Which Rust wheel do you mean?
The in-game Bandit Town Scrap wheel is not the Bandit.Camp gambling website. Facepunch’s original Bandit Town announcement describes numbered bets of 1, 3, 5, 10 and 20, with the stake returned in addition to the numbered payout. That is a historical settlement example, not verification of today’s weights, server configuration or any third-party skin site’s probabilities.
Use the calculator with the rules of the exact game you are checking. This guide does not establish a current official 25-segment paytable, and the examples below must not be substituted for one. A winning pattern or payout guarantee cannot be derived from this worksheet.

Check the complete payout table
Enter every mutually exclusive outcome of one wager. Each segment is assumed equally likely. A zero payout means a losing outcome.
| Segments | Probability | Return including stake | Contribution to return |
|---|---|---|---|
| 6 | 60% | 0× | 0% |
| 2 | 20% | 1.5× | 30% |
| 1 | 10% | 2× | 20% |
| 1 | 10% | 4× | 40% |

The complete-table example uses ten equal segments: six return nothing, two return 1.5×, one returns 2×, and one returns 4× including the stake. Its expected return is 90%, or an expected net loss of 10 units per 100 wagered. These are illustrative inputs, not any operator’s current wheel. If the rules use unequal probabilities, bonus rounds, refunds or overlapping outcomes, this equal-segment model is not sufficient. The export records the payout convention so the calculation can be reproduced.
Update, 5 September 2026: added complete-table validation, stake-return conventions and matching CSV/JSON exports. Operator evidence dates have not been changed by this calculator update.
Equal segments: the simple model
For a wheel with N equally likely segments, a payout appearing on c segments has probability c / N. If the same multiplier appears in several places, add all those segments. Position on the artwork does not create a separate probability when the rules define uniform selection.
A 20-segment wheel with four segments marked 2× therefore gives 4 / 20 = 20% probability of that displayed payout. The complement—landing on any other segment—is 80%. That says nothing about the whole paytable until every other outcome is counted.
Payout-completeness table
This ten-segment example is deliberately constructed for arithmetic practice. It is not copied from a live wheel.
| Total multiplier | Segment count | Probability | Contribution to expected return |
|---|---|---|---|
| 0× | 6 | 60% | 0.00 |
| 1.5× | 2 | 20% | 0.30 |
| 2× | 1 | 10% | 0.20 |
| 5× | 1 | 10% | 0.50 |
| Total | 10 | 100% | 1.00 (100%) |
Expected return is the sum of probability × total multiplier for every row. The example totals 100%, so it has no edge under its simplified definitions. Change the 5× segment to 4× and the total becomes 90%, implying a 10% edge if there are no other awards or deductions.
Be precise about whether the multiplier includes the returned stake. A “1× profit” label can mean the player also receives the stake, producing 2× total, while another interface uses 1× to mean total return. Copy the settlement wording rather than normalizing it silently.
Unequal weights and roll ranges
Artwork is insufficient when segments have different angular sizes, virtual weights or hidden roll intervals. In that model, record the complete random range allocated to each outcome. A one-pixel visual boundary cannot replace the numerical mapping.
For a roll from 0 through 9,999, a 2× region covering 2,000 integers has 20% probability. Check inclusive endpoints: 0–1,999 contains 2,000 values, while 0–2,000 contains 2,001. Reproduce the operator's exact integer or decimal convention.
Verify result generation separately
A completed-round verifier should connect the commitment and revealed inputs to the random output, then connect that output to a segment or roll range. It can reveal a correct mapping even when the paytable has a substantial edge. Conversely, a mathematically complete paytable does not show that a recorded outcome followed the stated random process.
The regulator sources describe accessible likelihood information and random generation as distinct controls. That distinction is useful beyond any one jurisdiction: keep the probability table, result method and economic settlement as separate evidence records.
Test a wheel table for silent omissions
Group identical payouts, but retain the original segment or range IDs so the sum can be traced back to the interface. Then verify three totals: probability is approximately 100%, every selectable wager has a complete settlement row, and the expected-return calculation uses total payout rather than an ambiguous profit label.
If a bonus sector triggers another wheel or award table, include that branch in the model. Treating it as a fixed prize can understate or overstate return. Progressive amounts require a timestamp and stated contribution rule; a moving jackpot cannot be inserted as a timeless constant.
Wheel audit worksheet
| Layer | What to capture | Failure condition |
|---|---|---|
| Layout | Every segment or numerical interval | A rare payout is shown but its weight is absent |
| Probability | Equal weighting rule or exact range sizes | Artwork is assumed to be probability |
| Payout | Total return for every outcome | Stake return is ambiguous |
| Expected return | Sum of all p × multiplier rows | Probabilities or payout rows are incomplete |
| Verification | Round ID, seeds, nonce, roll and mapping | A badge appears without reproducible inputs |
The game-type taxonomy explains why wheel is normally audited as a house-banked format. Use the house-edge comparison only after the full table passes the completeness check.
The Bandit Camp review links the dated public game evidence used for context; it does not support applying the example paytable to that operator.
Illustrative equal-segment wheel
| Matching segments | Nominal probability |
|---|---|
| 27 of 54 | 50.00%; fair 2x |
| 18 of 54 | 33.33%; fair 3x |
| 6 of 54 | 11.11%; fair 9x |
| 3 of 54 | 5.56%; fair 18x |
Repeatable check
- Count total and matching segments.
- Confirm equal weighting.
- Check the rule-to-result mapping.
- Compare payout with the fair multiplier.
Same segments, different payout conventions
Hypothetical example, not an operator quote.
One of ten equally likely segments wins; nine lose. If 9× includes the stake, expected return is 0.1 × 9 = 90%. If 9× means profit and the stake returns separately, expected return is 0.1 × 10 = 100%.
Check the payout convention and the complete outcome table. Visual segment size alone does not establish selection probability; previous spins do not alter an independent next spin.
