The archived implementation supplies complete answer-validation behaviour, but it does not define a SIMCC tournament format.
Round length, number of cards, difficulty mix, hint or reveal penalties, and tie-breaks are not specified. The platform must not invent them before an event is configured.
The validator accepts any correct expression, while each generated card stores one known solution. The current solo mode does not award additional credit for finding alternatives.
Hard cards use exact reduced fractions with denominators up to 12. No source establishes whether an official competition would allow the full generated range.
