While generally low-risk, the game's global leaderboards could introduce mild social comparison and competitive toxicity. The 'world statistics' feature also implies some data collection, posing a minor privacy risk.

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.

Parents ask…

Is Zoo Lines safe for kids?

Ludograph gives Zoo Lines a rating of 51/100. It delivers genuine benefits but carries design risks that deserve a close look.

How long should kids play Zoo Lines?

Our session recommendation for Zoo Lines is up to 90 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 Zoo Lines?

While generally low-risk, the game's global leaderboards could introduce mild social comparison and competitive toxicity. The 'world statistics' feature also implies some data collection, posing a minor privacy risk.
