A no-roll call means the dice throw does not count. It can happen when dice leave the table, are interfered with, fail to meet house throwing rules, stop in an unreadable position, or move during a dispute. A no-roll protects the integrity of the game; it is not a way to cancel an unlucky result.
Quick Facts
- No roll cancels the dice result completely.
- It is usually called by the stickman, boxman, or supervisor depending on procedure.
- Dice off table, player interference, and unclear dice positions are common causes.
- Late bets do not normally create no roll; they are usually refused.
- A shooter repeatedly failing to hit the wall may be warned or removed as shooter.
- No-roll decisions should be made before bets are paid or collected.
- The same rule should apply whether the result helped or hurt the player.
Plain Talk
Craps moves quickly, so the game needs a way to cancel a throw when the result is not clean. That cancellation is called no roll.
The important point is timing. A no-roll call should happen because of the throw or table condition, not because the result was unpopular. The Massachusetts Craps and Mini-Craps rules identify several dice-handling and no-roll situations. Equipment and dice controls such as 205 CMR gaming equipment standards explain why dice integrity matters. House edge references like the Wizard of Odds house-edge comparison assume clean resolved bets, not cancelled rolls.

How It Works
No-roll calls usually fall into categories:
| Cause | What happened | Normal casino concern |
|---|---|---|
| Dice off table | One or both dice leave the playing surface | Security and inspection |
| Interference | A hand, chip, object, or person affects dice | Clean result cannot be trusted |
| Short roll | Dice fail to travel properly or hit the wall | Throw standard not met |
| Cocked die | A die rests at an angle or unreadable position | Total is unclear |
| Wrong shooter/dice issue | Dice offered or thrown incorrectly | Procedure broken |
| Late confusion | Action or claims happen while dice move | Bet state must be protected |
A no-roll is powerful because it erases the result. That is why casinos are careful. Calling no roll too easily invites player manipulation. Refusing a proper no-roll creates disputes and weakens game protection.
Craps Table Example
A shooter throws the dice. One die hits the wall and lands 3. The other die bounces over the rail and onto the floor. The stickman calls no roll. The table result is cancelled. The dice may be inspected, replaced, or returned depending on house procedure.
Next roll, a player reaches into the layout to grab a payout while the dice are still moving. The dice hit his hand and land 6-1. The table has a real interference issue. If the crew allows that result without a ruling, the game becomes impossible to defend.
From the Casino Side:
The boxman and floor care about consistency. If a die off table is no roll when the player would have won, it should also be no roll when the player would have lost. The table cannot look selective.
Surveillance cares about sequence. Did the dice leave the shooter’s hand? Did the stickman call no roll before the crew saw the final result? Did a player interfere? Were chips or hands in the dice path? A clean call is one that can be replayed on camera without embarrassment.
Common Mistakes
- Asking for no roll only after seeing a losing number.
- Thinking every die that touches chips must be cancelled.
- Believing a late bet forces the casino to cancel the roll.
- Throwing short repeatedly and acting surprised when warned.
- Reaching into the layout after the dice are out.
- Assuming a table cheer or groan changes the ruling.
- Confusing a refused late bet with a no-roll decision.
Hard Truth
No roll is not an undo button. It is a control call for a dirty dice event.
FAQ
Who can call no roll?
It depends on house and jurisdiction, but the stickman, boxman, and floor supervisor may be involved. The box or floor often has final authority in a dispute.
Does no roll mean all bets stay up?
Yes. Since the result did not count, unresolved bets remain as they were unless the table was already in another procedural state.
Can a casino call no roll after seeing the result?
It can happen in messy situations, but good procedure calls no roll as soon as the issue is recognized. Late selective calls create disputes.
Is dice off table always no roll?
Usually, but exact procedures vary. The dice may also be inspected or replaced because off-table dice can be touched or tampered with.
Can short rolling be no roll?
Yes, especially after warnings or when the throw clearly violates house rules. Some houses first warn the shooter before stronger action.
What if the player caused the interference?
The crew still rules by procedure. The player may be warned, and repeated interference can lead to removal from the game.
Deeper Insight
No-roll calls sit between math and procedure. A dice total has mathematical meaning only if the roll is accepted. That is why no-roll decisions affect trust. Players hate them when they erase a winner. Casinos hate them when they become inconsistent or exploitable.
The strongest crew habit is to protect the dice path before the roll: clear hands, settle late action, move the dice cleanly, and call the result clearly. The fewer messy throws you allow, the fewer no-roll fights you get.
Formula / Calculation
Clean settlement chain:
Valid dice event → accepted roll → dice total → bet settlement
If the event is no roll:
Accepted roll = 0
Bet settlement = no change
Formula Explanation in Plain English
No roll stops the process before probability applies. The table does not ask whether the number was good or bad. It asks whether the roll counted at all.
