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 Pass Line Simulator
This tool simulates the pass line and optional odds behind it. It is a browser-based practice simulator for the point cycle, not a broad craps strategy suite, state hub, casino directory, or API surface.
This page owns one job: practicing pass line and odds resolution with honest bankroll handling.
It does not automate proposition bets, systems, side bets, live dealer timing, or commercial casino routing. When a point is live, the simulator shows reserved exposure separately from available bankroll.
Disclosure
If commercial links appear elsewhere on the site, they do not change the odds, bankroll logic, or limits shown on this page. The dice rolls here use browser-based pseudo-randomization for practice only.
Privacy note: this simulator 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. Export and share controls include assumptions only.
Responsible-play boundary: if a roll result creates urgency, chasing, repeated deposits, or pressure to raise odds exposure, stop. Call or text 1-800-MY-RESET for confidential support before opening another tool.
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.

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 simulator does not do
No proposition bets
This page does not simulate horn bets, hardways, field bets, place bets, or buy bets.
No betting systems
Martingale-style progression, scripted systems, and broad strategy engines do not live on this page.
No true-random claim
The rolls use browser-based pseudo-randomization. This is enough for practice, but it is not marketed here as true random generation.
No state or casino wrappers
The pass line math does not change because of a state card or casino card on the root page, so those shells are removed.
Bankroll exposure example
$10 pass line with 2x odds reserves $30 while the point is live.
That split between reserved exposure and available bankroll is what keeps the simulator honest. The page does not wait until the end of the round to pretend those funds were still free.
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.

At least one point hit / seven-out check
This module uses baseline pass-line decision probabilities. It shows "at least once over N decisions" context only. The next roll is still independent.

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. |

Craps simulator FAQ
Is this craps simulator a betting system?
No. It is a browser practice simulator for pass-line point-cycle math and odds exposure. It does not prove a system, dice control or future outcomes.
Does taking odds make a craps session safe?
No. Odds can pay true odds behind the pass line, but they also increase the amount reserved and at risk while the point is live.
Does this page simulate all craps bets?
No. It focuses on the pass line, point cycle and optional odds. It does not simulate field, hardways, horn, place, buy, lay, don't-pass, come bets or full table strategy.
Can I save the simulator result?
Yes. The page can copy a plain summary, download TXT or CSV output, and copy a share URL with non-private assumptions. Review exports before sharing.
When should I stop using the simulator?
Stop if the result creates pressure to chase, raise exposure, deposit again, or ignore a planned stop. Use responsible-gambling support before opening another calculator.
