Maths Warriors — Rules Changelog
This log records published documentation versions. It does not turn an unresolved question into
a rule: only an authoritative SIMCC ruling can do that.
2026.07.31 — Shared-engine reference
Status: current implementation reference.
- Published the rulebook, tournament reference, changelog and open questions as one rendered,
searchable source.
- Recorded that the current web client and Node server consume one shared rules engine.
- Marked the archived client/server divergence table as migration history.
- Recorded that the puzzle trainer uses the same arithmetic evaluator as match play.
- Added stable clause links and a print/PDF layout.
- No ruling was made on open questions 1, 2, 8, 9 or 16.
2026.07.30 — Arithmetic documentation correction
Status: superseded by 2026.07.31.
- Corrected the timeout cross-reference to point to open question 2.
- Flagged the all-equal first-player tiebreak discrepancy as open question 9.
- Aligned puzzle evaluation with the game’s standard operator precedence.
- No tournament rule was changed.
Version policy
Each published snapshot uses a date tag in YYYY.MM.DD form. An event should record the exact
tag it uses before play starts. When SIMCC resolves an open question, the ruling must be added
here under a new tag; existing tagged text is not silently rewritten.
