Checklist for Reviewing a Provably Fair Result Mismatch

A displayed outcome that appears inconsistent with a provably fair calculation should be approached methodically. Readers can preserve the available information, repeat the calculation and compare each input before deciding whether a mismatch exists. This checklist provides a neutral process and does not assess any operator or individual outcome.

Preserve the original information

Before refreshing a page or starting another round, readers can record every visible value associated with the outcome. Relevant details may include:

• the server seed or its displayed hash;
• the client seed;
• the nonce or round counter;
• the game identifier and round reference;
• the calculation method shown in the rules; and
• the displayed outcome.

Screenshots can help preserve context, but copied text may be easier to compare character by character. Readers should avoid sharing any value marked as private or confidential.

Compare inputs carefully

Many apparent differences can come from transcription or formatting. Readers can compare uppercase and lowercase characters, spaces, punctuation, leading zeroes and the order of the inputs. They can also check whether a seed was rotated and whether the values belong to the same round.

The relevant game rules should explain how inputs are combined and transformed. Readers can check whether the calculation uses hexadecimal or decimal values, how a hash is interpreted, and whether rounding is applied. No step should be assumed merely because another game uses a similar method.

Repeat the calculation independently

Readers can use the published formula to reproduce the calculation without altering any input. A second attempt using separately copied values may reveal a transcription error. If an independent verifier is used, its stated formula and input order should match the rules being reviewed.

For a focused overview of points to examine, see this provably fair mismatch checklist. The linked material should be treated as one reference rather than proof that a particular outcome is correct or incorrect.

Document unresolved differences

If the values still differ, readers can prepare a concise record containing the round reference, all non-sensitive inputs, the displayed calculation method, the expected output and the observed output. Each item should be labelled clearly so that another person can repeat the comparison.

Readers should also distinguish between a calculation mismatch and a display issue. A rounded visual value, an animation or a game-specific conversion step may require separate examination under the applicable rules.

Final review

Before reaching a conclusion, readers can verify that:

• every value comes from the same round;
• the correct formula and input order were used;
• formatting was preserved exactly;
• any conversion and rounding steps were applied as written; and
• the comparison can be repeated from the recorded information.

A structured review helps separate input errors, interpretation differences and genuinely unresolved discrepancies without making unsupported claims.
