  • 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.: Estimated from review data. No dark pattern or child-targeting concerns found.
  • GDPR-K:What Ludograph checks: whether age assurance and consent flows are designed for under-16s, in the spirit of GDPR Article 8.: Estimated from review data. No privacy or child-targeting concerns found.
  • 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.

Parents ask…

Is Grey Plague safe for kids?

Ludograph gives Grey Plague a rating of 61/100, recommended for ages 7 and up. It offers solid benefits but needs parental guidance on the risks.

What age is Grey Plague appropriate for?

Ludograph's rubric recommends a minimum age of 7+ for Grey Plague, based on benefits, risks, and content review.

How long should kids play Grey Plague?

Our session recommendation for Grey Plague 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 Grey Plague?

The game presents minimal risks, primarily a mild level of fear or unease associated with a disease outbreak and visual representations of internal organs, which may not be suitable for very young or sensitive players. It avoids manipulative design, monetization pressures, and social risks.
