Design risks
| R1 | Compulsion-loop pressure | 0.43 | |
| R2 | Monetization | 0.13 | |
| R3 | Social risk | 0.00 | |
Despite being free of direct monetization (microtransactions, subscriptions), the game's 'addictive' design and likely reliance on advertising present risks. The absence of natural stopping points, combined with potential compulsion-loop design mechanics like variable rewards and near-misses, could lead to excessive screen time. The constant ad interruptions, if present, could also detract from the experience and potentially expose players to inappropriate content.

- 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.
