  • DSA:What Ludograph checks: whether the game's design gives minors the transparency the EU Digital Services Act expects: plain terms, honest defaults, and clear reporting routes.
  • GDPR-K:What Ludograph checks: whether age assurance and consent flows are designed for under-16s, in the spirit of GDPR Article 8.
  • ODDS:What Ludograph checks: whether paid random-reward drop rates are disclosed, as required in China, Japan and South Korea.: Estimated from review data. No paid random-reward mechanics found, so drop-rate disclosure requirements do not apply.

These reflect Ludograph's assessment of the game's design practices against each framework's criteria, not a legal compliance determination.

What age is Simplex Mundi appropriate for?

Ludograph's rubric recommends a minimum age of 13+ for Simplex Mundi, based on benefits, risks, and content review.

How long should kids play Simplex Mundi?

Our session recommendation for Simplex Mundi is up to 120 minutes per day. It is derived from the game's own structure (natural stopping points, compulsion-loop design, monetization pressure, and social dynamics), not from a universal screen-time dose.

Session recommendations are design-based heuristics. Evidence linking specific daily durations to child outcomes is limited, and context matters as much as time; treat this as a starting point for household rules, not a clinical threshold.

What are the main risks of Simplex Mundi?

The game contains moderate violence and mild fear elements due to its combat-focused gameplay and mysterious world. The presence of microtransactions introduces a potential monetization risk, though specific manipulative mechanics are not detailed.
