Free Bet Blackjack strategy

Free Bet Blackjack is a popular Las Vegas variant that lets you double and split without putting up more money. The house matches the extra bet with a “free bet” button. That sounds like a gift, and in part it is. But every live hand pushes when the dealer finishes on exactly 22. That rule alone is worth about 6.9% to the house. The result is a game that rewards aggression in the right places and punishes regular-blackjack habits. Knowing exactly when to take the free bets, and how the 22 push changes your stiff hands, is the whole strategy.

How to play

1. Bet. The standard game uses 6 decks. The dealer hits soft 17 and blackjack pays 3:2.
2. The deal. You get two cards. The dealer shows one upcard.
3. Take your free bets. With a two-card hard 9, 10 or 11, you may double for free: the dealer puts a free-bet button next to your wager. With any pair except 10s, you may split for free: the second hand plays on a free bet. Free doubles are also allowed after a split, and you can split up to four hands.
4. Paid options still exist. You may double other two-card hands (like soft 18) or split 10s, but with your own money.
5. Play out your hand as usual. There is no surrender.
6. The dealer plays. If the dealer ends on exactly 22, every live hand pushes. Player blackjacks still win.
7. Settle. A free bet pays when its hand wins and costs nothing when it loses or pushes.

Payouts

Here is how the money works. You bet $10 and get 6♦ 5♣ against a dealer 9. You take the free double, and the dealer sets a $10 free-bet button next to your chips. If you win, you collect $20 on top of your $10 bet, just as if you had doubled with your own money. If you lose, you lose only your $10. Free splits work the same way: split 8♠ 8♥ for free, and if the second hand loses, it costs you nothing. If it wins, it pays $10.

Strategy

Casino Coach derives the Free Bet chart from its exact infinite-deck engine, with the free-bet payoffs and the 22 push modeled. A 250,000-round shoe simulation checks it. The trainer has the full chart. Here are the rules that matter for the standard game (6 decks, H17).

Rule 1: take every free bet

The logic is simple. A free double or free split can only add money to your hand, never cost you more. So 8♠ 8♥ against a dealer 10 is a free split, and so is 4♦ 4♣ against a 9. Splitting 9,9 against an ace and doubling 10 against a 10 are free plays too.

Rule 2: stiff hands, adjusted for the 22 push

When the dealer busts with exactly 22 you don’t win, you push. That makes a weak upcard slightly less of a gift, so the borderline stands against a 2, 3 or 4 become hits.

Rule 3: soft hands double less

Soft doubles are paid with real money, so they are rarer than in regular blackjack:

One simplification: Casino Coach plays hands riding a free bet with the same strategy as real-money hands. Wizard of Odds notes that the optimal free-hand strategy is slightly more aggressive.

Common mistakes

Costs are per hand, in units of your bet, vs the correct Free Bet play, as computed by Casino Coach for 6D H17:

• Hitting a pair instead of free-splitting it. Hitting 7,7 or 3,3 against an 8 costs about 0.52 bets. 6,6 vs 7 costs about 0.49.
• Standing on 9,9 vs an ace or 10. Costs about 0.48 and 0.39 bets. Take the free split.
• Skipping the free double on 10 or 11 against a 10 or ace. Hitting 10 vs 10 costs about 0.33 bets.
• Not free-splitting 4,4. Hitting it against a 4 costs about 0.39 bets.
• Doubling soft hands like regular blackjack. Soft doubles here use your own money. Only soft 17 vs 6 and soft 18 vs 5–6 qualify.
• Playing the Push 22 side bet. About 11.8% to the house, every time.

House edge explained

The free doubles and splits are worth a lot. The 22 push is worth more. A dealer 22 happens about 7.4% of the time in a 6-deck H17 game. Every time it does, hands that would have won push instead. Per Wizard of Odds, the standard rules give the house 1.04%. Casino Coach’s 250,000-round simulation measures 1.10%. Rule changes to look for:

The best version you’re likely to find is S17 at 0.73%. Avoid 6:5 tables, which push the edge well past 2%.

Practice in Casino Coach

Casino Coach deals Free Bet Blackjack from a real 6-deck shoe with free chips, and the free-bet buttons settle exactly as they do in the casino. In trainer mode every decision is graded against the exact optimal play. A mistake shows the EV of every option, and you can block wrong moves until you correct them. The Strategy tab shows the full chart with free plays marked, EVs on hover, an H17/S17 toggle and a ranked list of the regular-blackjack habits that cost you here. The drills are adaptive Strategy Flashcards (all hands or habit breakers) and Free Bet Settlement, which tests what each hand actually wins or loses when real and free chips are mixed. Analytics tracks your accuracy and the EV your mistakes cost. Train free and make taking every free bet automatic.
