  • 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 Idle Duels safe for kids?

Ludograph gives Idle Duels a rating of 31/100, recommended for ages 7 and up. Significant risks make this hard to recommend for younger players.

What age is Idle Duels appropriate for?

Ludograph's rubric recommends a minimum age of 7+ for Idle Duels, 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 Idle Duels?

Our session recommendation for Idle Duels 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 Idle Duels?

The game's idle RPG design incorporates several compulsion-loop design mechanics, such as variable rewards for gear drops and an infinite play loop, which can encourage prolonged engagement. The leaderboard system may also foster social comparison.
