Pass line is the base bet
The simulator reserves the pass-line amount first. That amount is still at risk during the point cycle.

Craps Simulator
This browser simulator lets you practice a craps pass-line point cycle with optional odds behind the line. Enter a bankroll, pass-line bet, odds profile, table-limit reminders and session pace, then roll to see point status, active exposure, pass result, odds result, available bankroll and expected-loss context. It does not prove a betting system, certify casino dice, model every craps bet, decide state legality or recommend a casino.
This page owns one job: practicing pass-line craps rounds with honest odds exposure and bankroll handling.
Use it to understand come-out wins and losses, point establishment, odds reservation, point-made payouts, seven-out loss and how odds change active exposure. Do not use it as a full craps strategy engine, live casino RNG proof, proposition-bet calculator, legal-status answer, recovery-loss system or operator recommendation.
What this simulator does and does not do
Disclosure: this simulator uses visible craps math for pass-line and odds practice. It does not turn practice results into a prediction, betting system, casino certification, legal decision or operator recommendation.
Privacy: this tool runs in your browser. Do not enter account IDs, ticket numbers, login details, addresses, document numbers, card numbers, bank details, casino account data or private support information.
Responsible-play boundary: if a roll result creates urgency, chasing, repeated deposits or pressure to raise odds exposure, stop before opening another tool. Call or text 1-800-MY-RESET for confidential support.
This is a browser practice simulator, not a casino outcome model
This tool owns the pass-line point cycle and reserved odds exposure for practice. It does not model every craps bet, table limits, casino procedures, dice control, live dealer behavior, or state/operator approval.
The dice roll uses browser pseudorandom output for educational practice. It is not a casino RNG certification and not evidence that a betting system works.
Run the simulator
This page does not simulate proposition bets, betting systems, or live-dealer speed. It uses browser-based pseudo-random dice rolls for practice only.
Clear entered values resets this browser form and current simulated round. It does not delete TXT or CSV files you already downloaded.
How the pass line and odds work
Come-out roll
A come-out 7 or 11 wins the pass line. A 2, 3, or 12 loses the pass line. Any other total becomes the point.
Odds are reserved when the point appears
If a point is established and odds are selected, the simulator immediately reserves the pass line stake plus the odds stake so the available bankroll stops overstating free funds.
Odds payouts
Odds behind the pass line pay true odds: 4 or 10 pays 2:1, 5 or 9 pays 3:2, and 6 or 8 pays 6:5.
Seven-out
If the shooter rolls 7 before the point repeats, both the pass line stake and the reserved odds stake are lost.
Two-dice distribution
| Total | Combinations | Why it matters |
|---|---|---|
| 7 | 6 | Most common total; it wins on the come-out and loses after a point is established. |
| 6 or 8 | 5 each | These are the most common point numbers and matter when odds exposure stays live. |
| 2 or 12 | 1 each | Least common totals; they matter on the come-out because pass line loses instantly there. |
Odds payout table
| Point | True odds payout | Why it matters |
|---|---|---|
| 4 or 10 | 2 to 1 | The least common point pair among standard pass-line numbers, so true odds pay the most. |
| 5 or 9 | 3 to 2 | Middle-frequency point numbers with a lower true-odds payout than 4 or 10. |
| 6 or 8 | 6 to 5 | These points appear most often, so the true-odds payout is the smallest of the three groups. |
Pass-line point cycle
- Come-out roll decides an instant win, instant loss, or sets the point.
- If a point is set, the simulator reserves pass line and optional odds exposure immediately.
- If the point repeats, pass line and odds pay according to the point number.
- If 7 appears first, the round loses and the reserved exposure is already accounted for.
Odds bets increase reserved exposure
Odds require more bankroll
Taking odds increases the amount reserved behind the point. The payout may be true odds, but the exposure is larger.
Exposure is not safety
More reserved money can make a session swing faster. Use bankroll boundaries before increasing odds multiples.
What this craps simulator can and cannot do
Can simulate pass-line practice
Use it for come-out results, point cycles, point-made wins, seven-out losses and odds exposure behind the pass line.
Can show reserved exposure
Use active exposure and available bankroll labels to see how odds change the money at risk while a point is live.
Can support table-rule checks
Use the checklist to save table minimum, maximum, odds cap, payout chart and special-rule visibility before comparing live table claims.
Cannot model every craps bet
Field, hardways, horn, place, buy, lay, don't-pass, come bets and full-table strategy belong to other owner pages.
Cannot certify randomness
Browser pseudo-random rolls are for educational practice, not live casino RNG proof or dice-control evidence.
Cannot make gambling safer
No simulator result should be used to justify chasing, raising stakes, extending a session or depositing again.
Before using practice results outside the simulator
- Confirm live table minimums, odds multiple, and allowed bet types.
- Set bankroll, unit size, session stop point, and maximum odds exposure before play.
- Do not treat a simulated win as proof of a system.
- Do not use this page for proposition bets, hardways, come bets, lay bets, or full-table strategy.
- Use responsible-gambling support if repeated rolls become a reason to chase losses or raise exposure.
Worked examples
Come-out win
$10 on the pass line, come-out 7: the simulator returns the stake plus the win and increases available bankroll by $10.
Point with 2x odds
If the point becomes 6 and odds are set to 2x, the simulator reserves $10 on the line and $20 in odds until the point resolves or the shooter sevens out.
Seven-out loss
If the point is live and a 7 appears first, the reserved pass line and odds exposure are both lost and the available bankroll stays at the already-reserved level.
Table profile preset cards
These presets change only the inputs on this page. They are not live table claims. Verify the actual table minimum, maximum, odds cap, payout chart and bubble/electronic rules before play.
Session exposure and hourly cost estimate
This is expectation math, not a prediction.
The simulator estimates pass-line expected loss from the base pass bet only. Odds behind the pass line can pay true odds, but they increase active reserve and session swings. Roll pace is converted with an educational average of about 3.38 rolls per pass-line decision.

Craps myths and misuse checks
| Claim | Why it can mislead | Safer route |
|---|---|---|
| Odds have zero house edge | True-odds payout does not make the whole session safe; it increases reserved exposure and variance. | Use Bankroll Planner |
| Martingale beats craps | Progressions collide with table limits, bankroll exhaustion and loss-recovery pressure. | Use Reality Check Tool |
| A hot shooter is a signal | Past rolls do not make the next roll due or safer. | Treat it as entertainment, not evidence. |
| More odds always means better play | The pass-line edge is unchanged, but active reserve and swing size grow. | Set odds caps before play. |
Formula and rule snapshot
| Source or method | Used for | What it does not prove | Safest use on this page |
|---|---|---|---|
| Internal pass-line practice model v2.2 | Come-out 7/11 wins, 2/3/12 loses, 4/5/6/8/9/10 point establishment, point-made result, seven-out result, active exposure and bankroll updates. | It does not prove live casino outcomes, true-random generation, dice control, strategy success, state legality or operator approval. | Use for educational pass-line practice and bankroll exposure labels. |
| Pass-line odds payout table | Odds payouts of 2 to 1 on 4/10, 3 to 2 on 5/9 and 6 to 5 on 6/8 after a point is established. | True-odds payouts do not make the whole session safe, remove the pass-line edge or reduce the dollars at risk. | Use to understand why odds can be fair while still increasing reserved exposure. |
| Craps payout calculator | Separate owner route for common craps bet payout, true odds, house edge and EV per $100. | This pass-line simulator should not become the all-bets calculator. | Use only after the user needs payout math outside pass line plus odds practice. |
| Craps probability table | Crawlable reference for dice combinations, true odds, probability and expected-loss comparison. | A reference table does not simulate bankroll state, reserved odds or a live table session. | Use when the user needs static probability instead of practice rolls. |
| NCPG help route | Support when practice results create chasing, loss-recovery pressure or urge to raise odds exposure. | It does not verify bets, tables, payouts, casinos or simulator results. | Use before another roll, larger odds multiple or another deposit when pressure appears. |
What most craps simulators miss
Odds are fair, but exposure is larger
Taking odds can pay true odds, but the simulator still reserves more bankroll while the point is live.
Available bankroll matters before the point resolves
This page separates active exposure from available bankroll instead of pretending reserved odds are still free to use.
Practice results are not a system proof
A winning streak inside the browser does not prove dice control, Martingale, trend reading or a safer live-table session.
Craps simulator examples and edge cases
Model reviewed: June 15, 2026. These examples show visible pass-line practice boundaries. They are not public fixtures, casino certification, betting-system proof or live table predictions.
| Case | Input summary | Expected output | Boundary |
|---|---|---|---|
| Come-out 7 | $100 bankroll, $10 pass line, roll 7 | $110 available bankroll; pass-line win | Practice result only; not a prediction. |
| Come-out craps | $100 bankroll, $10 pass line, roll 2, 3 or 12 | $90 available bankroll; pass-line loss | No recovery-loss recommendation. |
| Point with odds reserved | $100 bankroll, $10 pass line, 2x odds, point 6 | $30 active exposure and $70 available bankroll | Odds increase reserved exposure. |
| Point made | Point 6 with $20 odds reserved, then roll 6 | Pass-line win plus $24 odds win; bankroll updates after the point resolves | Payout assumes standard odds math, not table-specific rounding. |
| Seven-out | Point is live with pass-line and odds exposure, then roll 7 | Pass-line and odds exposure are both lost | Do not use loss as a reason to chase. |
| Insufficient bankroll for selected odds | Selected odds profile would exceed available bankroll after a point | Validation warning before reserving impossible exposure | Simulator protects practice accounting, not live table approval. |
| 3-4-5x odds profile | $10 pass line, point 6, 3-4-5x odds | $50 odds reserved and $60 max active reserve | Odds cap depends on table rules. |
| Session exposure estimate | $10 pass line, 100 rolls/hour, 1 hour | Estimated pass-line decisions and expected-loss context | Estimate is not a session prediction. |

Craps simulator FAQ
Is this craps simulator a full craps strategy tool?
No. It focuses on pass-line come-out rolls, point cycles, optional odds exposure and bankroll handling. It does not simulate every craps bet or recommend a strategy.
Do odds bets remove the house edge?
Odds bets can pay true odds, but the pass-line bet still has its own edge and odds increase the amount reserved while the point is live. This simulator shows the exposure separately.
What does active exposure mean?
Active exposure is the money currently at risk in the round, including the pass-line bet and any odds reserved behind the point.
Can this simulator predict a real craps table?
No. The rolls are browser-based pseudo-random practice outputs. They are not a prediction, casino RNG certification, dice-control proof or table approval.
Why does the simulator reserve odds immediately after the point?
When odds are selected, the simulator reserves them after a point is established so available bankroll does not overstate money that is still free to use.
Does this simulator include hardways, field bets or horn bets?
No. Those bets belong to a broader craps payout calculator or rules guide. This page stays focused on pass line plus odds practice.
What should I check before using practice results at a live table?
Check the table minimum, maximum, odds cap, payout chart, special rules and whether the game is live, bubble, electronic or online.
When should I stop using the simulator?
Stop if the result creates urgency, chasing, pressure to raise odds, repeated deposits or a plan to recover losses. Use responsible-gambling support before another roll or another tool.
Use another page only after the pass-line practice question is finished
| If the issue is now... | Use this route | Use it only when... |
|---|---|---|
| Payout math for other craps bets | Craps payout calculator | The user needs pass, don't pass, come, odds, place, buy, lay, field, hardways or proposition payout math. |
| Static dice probability or house-edge reference | Craps probability table | The user needs combinations, probability, true odds, house edge or expected-loss comparison without running a simulator. |
| Full table layout or rules beyond pass line | Craps rules | The user needs full game rules, table layout, bet families or terms beyond pass line plus odds. |
| House edge, volatility, pace or session-risk vocabulary | Game risk terms | The user needs definitions, not another simulated roll. |
| Unit size, stop point or odds-exposure limit | Bankroll Planner | The user needs an exposure rule before increasing odds multiple or session length. |
| Chasing, urgency or pressure to keep rolling | Reality Check Tool | Practice results create pressure to chase, increase odds, extend session or deposit again. |
| KYC, payment rails, account records or support behavior | Withdrawal verification | The issue is account evidence or payout support, not craps simulation. |
| State legality or casino availability | State guides | The question is legal status, location or operator availability, not pass-line practice math. |
