Red Dog Rules

In casino Red Dog, the dealer turns two cards and announces the spread: the number of ranks between them. Players may then double their bet before a third card is turned. If it falls between the first two, the bet pays according to the spread, from 5 to 1 on a one-card spread down to even money on a wide one.

Also known as Acey-deucey (casino version)

Article 1Objective and equipment

1.1

Red Dog is a house-banked game. All players bet on the same cards against the house. The object is to predict that the third card dealt will rank between the first two.

1.2

The game uses standard 52-card decks, from one to eight shuffled together.

1.3

Cards rank as in poker, with aces high: A, K, Q, J, 10 down to 2. Suits play no part.

1.4

Red Dog is not a poker game in the sense of forming hands, but it is played in casinos alongside poker-based table games and uses poker's card order. A similar home game is In-Between, also called acey-deucey.

Article 2The bet and the first two cards

2.1

Each player places a bet before any cards are dealt.

2.2

The dealer turns two cards face up. There are three possible situations, set out in Articles 3 to 5.

Article 3When there is a spread

3.1

If the two cards are neither equal nor consecutive, the dealer announces the spread: the number of ranks lying strictly between them. For example, 4 and J have a spread of six (5, 6, 7, 8, 9, 10).

3.2

Before the third card is dealt, each player may raise by adding a further bet of up to the amount of the original bet, or may stand.

3.3

The dealer then turns a third card. If its rank falls strictly between the first two, the player's whole bet, including any raise, is paid according to the payout table (Article 6). Otherwise the whole bet loses. A third card equal in rank to either of the first two loses.

Example

A one-card spread

The dealer turns 7♠9♦. The spread is one: only an eight wins.

A player with a 10 bet raises by 10. The third card is 8♣. The 20 bet pays 5 to 1: the player wins 100.

Example

A wide spread

The dealer turns 4♥J♣. The spread is six, which pays 1 to 1.

A player with a 10 bet stands. The third card is J♦, which matches an outside card rather than falling between them. The player loses 10.

Article 4When the cards are consecutive

4.1

If the first two cards are consecutive in rank, such as 5 and 6 or Q and K, no card can fall between them. The hand is a push and every bet is returned. No third card is dealt.

Article 5When the cards are a pair

5.1

If the first two cards are of equal rank, players may not raise. The dealer turns a third card at once.

5.2

If the third card is the same rank, making three of a kind, each bet pays 11 to 1. Otherwise the hand is a push and bets are returned.

Example

Three of a kind

The dealer turns 6♥6♣. The third card is 6♠. A 10 bet pays 11 to 1: the player wins 110.

Article 6Payout table

Payouts vary by casino. This is the standard table.

6.1

The house edge depends on the number of decks, from about 3.2% with one deck to about 2.8% with eight.

Article 7Strategy and related games

  • The chance of winning grows with the spread. The usual advice is to raise only when the spread is seven or more, where the player is favoured to win; players should check an analysis for their deck count.
  • In the home game In-Between (acey-deucey), players bet against a shared pot rather than the house, and a third card matching one of the outside cards usually costs the bettor double.
  • The name Red Dog has also been used for an older, unrelated gambling game in which players bet that they hold a higher card of the same suit as a card turned from the deck.

Article 8Frequently asked questions

What does the spread mean in Red Dog?

The spread is the number of ranks strictly between the first two cards. A 4 and a J have a spread of six: 5, 6, 7, 8, 9 and 10.

What happens if the two cards are consecutive in Red Dog?

The hand is a push. No card can fall between them, so every bet is returned.

Can you raise on a pair in Red Dog?

No. When the first two cards are a pair, the third card is dealt straight away. Three of a kind pays 11 to 1, and anything else is a push.

How much can you raise in Red Dog?

Up to the amount of your original bet, and only when a spread has been announced.
