“In-Between” can refer to a blackjack side bet in which the dealer’s upcard is compared with the player’s first two card ranks. The posted rules and paytable—not the name—determine the return.
What is an In-Between side bet?
In a common concept, the side wager wins when the dealer’s upcard rank falls strictly between the ranks of the player’s first two cards. Some versions also pay for a three-card rank match. Terms such as “between,” ties, aces and duplicate player ranks must be defined by the exact game rules.
The side bet is separate from the main blackjack wager. The main game can use different payouts, deck counts, dealer soft-17 rules and player options, so do not assume that every table carrying the side bet uses the same blackjack rules.
Example of the basic event
If the player receives a 2 and a 10, dealer upcards from 3 through 9 fall strictly between those ranks. Whether each result wins, and how much it pays, must be checked on the table’s posted paytable. A narrow interval may pay more than a wide interval, but payout schedules are configurable and can change the house edge.
A three-card match—such as player 10, player 10 and dealer 10—may be a separate top award. Read “rank” carefully: 10, jack, queen and king all count as ten points in the main game, but they are distinct ranks for an interval-based side bet. Three ten-point cards are not necessarily a triple match.
A documented paytable and how to read it
Michael Shackleford’s In BETween analysis documents these profit payouts: triple match 30:1; one intervening rank 10:1; two 6:1; three 4:1; wider winning intervals 1:1. These figures describe that analyzed schedule, not every similarly named wager.
“One intervening rank” means a player 5 and 7 need a dealer 6. It does not mean that adjacent player ranks, such as 5 and 6, have room for a winning card. A dealer card matching an endpoint is not strictly between them. A special three-card match is a separate event, not an endpoint tie winning the ordinary interval award.
For a $2 side wager paying 10:1, the profit is $20 and the total returned is $22, including the $2 stake. At 1:1, the profit is $2 and the total returned is $4. Confirm whether a displayed payout is profit “to one” or a total return “for one”; confusing those conventions changes the calculation.
Why a narrow gap pays more
Consider a single, freshly shuffled 52-card deck with no other exposed cards. After a player receives a 5 and 7, four sixes remain among 50 unseen cards. The conditional chance that the dealer’s upcard is a 6 is 4/50, or 8%. With a 2 and 10 instead, seven intervening ranks contain 28 cards: 28/50, or 56%. This simple comparison explains why an interval with fewer winning ranks can carry a higher payout.
Those are probabilities after seeing a particular player hand, not the overall return of the side bet. The wager is normally made before those cards are known. To calculate its house edge, include how often every possible player pair occurs, the triple-match event, every winning payout and all losing outcomes. Other exposed cards or a depleted shoe also change the conditional denominators and rank counts.
House edge
The house edge cannot be calculated from the game name or deck count alone. It requires the complete paytable, treatment of aces and ties, number of decks, replacement or shuffle procedure and any special match awards.
More decks do not automatically make every version better. Ask for the written rules and calculate the expected return for the exact paytable. If the operator cannot provide them, skip the wager.
For that documented paytable, the detailed return tables give house edges of approximately 10.46% with one deck, 7.76% with two, 6.04% with four, 5.42% with six and 5.10% with eight. These are starting-shoe calculations under the analysis assumptions.
Keep side-bet turnover separate
Using a 5.42% edge as a rounded example, 100 side wagers of $2 create $200 of turnover and an expected loss of about $10.84. This does not predict a $10.84 loss on your next session: actual results arrive as discrete wins and losses, with occasional large awards. If your main blackjack bets total $1,000, the side-bet edge applies to its own $200, not to the combined $1,200. Add the expected costs of the two wagers separately.
Can card counting change the wager?
Removing cards changes the probabilities of later ranks, so a defined side bet can in principle be analyzed for composition sensitivity. That observation is not evidence that the wager is practically beatable. A valid claim requires a published or reproducible analysis of the exact rules, sufficient penetration, an actionable betting point and realistic variance.
A high concentration of ten-valued cards alone does not prove an edge. It can affect both match and between outcomes, and the paytable determines whether those changes overcome the house advantage.
Availability and ownership
Side-bet catalogues and placements change. An old manufacturer page or a report from one region does not establish current availability, popularity or ownership in every market. Verify the table signage, game manufacturer and regulator approval at the property where you plan to play.
Frequently asked questions
Is In-Between safer than other side bets?
No such conclusion follows from the name. Compare house edge, variance, maximum exposure and complete rules.
Does the dealer still follow ordinary blackjack rules?
The side wager does not itself define the main game. Read the table’s blackjack rules separately.
Should I play without a published paytable?
No. You cannot evaluate the expected return or confirm the settlement rules without it.
