The game utilizes common mobile game mechanics like variable rewards and daily incentives that can encourage prolonged play. In-app purchases for pearls and coins, combined with social comparison features, may pressure players towards spending and continuous engagement. While offering social interaction, the game's design could lead to a sense of obligation to play and keep up with friends.

Regulatory design checks · DSA — Assessed: concerns noted·GDPR-K — Assessed: concerns noted·ODDS — Assessed: meets criteria
- 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; virtual currency that obscures real-money prices; frequent spending prompts in a children-rated game.
- 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.
