Craps Hardway Calculator: The Math Behind Doubles (2026)
Craps Hardway Calculator: Double Trouble
Hardway bets require hitting doubles before either a 7 or the "easy" way. Our calculator shows the true probability, compares it to payouts, and reveals why these exciting bets carry some of the table's steepest house edges.
What Are Hardway Bets?
A hardway bet wins when both dice show the same number to total 4, 6, 8, or 10 (2-2, 3-3, 4-4, or 5-5). It loses if a 7 rolls or if the number comes "easy" (different numbers totaling the same). These are working bets that stay up until they win or lose.
Quick Answer: Hard 6/8 pays 9:1, true odds 10:1, house edge 9.09%. Hard 4/10 pays 7:1, true odds 8:1, house edge 11.11%. Hardways are among the worst bets on the table. Hard 6 has 1 way to win (3-3), 6 ways to lose to 7, and 4 ways to lose to easy 6. That's 1 win vs 10 losses—terrible odds disguised by exciting payouts.

Real-World Examples
Example 1: Hard 6 Session
Bet: $5 on Hard 6
Over 110 rolls (10 resolutions):
Expected outcomes:
Wins: ~1 (pays $45)
Losses: ~9 (loses $45)
Theoretical:
Win 1/11 times = 0.909 wins
Lose 10/11 times = 9.09 losses
EV per $5 bet:
($45 × 1/11) - ($5 × 10/11)
= $4.09 - $4.55
= -$0.45 per resolution
House edge: 9.09%
Example 2: Hopping Hard 6 vs Working Hard 6
Hopping (one-roll bet):
$5 hop hard 6 (one roll only)
Win: $145 (29:1)
Lose: $5 on any other result
Probability: 1/36 = 2.78%
House edge: 13.89%
Working Hard 6:
$5 hard 6 (until resolution)
Win: $45 (9:1)
Lose: $5 on 7 or easy 6
Probability per resolution: 9.09%
House edge: 9.09%
Working hardway is better but still bad.
Example 3: All Hardways Strategy
Bet: $5 on each hardway ($20 total)
Analysis:
Hard 4: -$0.56 EV
Hard 6: -$0.45 EV
Hard 8: -$0.45 EV
Hard 10: -$0.56 EV
Total EV per round: -$2.02
Combined edge: 10.1% of $20 bet
Very expensive "insurance" or excitement
Example 4: Hourly Cost Comparison
40 decisions per hour, $5 bets:
Hard 6/8:
Decisions: 40
Bet: $5
EV per decision: -$0.45
Hourly loss: $18
Pass line with odds:
Come out + made point resolution: ~40/hour
Base bet: $5, odds: $10
Effective edge: 0.85%
Hourly loss: ~$1.70
Hardways cost 10× more per hour than basic strategy.
Why Players Love Hardways
The Appeal
1. High payouts (7:1, 9:1)
2. Visual excitement (matching dice)
3. Stay working through multiple rolls
4. Celebrate with dealers/players
5. "Insurance" feeling when point is a hardway number
The Reality
1. Terrible odds (9-11% edge)
2. Most outcomes lose
3. Long-term guaranteed loss
4. One of worst bets on table
5. Entertainment value only
Hardway "Systems"
Pressing Hardways
Strategy: Reinvest winnings
Win hard 6 ($45), press to $25
Problem:
You're betting $25 at 9.09% edge
Pressing doesn't change probability
Just increases variance and expected loss
Taking Down vs Leaving Up
After point made, hardways still work
Option 1: Take down (break even)
Option 2: Leave up (continue exposure)
Math says: Take down
Emotion says: Let it ride
House edge unchanged either way
Hardway "Protection"
Point is 6, bet hard 6 as "protection"
Theory: Win either way
Reality: Adding -9.09% bet to pass line
Pass line alone: 1.41% edge
With hard 6: Higher overall edge
Not protection, just more gambling

2. Pressing Winners
Mistake: Let it ride after wins Problem: Increases exposure at terrible odds Fix: Take profits, reset small
3. Chasing Hardway Points
Mistake: Point is 6, must bet hard 6 Problem: Compounding bad bets Fix: Pass/odds alone is sufficient
4. Believing in Patterns
Mistake: Hard 6 hasn't hit, it's "due" Problem: Each roll is independent Fix: Understand randomness
