Why gestures are used
On a live blackjack table, a player’s decision is communicated by a visible gesture, often together with a spoken word. The gesture is the official signal. There are three practical reasons.
First, casinos are noisy, and a quiet “hit” can be misheard. Second, many tables use overhead cameras with no audio, and a gesture is recorded in a way that words may not be. If a player later says they asked for a card but did not, footage shows what they actually did. Third, some players share a language poorly with the dealer, and a gesture crosses that gap.
For these reasons, speech alone is generally not treated as enough. A dealer may repeat your decision aloud to confirm, and if there is doubt the dealer will usually ask you to clarify with a clear signal. The gestures below are the common ones, but exact conventions vary between casinos, so follow the dealer if you are told otherwise.
Shoe games: cards face up
In a shoe game, cards are dealt face up and players do not touch them. This is the most common setup, and the signals are made with one hand.
Hit. Tap the table lightly with a finger, or scratch the felt towards yourself, beside your cards. This asks for one more card. Repeat the signal each time you want another card; the dealer will not assume you want a second one.
Stand. Wave your hand flat, palm down, from side to side over your cards. This means no more cards. Some players move the hand horizontally just above the felt, which is the clearest form.
Double down. Place an additional bet equal to your original wager beside it, and hold up one finger. The extra bet should be placed next to your original stack, not on top of it. Rules limit when you can double, depending on the table.
Split. When your first two cards are a pair, place a second bet equal to the first beside the original, and show two fingers in a V shape. The dealer then separates the cards into two hands. Resplitting and doubling after a split are subject to table rules, as covered in the article on resplit limits.
Hand-held games: cards face down
In a game where cards are dealt face down and players pick them up, the signals are different. Players may hold the cards with only one hand and must keep them above the table.
- Hit: gently scrape the edge of the cards on the felt towards yourself.
- Stand: slide the cards under your bet, tucked beneath the chips.
- Double or split: turn the cards face up, place the additional bet beside the first, and give the same finger signal as in the shoe game.
The one-hand rule is meant to discourage bending or marking cards. Touching the cards is only for the player who holds them.
Other signals you may need
Several decisions outside the main four also use a gesture, and these vary more:
- Surrender: where it is offered, many tables expect you to draw a line behind your bet with a finger, as if cutting it in half, and say “surrender”. Some tables accept only certain situations, so check the posted rules. The idea is covered in the discussion of late surrender.
- Insurance: you place a bet up to half your original wager on the insurance line when offered, usually without a hand gesture. Whether it is a good bet is a separate topic, covered under the insurance bet.
- Even money: if you hold a natural and the dealer shows an ace, you may be offered even money. You answer verbally and by gesture. The choice is explained under even money.
Common mistakes
- Using speech only. The dealer may stop and ask for a signal, which slows the game.
- Signalling after the dealer has moved on. Once the dealer begins the next spot, your decision may be treated as final.
- Changing your mind mid-gesture. Most dealers will act on the first clear signal.
- Double or split without the extra bet. The gesture is incomplete until the chips are on the table. Place the chips first or at the same time as the signal.
- Touching your cards in a shoe game. This can be treated as a breach of procedure.
If you are not sure which signal to use, ask the dealer before play begins. It is a normal question, and dealers are used to it.
Why precision helps you
Signals do not affect the odds. Nothing about the way you tap or wave changes the cards that come out or the house edge. The value of clear gestures is that your intended decision is the one the dealer carries out. Misread decisions are a common source of table disputes, and clear signals prevent most of them.
Learning the gestures is part of general table etiquette. Practise them at home before a first visit if you want to feel comfortable. Blackjack outcomes are uncertain and usually run against the player over time, gambling can be harmful, and you should only play with money you can afford to lose.
