What age is Junk Jack appropriate for?

Ludograph's rubric recommends a minimum age of 7+ for Junk Jack, based on benefits, risks, and content review.

How long should kids play Junk Jack?

Our session recommendation for Junk Jack 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.
