Craps Hardway Calculator: Betting on Doubles

Hardway bets wager that a number will roll as doubles before it rolls "easy" or before a 7. Our calculator shows the exact probability, payouts, and house edge for hard 4, 6, 8, and 10—revealing why these exciting bets are mathematically poor choices.

What Is a Hardway Bet?

A hardway bet wins when a number rolls as doubles (2-2, 3-3, 4-4, or 5-5) before rolling any other combination that totals that number or before a 7. Hard 6 (3-3) must appear before easy 6 (4-2, 5-1) or 7.

Quick Answer: Hardways are multi-roll bets on doubles. Hard 4 (2-2) and Hard 10 (5-5): pay 7:1, house edge 11.11%. Hard 6 (3-3) and Hard 8 (4-4): pay 9:1, house edge 9.09%. Stay active until won, lost to easy way, or lost to 7. Among worse craps bets but not the absolute worst.

Multi-Roll Dynamics

How Long Do Hardways Last?

Hard 4/10:
Decision every: 9/36 = 25% of rolls
Average rolls to resolution: 4

Hard 6/8:
Decision every: 11/36 = 30.6% of rolls
Average rolls to resolution: ~3.3

Hardways resolve relatively quickly
Not like place bets that continue

Come-Out Roll Behavior

Default: Hardways "off" on come-out
7 or 11 doesn't affect hardways

Can request "working":
Then 7 on come-out loses hardways

Most players leave them off
To protect during come-out

Hardways vs Other Craps Bets

House Edge Comparison

Best craps bets:
Pass/Don't Pass: 1.41%/1.36%
Come/Don't Come: 1.41%/1.36%
Place 6/8: 1.52%

Hardways:
Hard 6/8: 9.09%
Hard 4/10: 11.11%

Worse craps bets:
Any 7: 16.67%
Big 6/8: 9.09%

Why Players Make Hardways

Psychology:
- Exciting to root for doubles
- Higher payouts than place bets
- Multi-roll adds anticipation

Reality:
- 6-7× higher edge than pass line
- Most of the time you lose
- Entertainment, not strategy

Real-World Examples

Example 1: Hard 8 Session

Bet: $5 on hard 8, 20 resolutions

Expected results:

Wins: ~2 (9.09% × 20 = 1.8)
Losses: ~18

Wins: 2 × $45 = $90
Losses: 18 × $5 = $90

Break even? Just variance
Long-term: lose 9.09%

Example 2: All Hardways Working

Bet: $5 each on hard 4, 6, 8, 10 ($20 total)

Per roll:

Most rolls: No hardway decision
Some rolls: Hit or lose one bet

Hard 4 hit: +$35, others continue
Easy 8 rolls: -$5 on hard 8, others continue
7 rolls: -$20 (all hardways lose)

7 is the killer
Happens 6/36 = 16.67% of rolls

Example 3: Parlaying Hardways

Strategy: Let hardway winnings ride

Analysis:

Win hard 8: $45
Parlay to $50 on hard 8

Second hit probability: 9.09%
Both hits: 0.0909 × 0.0909 = 0.83%

99.17% of time: Eventually lose all
Exciting but mathematically poor

Example 4: Hop vs Hardway

Comparison: Hard 6 vs Hopping 3-3

Hard 6:
Multi-roll (until resolution)
9:1 payout
9.09% house edge

Hop 3-3:
Single roll only
30:1 payout
13.89% house edge

Hardway has better edge
But hop resolves immediately
Different bet structures

Strategy Considerations

When Players Use Hardways

Common situations:
- After point established
- As "hedge" with place bets
- For entertainment/tipping dealers
- When feeling lucky

None of these are strategic
All are entertainment spending

If You Must Play Hardways

Hard 6/8 slightly better: 9.09% vs 11.11%
Keep bets small: Entertainment, not investment
Turn off on come-out: Protect from 7
Don't chase: Accept losses

Common Mistakes

1. Thinking Hardways Protect Place Bets

Mistake: "If 7 hits, at least I win hard 6" Problem: 7 loses hardways too Fix: Hardways are not hedges

2. Always Working Hardways

Mistake: Keep working on come-out Problem: 7 wipes all hardways Fix: Leave off unless intentional

3. Betting All Four Hardways

Mistake: Cover all doubles Problem: 7 kills all four at once Fix: One or two at most

4. Confusing with Hop Bets

Mistake: Think hardway = one roll Problem: Hardways are multi-roll Fix: Understand bet duration

Frequently Asked Questions

Which hardway is best?

Hard 6 and 8 at 9.09% edge are slightly better than hard 4 and 10 at 11.11%. But all are poor bets.

Do hardways stay up after a decision?

No. Once won or lost, the bet resolves. You must place a new bet to continue.

Can I take down hardway bets?

Yes, anytime. Unlike place bets, you can also turn them "off" temporarily.

Are hardways working on come-out?

By default, no. You can request they work, but 7 would take them.

How does hard 4 differ from hop 2-2?

Hardway stays until resolution (multi-roll). Hop is single roll only. Different payouts and odds.

Should I tip dealers with hardways?

If you want to tip, hardways work. But dealer would receive more value from pass line tip.

Pro Tips

• Stick to 6 and 8: 9.09% beats 11.11%

• Small bets only: Entertainment cost

• Off on come-out: Default is fine

• Don't hedge: Hardways aren't protection

• Pass line instead: Much better edge
