While generally low-risk, 'Stack On!' can be mildly addictive due to its high-score chasing mechanic and infinite play loop. There's a minor risk of competitive toxicity or social comparison if high scores are shared among peers, and it targets children, which warrants parental awareness.

  • 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. Likely violations: monetisation that deliberately targets children.
  • 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. Likely violations: profiling or targeting of children for marketing.
  • 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 Stack On! safe for kids?

Ludograph gives Stack On! a rating of 53/100. It delivers genuine benefits but carries design risks that deserve a close look.

How long should kids play Stack On!?

Our session recommendation for Stack On! 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.

What are the main risks of Stack On!?

While generally low-risk, 'Stack On!' can be mildly addictive due to its high-score chasing mechanic and infinite play loop. There's a minor risk of competitive toxicity or social comparison if high scores are shared among peers, and it targets children, which warrants parental awareness.
