Blackjack surrender rule

What the blackjack surrender rule is

Surrender is an option to fold. After seeing your first two cards and the dealer's face-up card, you give up the hand, lose half your stake and get the other half back. The Wizard of Odds blackjack basics (opens in a new tab) describe it as available only on the first two cards, and note that some casinos do not offer it. Once you have hit, split or doubled, the option is gone.

It is the only decision in blackjack where you choose a certain loss. That sounds odd, but in a handful of very poor spots a certain loss of half your stake is smaller, on average, than what you would lose by playing on. Our blackjack guide covers the other options, and basic strategy shows where surrender sits in the full chart.

Early surrender v late surrender

There are two versions of the blackjack surrender rule, and the difference is timing against a dealer blackjack.

The values come from the Wizard of Odds rule variations (opens in a new tab) table, measured against an eight-deck, stand-on-soft-17 baseline. Early surrender is worth more because it lets you escape some hands where the dealer has a blackjack. Late surrender against an ace is worth almost nothing under that baseline. When a game simply says 'surrender', it almost always means the late version; the help screen will say which.

Which hands to surrender

For late surrender in 4 to 8 deck games where the dealer stands on soft 17, the Wizard of Odds basic strategy (opens in a new tab) gives a short list: surrender hard 16, except a pair of 8s, against a dealer 9, 10 or ace, and surrender hard 15 against a dealer 10. Nothing else.

The pair of 8s is excluded because splitting it is better, as explained in splitting aces and eights. Soft hands are never surrendered because one card cannot bust them; see soft hands in blackjack. Tables where the dealer hits soft 17 may change some surrender plays, so use a chart built for those rules.

Surrender only applies to your first two cards. A three-card 16 against a 10, such as 7-5-4, cannot be surrendered and is played by the hard-hand chart.

The 25% maths behind surrender

Surrender always costs exactly half your stake, so its expected value is −0.5 stakes. Playing on is better only if the hand's expected value is higher than that. Ignoring pushes, a hand that wins with probability W and loses otherwise has an expected value of W − (1 − W), or 2W − 1. Setting 2W − 1 equal to −0.5 gives W = 0.25. So, if a hand wins less than 25% of the time, surrender saves money on average; if it wins more, play on.

These chances are illustrations of the formula, not the real win rates of particular hands. Pushes complicate the picture slightly, which is why basic strategy charts, built from full calculations, are the place to look for the actual hands. The idea of comparing averages comes from expected value, and the house edge guide shows how these small savings add up.

What the surrender rule is worth in pounds

The rule's value is spread across every hand you play, not only the hands you surrender. Late surrender against a ten is worth about 0.07% of all money staked under the Wizard of Odds baseline; early surrender against a ten is worth 0.24% and against an ace 0.39%.

For context, Wizard of Odds lists blackjack under liberal Las Vegas rules, which include late surrender, at a 0.28% house edge, and Atlantic City rules at 0.43%, as shown on its house edge of casino games (opens in a new tab) page. Late surrender is a small plus; a 6 to 5 blackjack payout costs 1.39% and dwarfs it. See 3:2 vs 6:5 and our blackjack house edge page for the bigger rules.

How to surrender a hand online

1. Open the game's help screen and confirm that surrender is offered, and whether it is early or late.
2. Look at your first two cards and the dealer's face-up card.
3. If you hold hard 16 (not 8,8) against a 9, 10 or ace, or hard 15 against a 10, choose Surrender.
4. Confirm if asked; half your stake is returned and the hand ends.
5. If surrender is not offered, hit those hands instead, and split 8,8.

Which blackjack games offer surrender?

Availability varies widely, so the help screen is the only reliable guide. Some examples from published game analyses:

• Lightning Blackjack (Evolution): Wizard of Odds' Lightning Blackjack analysis (opens in a new tab) reports no surrender, alongside one split only and no double after splitting. See Lightning Blackjack.
• Unlimited Blackjack (Ezugi): Wizard of Odds analyses it as an eight-deck, stand-on-soft-17 game with no surrender.
• Liberal Las Vegas-style rules: the rule set Wizard of Odds uses for its 0.28% figure includes late surrender.
• Branded live games: many add their own rules, such as Six Card Charlie in Infinite Blackjack, so check whether surrender is part of the package.

We don't list which partner tables offer surrender, because the rule depends on each individual game. Check the casino's game lobby and each table's rules.

Surrender v insurance: two very different options

Both options appear when the dealer shows an ace, and both seem to offer protection, but they work differently. Insurance is a side bet of up to half your stake that pays 2 to 1 if the dealer has a ten-value hole card. Wizard of Odds' basic strategy says never take insurance or 'even money'. Surrender is not a bet at all: it is a way to cut your loss on one bad hand, and basic strategy uses it on a handful of specific hands.

The easy rule is: decline insurance every time, and surrender only the listed hands. Our answer to is insurance ever worth it explains the maths.

Surrender mistakes and myths

• "Surrender is for cowards." It is a maths decision. On the right hands it loses less than playing on.
• "Surrender any bad hand." Hard 12 to 14 against a 10 are poor, but they win often enough to play on.
• "Surrender 8,8 against a 10." Split it instead.
• "Surrender when you are on a losing run." Previous hands do not change the odds of the next one; see independent events.
• "Surrender makes blackjack a winning game." Late surrender is worth less than a tenth of a percent; the house still keeps an edge.

Other costly habits are listed on common blackjack mistakes.

Surrender at UK live and RNG tables

There is no Gambling Commission rule requiring or banning surrender; it is a game rule set by the developer and listed in the help screen. In no-hole-card games, common at European and live blackjack tables, check how surrender works, since the dealer has not yet checked for blackjack when you decide. UK rules from 17 January 2025 set a minimum of 5 seconds per round for online casino games other than slots, ban autoplay including at live tables, and require net spend and time played to be shown. Surrender is a good habit precisely because it limits a loss; the same idea applies to your session, and our safer gambling section explains deposit limits and reality checks.

Partner offers and the surrender rule

Whether a table offers surrender has nothing to do with these welcome offers, which are aimed mainly at slots. If you plan to play blackjack, check the terms first: card games are commonly excluded from bonus wagering or count at a fraction of their stake. 18+, terms apply.

See the Casumo blackjack and roulette page for its tables, and game weighting for why blackjack often counts for less.
