A craps hardway is a multi-roll wager that wins only when a total appears as a matching pair before either the same total appears the “easy” way or a 7 is rolled. The usual house edge is 9.09% on hard 6 and hard 8 and 11.11% on hard 4 and hard 10.
Those percentages come from a simple pricing gap. Each hardway has one winning dice combination. The casino pays one unit less than the bet’s true odds.
| Bet | Winning roll | Easy-way losses | Other loss | Common payout | True odds | House edge |
|---|---|---|---|---|---|---|
| Hard 4 | 2-2 | 1-3, 3-1 | Any 7 | 7 to 1 | 8 to 1 | 11.11% |
| Hard 6 | 3-3 | 1-5, 5-1, 2-4, 4-2 | Any 7 | 9 to 1 | 10 to 1 | 9.09% |
| Hard 8 | 4-4 | 2-6, 6-2, 3-5, 5-3 | Any 7 | 9 to 1 | 10 to 1 | 9.09% |
| Hard 10 | 5-5 | 4-6, 6-4 | Any 7 | 7 to 1 | 8 to 1 | 11.11% |
Other totals do not win or lose the bet. They merely leave it unresolved.
Why only resolving rolls enter the house-edge calculation
Consider hard 6. There are 36 equally likely ordered outcomes when two fair six-sided dice are rolled.
The bet resolves on 11 of them:
- one winning combination: 3-3;
- four easy-six combinations: 1-5, 5-1, 2-4, and 4-2;
- six combinations totaling 7.
The other 25 combinations do nothing to the wager. Conditioning on the rolls that actually settle it gives:
[ P(\text{win}\mid\text{hard 6 resolves})=\frac{1}{11} ]
[ P(\text{lose}\mid\text{hard 6 resolves})=\frac{10}{11} ]
A fair profit payout would therefore be 10 to 1. The common casino payout is 9 to 1.
For a one-unit stake, expected value is:
[ EV=\left(\frac{1}{11}\times 9\right)-\left(\frac{10}{11}\times 1\right) =-\frac{1}{11} ]
The house edge is the expected loss divided by the original stake:
[ \text{House Edge}=\frac{1}{11}=9.0909% ]
Hard 8 has the same structure and therefore the same edge.
Hard 4 and hard 10 resolve on nine combinations: one hardway, two easy ways, and six sevens. At a 7-to-1 payout:
[ EV=\left(\frac{1}{9}\times 7\right)-\left(\frac{8}{9}\times 1\right) =-\frac{1}{9} ]
[ \text{House Edge}=\frac{1}{9}=11.1111% ]
The result does not depend on how many harmless rolls occur first. Waiting changes the duration of the wager, not its price.
What the percentages mean in money
A $10 hard 6 or hard 8 has an average loss of:
[ 10\times 0.090909\approx $0.91 ]
per completed wager.
A $10 hard 4 or hard 10 has an average loss of:
[ 10\times 0.111111\approx $1.11 ]
per completed wager.
These are long-run averages, not predictions for one attempt. A hard 6 can win $90 immediately, lose on the next roll, or remain active through several unrelated totals. The house edge describes the average result over many similarly priced decisions.
It is also useful to separate profit payout from total return. “9 to 1” means a winning $5 hard 6 earns $45 in profit and the original $5 stake is returned, for $50 back in total. The distinction is explained further in Payout: Profit, Return, and Settlement.
A long wait does not make the bet safer
Hardways often feel less severe than one-roll proposition bets because they can survive many rolls. That impression comes from duration, not lower mathematical cost.
On any roll, hard 6 or hard 8 resolves with probability:
[ \frac{11}{36} ]
The expected number of rolls until resolution is therefore:
[ \frac{1}{11/36}=\frac{36}{11}\approx 3.27 ]
Hard 4 or hard 10 resolves with probability 9/36, so the expected wait is four rolls.
“Expected” is not a countdown. A bet can settle immediately or remain up much longer. Every non-resolving roll simply returns the wager to the same state: one hard combination wins; the easy total or 7 loses.
This is also why a hardway does not become due after several misses. Previous non-deciding rolls do not improve the next roll’s probability.
Hard 6 is not the same bet as place 6
Both bets involve the total 6, but they pay for different events.
A place 6 wins on all five combinations totaling 6 and loses on the six combinations totaling 7. At the standard 7-to-6 profit payout, its expected value per unit wager is:
[ EV=\left(\frac{5}{11}\times\frac{7}{6}\right)-\left(\frac{6}{11}\times1\right) =-\frac{1}{66} ]
That is a house edge of approximately 1.52%.
A hard 6 rejects four of those five winning sixes and pays only when 3-3 appears before an easy 6 or 7. Its 9.09% edge is about six times the place-bet edge.
The larger 9-to-1 headline payout does not make hard 6 the better price. It compensates for a much narrower winning condition, and not quite enough to match fair odds. For a practical comparison, see Place 6 and 8 Strategy and Hardways Explained.
House edge per decision versus expected loss per roll
House edge is conventionally stated per original wager when the bet resolves. Because a hardway may remain active through several rolls, an operator or player estimating hourly action may also look at expected loss per roll.
For a continuously working $10 hard 6, one of the 36 dice combinations wins $90, ten combinations lose $10, and 25 produce no decision:
[ EV_{\text{per roll}}= \left(\frac{1}{36}\times90\right) -\left(\frac{10}{36}\times10\right) =-\frac{10}{36}\approx-$0.28 ]
The same result can be reached by multiplying the loss per completed bet by the probability of resolution:
[ $10\times\frac{1}{11}\times\frac{11}{36}=\frac{$10}{36} ]
At the common payouts, a $10 hard 4 also loses $10/36 on average per working roll: the one winning combination earns $70, eight resolving combinations lose $10, and all other rolls leave the bet up.
This does not mean all four bets have the same house edge. Hard 4 and hard 10 resolve less often, so the same average shortfall per working roll is divided across fewer completed wagers. Their edge per completed wager is therefore higher.
An hourly estimate must also know the number of rolls, whether the wager is working on come-outs, how often it is taken down, and whether wins are pressed. Multiplying the headline edge by an arbitrary “bets per hour” count can overstate or understate action when the same chip remains on the layout for several rolls. The Expected Loss per Hour page develops that distinction.
How the bet is booked and settled
Hardways sit in the proposition area controlled by the dealer crew. A player normally tosses chips toward the center and states the number and amount, such as “five-dollar hard eight.” The dealer repeats the call and positions the wager in the appropriate player location.
The sequence matters because the chips are not self-service bets. Before the dice leave the shooter’s hand, the crew must know:
- which player owns the wager;
- which hard number is covered;
- the amount;
- whether the bet is working or off;
- whether any press or take-down instruction was accepted in time.
After a winning hardway, the dealer pays the posted odds and usually leaves the original wager up unless the player instructs otherwise or house procedure requires a different handling. On an easy version or 7, the bet is collected.
Common dispute points include an unclear verbal call, chips arriving after “no more bets,” a player assuming the bet was working, an improper payout multiple, or confusion over whether winnings were pressed. Clear calls and dealer confirmation are more reliable than gestures from a crowded rail.
Working on the come-out roll
Hardways are often handled as inactive on the come-out roll unless the player calls them working and the dealer confirms the instruction. That is not a universal rule to assume without checking.
The Massachusetts Gaming Commission’s official craps and mini-craps rules provide one regulated example: hardways are not active on the come-out roll unless called on and acknowledged, and the layout uses an indicator to show that status. Other jurisdictions and casinos may approve different procedures.
The practical rule is simple: ask before the roll and listen for the dealer’s confirmation. An unconfirmed “working” call is a poor basis for a payout dispute.
Why the payout attracts attention
Hardways combine three features that make a wager memorable:
- a specific visual result—a matching pair;
- a relatively large single-win payout;
- enough non-deciding rolls to create anticipation.
That combination can make wins feel more significant than the losing decisions around them. A $5 hard 6 win produces $45 profit, while several $5 losses are individually less memorable. The average is determined by all completed bets, not by the most dramatic result.
Pressing after a win increases money exposed to the same edge. The prior profit does not improve the next hardway’s probability. A player who chooses the bet for entertainment should decide the amount and press rule before the dice roll rather than improvising after a payout.
The useful decision
Among the four hardways, hard 6 and hard 8 are mathematically less costly than hard 4 and hard 10, but none is a low-edge craps wager. The exact ranking is:
- hard 6 and hard 8: 9.09%;
- hard 4 and hard 10: 11.11%.
The difference comes entirely from the number of easy-way combinations and the payout offered against the true odds. For the wider table, compare Craps House Edge and the individual pages for Hard 4, Hard 6, Hard 8, and Hard 10.
A hardway can be a deliberate entertainment bet. It should not be mistaken for a way to improve the underlying craps mathematics. The pair is hard to roll; the payout is still one unit short of fair odds.
