Craps myths begin with real events: a shooter rolls for half an hour, a hard 8 hits twice, a progression recovers a loss, or the table goes many rolls without a 7. The error comes afterward, when a memorable streak is treated as evidence that the probability changed.
Two fair six-sided dice have 36 equally likely ordered combinations. The casino pays less than true odds on most wagers. Neither crowd energy nor the sequence on the display changes those two facts.
Myth 1: “Seven is due”
Seven has six combinations:
1-6, 2-5, 3-4, 4-3, 5-2, 6-1
So, before any valid independent roll:
P(7) = 6 / 36 = 1 / 6 = 16.67%
If seven has not appeared for 12 rolls, the next roll still starts with the same six winning combinations for seven. The previous results explain the past; they do not remove faces from the dice.
The opposite myth is equally wrong: after two sevens, seven is not “used up.” Repetition feels unusual, but independence permits repeats.
Myth 2: a hot shooter makes place bets safer
A shooter can produce a long hand. That description is valid after the rolls occur. It does not establish that the shooter had a different probability before the next roll.
Suppose the point is on and a player has a Place 6 bet. Five combinations make 6; six combinations make 7. Ignoring other totals, the bet resolves with:
- probability of winning before 7:
5 / 11; - probability of losing to 7 first:
6 / 11.
A long hand can contain many place-bet wins, but the next resolution is not made safer by applause, previous points, or the shooter’s recent record. The Hot Shooter Myth page focuses specifically on that belief.
Myth 3: pressing with winnings beats the edge
Pressing changes the amount at risk. It does not change the payout table.
Imagine a $12 Place 6 that pays $14. If it wins and the player presses to $24, the larger wager still receives the same 7-to-6 payoff and faces the same 1.52% house edge. A winning sequence grows faster, but a seven removes a larger bet.
Progressions change the distribution of session outcomes:
- aggressive positive progressions create fewer but larger peak wins;
- loss progressions create many small recoveries and occasional severe drawdowns;
- neither changes the expected value per dollar wagered.
If a wager has a 5% house edge, every additional $100 cycled through that wager adds $5 of expected loss, regardless of whether the stake came from the original bankroll or an earlier win.
Myth 4: free odds make the whole game a zero-edge game
Pass Line and Come odds are paid at true odds. That part of the wager has no mathematical house edge. The required line or Come bet still does.
For a $10 Pass Line bet with $20 odds:
- expected loss on the $10 line bet is approximately
$10 × 1.414% = $0.1414per resolved line decision; - expected loss on the $20 odds bet is
$0; - total cash at risk when the point is active is $30;
- the expected loss remains about 14 cents, while the size of possible wins and losses increases.
Expressed against the combined $30, the average edge is lower—about 0.47% in this simplified comparison—but the player has not removed the house edge from the underlying wager. Odds improve the price of the combined action; they also require more bankroll and produce wider swings.
Myth 5: the Field is almost an even-money bet
The Field wins on many totals, which makes it feel broad. Combination counts matter more than the number of printed totals.
On a common Field layout, 2 and 12 pay 2 to 1 while 3, 4, 9, 10, and 11 pay even money. There are 16 winning combinations and 20 losing combinations.
For a $1 wager:
- ordinary wins: 14 combinations × $1;
- double wins: 2 combinations × $2;
- losses: 20 combinations × $1.
Expected value
[(14 × $1) + (2 × $2) - (20 × $1)] / 36 = -$2 / 36
That is a 5.56% house edge. If one of the extreme totals pays 3 to 1, the edge can improve, but the exact table rule must be read. “Many ways to win” does not mean the paytable is close to fair.
Myth 6: hardways are strong because the payout looks large
A Hard 8 wins only with 4-4. It loses if an easy 8 appears or if 7 appears first.
Relevant combinations are:
- one hard 8 combination;
- four easy 8 combinations;
- six seven combinations.
That gives 11 resolving combinations. A common 9-to-1 payout produces:
[(1 × $9) - (10 × $1)] / 11 = -$1 / 11
The house edge is 9.09%. The large payout is compensation for a low hit rate, and not enough compensation to match the true odds.
Hard 4 and Hard 10 commonly pay 7 to 1 and carry an 11.11% edge. These are not one-roll bets, but they are still expensive repeated action.
Myth 7: Don’t Pass is unlucky rather than differently priced
Table culture often treats Don’t Pass as betting against the shooter. Mathematics does not recognize table loyalty.
Under the common rule where 12 pushes on the come-out roll:
- Pass Line house edge is about 1.41%;
- Don’t Pass house edge is about 1.36%.
The difference is small, but it is real. A player may still prefer Pass Line for social reasons or simpler participation. That preference should not be presented as a probability claim. The dedicated Don’t Pass definition explains the two-stage wager.
Myth 8: a betting system can wait out the house edge
A Martingale, cancellation system, regression, or “same bet until it hits” plan changes the order and size of wagers. It cannot make a losing paytable fair.
Expected loss can be written as:
Expected loss = total action × house edge
If a progression creates $2,500 of action on a 5.56% Field bet:
$2,500 × 0.0556 ≈ $139
The player may win the session. Expected loss is not a session forecast. It is the average cost that emerges over repeated comparable action. Progressions often make the short-term pattern feel controlled while increasing the amount exposed to the same edge.
Myth 9: low house edge means low risk
House edge measures average cost per unit wagered. It does not describe how far a session can swing.
A low-edge line-and-odds strategy can still lose several decisions quickly because the odds portion is large and volatile. A player wagering $10 on Pass Line with $50 odds can lose $60 on one point cycle. The fair odds bet lowers the combined edge but does not protect the bankroll from short-term loss.
This is the distinction between house edge and variance. One measures average price; the other helps describe dispersion around that average.
Myth 10: every unusual result suggests bad dice
Long streaks, repeated totals, and clusters are expected somewhere in a large number of rolls. An unusual sequence is not by itself evidence of loaded dice or manipulation.
Casinos still use strict procedures because game integrity matters. Approved rules specify valid dice, handling, wagers, and settlement. The Massachusetts craps rules, for example, define the permitted Pass, Don’t Pass, Come, place, and hardway wagers and their resolution conditions. Procedure is how the game is controlled; probability is how outcomes are priced.
A genuine concern should be based on observable procedure or equipment issues and raised with casino management or the regulator—not inferred from a streak alone.
A fast way to test a craps claim
When someone presents a “system,” ask four questions:
- Which exact bet is being made?
- How many dice combinations win, lose, or push?
- What is the net payout, not just the total return?
- Does the method change those combinations or payouts?
If the answer to the fourth question is no, the method has not changed the wager’s expected value. It may change volatility, bankroll demands, or the chance of reaching a particular stop point, but not the underlying price.
Craps myths survive because short sessions produce convincing stories. The correct response is not to deny that streaks happen. It is to stop treating a streak as a new law of dice.
The social noise around the table can hide how fixed the wager structure really is. Why Craps Looks Chaotic but Is Math-Driven connects the floor experience to the probability underneath it.
