Regulatory design checks · DSA — Not yet assessed·GDPR-K — Not yet assessed·ODDS — Assessed: meets criteria

  • 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.

Ludograph gives Sayonara Umihara Kawase a rating of 63/100, recommended for ages 7 and up. It offers solid benefits but needs parental guidance on the risks.

What age is Sayonara Umihara Kawase appropriate for?

Ludograph's rubric recommends a minimum age of 7+ for Sayonara Umihara Kawase, based on benefits, risks, and content review. That is stricter than ESRB E, because our assessment weighs behavioral design risks, not just content.

How long should kids play Sayonara Umihara Kawase?

Our session recommendation for Sayonara Umihara Kawase 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.
