How long should kids play Quern - Undying Thoughts?

Our session recommendation for Quern - Undying Thoughts 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.
