- 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.
