Las Vegas Blackjack Rules (2024)

There are many different types of Las Vegas blackjack games, even at the same casino. The rules determine the house advantage in the game. The lower the house advantage, the more likely it is the player wins. Here are some of the house rules that determine the advantage the casino has over the player.

Blackjack pays 3/2 or 6/5

The most important blackjack rule is if blackjack pays 3/2 or 6/5. The 3/2 payout is best for the player. A 6/5 blackjack game has a house edge that is 1.39% higher than the 3/2 payout.

Players will find 3/2 blackjack all over the locals market and at most downtown casinos. Most Las Vegas Strip casinos deal 3/2 blackjack. However, the minimum bet is usually at least $25. It may be $50 or $100.

Double down

All live Las Vegas blackjack games allow double down before splitting. Alamo is the only casino that only permits it on 10 and 11 before splitting.

Alamo, Boyd Gaming’s downtown Las Vegas casinos, El Cortez’s single-deck, the even money Poker Palace game, and most Caesars double-deck tables don’t allow double down after splitting.

There is an odd double down rule at the 3/2 tables at Poker Palace. Players may double down on two or three cards. At Most Liberal 21 and Spanish 21, double down is allowed on up to four cards before and after splitting.

Many Game King blackjack games do not allow double down at all. That increases the house advantage by about 1.5%. This is one of many reasons to avoid those machines.

Surrender

Surrender is available at dozens of Las Vegas blackjack tables. It is only allowed at six-deck and eight-deck blackjack games. It is never offered at single-deck or double-deck ones.

When surrender is available, the player folds and the house takes half the bet. This drops the house edge by 0.07%. Surrender is also offered at some blackjack variants like Spanish 21 and Most Liberal 21.

Re-split aces

Re-split aces means that players can split again when the first split of aces makes another pair. Split aces may not be hit, except at variants like Most Liberal 21 and Spanish 21. This reduces the house advantage by 0.08%.

All six-deck and eight-deck blackjack games dealt at MGM Resorts and Treasure Island allow re-split aces. The high-limit tables at Caesars Palace, Sahara, M Resort, and Station Casinos also permit this at six-deck games.

There are a few double-deck tables in Las Vegas that allow aces to be re-split. This includes Station Casinos and M Resort high-limit tables.

Hit or stand on soft 17

The dealer hitting or standing on soft 17 is a major blackjack rule. All tables under $50 in Las Vegas hit soft 17. Many high-limit tables stand on it. Most deal six decks. A few MGM Resorts tables, as well as Treasure Island, have this favorable rule at high-limit double-deck tables. The dealer standing on soft 17 drops the house advantage by 0.22%.

Hit split aces

When a player is dealt two aces, splitting is allowed. As described above, some blackjack tables allow aces to be split again if another is dealt. No standard blackjack tables allow the player to hit after splitting aces. However, Most Liberal 21 and Spanish 21 allow players to do this. Both games also let players double down after splitting aces. This reduces the house advantage by 0.2%.

Dealer pushes on 22

Free Bet Blackjack is by far the most popular variant in Las Vegas. Players receive free splits and doubles in this game. To offset this, the dealer pushes all players left in the hand when making 22. Players dealt a blackjack get paid as normal. Busted players still lose.

Mandatory side bets

There is a terrible blackjack game in downtown Las Vegas called Bonus Spin that requires a $1 or $2 side bet. This is the worst blackjack game in Las Vegas. The house advantage on the worst version of it is 8.95% at the minimum bet. This game is found at Binion’s, Four Queens, Fremont, and Golden Nugget.
