  • 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.
  • 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 Cards of Terra safe for kids?

Ludograph gives Cards of Terra a rating of 58/100, recommended for ages 7 and up. It offers solid benefits but needs parental guidance on the risks.

What age is Cards of Terra appropriate for?

Ludograph's rubric recommends a minimum age of 7+ for Cards of Terra, based on benefits, risks, and content review. That is more lenient than ESRB E10+: industry ratings reflect content intensity, while ours also weighs how the game is designed to be played.

How long should kids play Cards of Terra?

Our session recommendation for Cards of Terra 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 Cards of Terra?

There is a slight risk of variable rewards and near-miss mechanics common in card games, and an Endless mode could encourage extended play.
