In Between Rules

In In Between, also called Acey Deucey, each player in turn is dealt two cards face up and bets against the pot that the next card will fall between them in rank. A card between wins the bet from the pot; a card outside loses it to the pot; and a card matching either end, called hitting the post, costs double.

Article 1Players, deck and objective

1.1

In Between is a betting game played with poker chips, often dealt in home dealer's choice games. It is not poker: no poker hands are made. Each player bets alone against the pot.

1.2

A standard 52-card deck is used, with no wild cards. Cards rank from two (low) to king, with the ace high or low as set out in article 4.

1.3

Two to about eight players may take part. The object is to win chips from the pot by predicting correctly that a third card will fall strictly between two cards already dealt.

1.4

The casino game Red Dog is a house-banked relative of In Between, with payouts set by the size of the spread.

Article 2Antes and each player's turn

2.1

Before play begins, every player puts an agreed ante into the pot.

2.2

Starting with the player to the dealer's left, and going clockwise, the dealer deals the player two cards face up.

2.3

The player then either bets that the next card will fall between the two, or declines to bet. A player who declines simply passes, and their cards are discarded.

2.4

Size of the bet. The limit shall be agreed before play. The usual conventions are:

2.4(a) during the first round, a bet is often equal to the ante, and at most half the pot;

2.4(b) once every player has had at least one turn, a player may bet up to the whole pot;

2.4(c) a bet may never exceed the amount in the pot.

2.5

When the bet is placed, the dealer deals a third card face up.

Article 3Settling the bet

3.1

The result depends on the rank of the third card:

3.1(a) Between: if its rank lies strictly between the first two cards, the player wins and takes the amount of the bet from the pot.

3.1(b) Outside: if it is higher than both or lower than both, the player loses and pays the bet into the pot.

3.1(c) The post: if it matches the rank of either of the first two cards, the player has hit the post and pays double the bet into the pot.

3.2

If the pot is emptied, every player antes again to start a new pot.

3.3

When the deck runs out, the discards are shuffled to form a new deck and play continues.

3.4

Consecutive cards. If the first two cards are consecutive in rank, such as a five and a six, no card can fall between them. A player in this position would normally decline to bet.

3.5

Pairs. Groups differ on what happens when the first two cards are a pair. A common rule is that the player may bet that the third card will be higher or lower than the pair; if the third card is of the same rank again, the player pays three times the bet. The dealer shall announce the rule before play.

Example

A winning spread

A player is dealt 4♥J♦. Any five, six, seven, eight, nine or ten wins: six ranks, or 24 of the 50 unseen cards.

The player bets 5, and the third card is 8♣. The eight falls between the four and the jack, so the player takes 5 from the pot.

Example

Hitting the post

A player is dealt 3♠10♥ and bets 4. The third card is 10♣.

The ten matches one of the first two cards, so the player has hit the post and pays double: 8 into the pot.

Article 4Aces

4.1

If the first card dealt to a player is an ace, the player shall declare it high or low before the second card is dealt.

4.2

Sources differ when the ace is the second card. Some rules let the player choose high or low before betting; others treat a second-card ace as always high. The dealer shall announce which rule applies.

4.3

A low ace followed by a high ace gives the widest possible spread: any two to king wins.

Example

Choosing high or low

A player's first card is A♠ and they declare it high. The second card is 6♦. Any seven to king wins: seven ranks.

Had the player declared the ace low, only a two, three, four or five would win: four ranks.

Article 5Common variations

  • Posts on an ace may be charged at a higher multiple, such as four times the bet.
  • Some groups play with two decks shuffled together.
  • Some add a blind bet, placed before the player sees any cards, or a rule that an ace-deuce spread must be bet for the whole pot.

Any such rule shall be agreed before play begins.

Article 6Frequently asked questions

What happens if you hit the post in In Between?

If the third card matches either of your first two cards in rank, you lose and pay double your bet into the pot.

Is an ace high or low in Acey Deucey?

If your first card is an ace, you choose high or low before the second card is dealt. Rules for an ace as the second card vary: some let you choose, others treat it as high.

How much can you bet in In Between?

The limit is agreed in advance. A common rule caps early bets at half the pot and allows bets up to the whole pot once everyone has had a turn. You can never bet more than the pot.
