Win $15
  • Bet $20 → Win $30
  • Bet $100 → Win $150

Under standard rules, the house edge with correct basic strategy is 0.43%. In some high-limit rooms with the right rule combinations, the house edge can drop below 0.26%.

The 6:5 Problem

Many casinos now pay 6:5 on blackjack. That one payout change adds 1.39% to the house edge and turns real blackjack into a "carnival game," like most of the other card games on the casino floor.

The Math

Your Bet 3:2 Payout 6:5 Payout You Lose
$10$15$12$3
$25$37.50$30$7.50
$100$150$120$30

House Edge

3:2 Blackjack: 0.43% house edge

6:5 Blackjack: 1.82% house edge

Difference: You lose 1.39% more per hand at 6:5 tables.

That 1.39% penalty is huge. For comparison, baccarat (betting banker only) has a 1.06% house edge. Craps (pass line with full odds) is 0.37%. Video poker (9/6 Jacks or Better) is 0.46%. At 1.82%, 6:5 blackjack is worse than all of these.

How They Get You

Low minimums. They offer $5 at 6:5 tables, $25 at 3:2. Don't fall for cheap minimums.

Location. 6:5 tables up front. Real blackjack games with 3:2 payouts in back, off the main path, or in the High Limit room.

Small print. "Blackjack pays 6:5" is buried in tiny letters on the felt or screen. Can't find it? Ask the dealer or pit boss. They won't be happy you asked, but better that than finding out after your first blackjack.
