Craps Any Seven Calculator: Big Red, Bigger Loss

Any seven (also called "Big Red") is tempting—seven is the most common roll. But this one-roll proposition bet carries a crushing 16.67% house edge, making it the worst standard bet on the craps table.

What Is the Any Seven Bet?

Any seven is a one-roll bet that wins if 7 appears on the next throw. Placed in the center proposition area, it pays 4:1. Sounds reasonable since 7 is the most frequent roll, but the payout shortchanges true odds dramatically.

Quick Answer: Any seven wins 16.67% of the time (6 ways out of 36). True odds: 5:1. Casino pays: 4:1. House edge: 16.67%—the highest on the standard craps layout. Betting $5 on any seven costs $0.83 in expected value every roll. Avoid this bet entirely. The pass line at 1.41% edge is 12× better.

Real-World Examples

Example 1: Single Bet Analysis

Bet: $10 on any seven

Expected outcome:

Win probability: 16.67%
Win amount: $40 (4:1)
Lose probability: 83.33%
Lose amount: $10

EV = ($40 × 0.167) - ($10 × 0.833)
EV = $6.68 - $8.33 = -$1.65

Losing $1.65 per $10 bet
16.5% of your money gone

Example 2: Session Simulation

Strategy: $5 any seven every roll for 100 rolls

Expected results:

Wins: ~17 times × $20 = $340
Losses: ~83 times × $5 = $415

Net expected: -$75 (on $500 wagered)
Actual loss rate: 15-18% variance

Example 3: Why Sevens Tempt

Shooter establishes point of 4:

Thought process:

"Seven is more likely than 4!"
(True: 6 vs 3 combinations)

"I'll bet any seven!"
Problem: Paying 4:1 instead of fair 5:1
Even being "right" loses money

Example 4: Hourly Devastation

Aggressive any seven player:

Bets: $10 any seven
Frequency: 50 times per hour
Expected loss: $10 × 50 × 16.67% = $83.35

Per 4-hour session: $333 expected loss
Compare to pass line at same volume: $28

Frequently Asked Questions

If seven is most common, why is this bet bad?

The 4:1 payout doesn't match the 5:1 true odds. Being right 16.67% of the time doesn't help when you're underpaid every win.

Are there any scenarios where any seven makes sense?

Mathematically, no. Some say as a "desperation hedge" on large place bets, but even then, the math is negative.

How does any seven compare to lottery?

Lottery typically has 50% house edge. Any seven at 16.67% is better than lottery but far worse than any table game.

Do dealers push any seven bets?

Some dealers encourage proposition bets for tips. Don't fall for it. They make their money regardless of your wins.

Why do casinos even offer this bet?

Profit. 16.67% return is exceptional for the house. It preys on misunderstanding of probability.

What should I bet instead?

Pass or don't pass (1.36-1.41% edge), come bets, or place 6/8 (1.52%). Anything with odds is dramatically better.

• Understand true odds: 5:1 vs 4:1 creates massive edge

• Avoid center bets generally: All propositions carry high edges

• Stick to pass/come with odds: Best bets on the table
