  • 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 Im Not Number safe for kids?

Ludograph gives Im Not Number a rating of 33/100. There are notable risks worth knowing before letting kids play.

How long should kids play Im Not Number?

Our session recommendation for Im Not Number 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.
