Design Risk Score
Estimated34/100
4 mechanics flagged
Why this score
- Gacha System+15
Randomised paid pulls — gambling-like mechanics, cosmetic outcomes.
Why this counts
Gacha mechanics share structural features with slot machines: variable-ratio reinforcement schedules, which behavioral psychology identifies as the most powerful driver of repeated behavior. Multiple national gambling regulators have investigated or restricted these mechanics.

- Zendle & Cairns, PLOS ONE — loot boxes linked to problem gambling (2018)
- Loot Boxes+12
Randomised paid containers — gambling-like mechanics, cosmetic outcomes.
Why this counts
Loot boxes have been regulated or banned in Belgium and the Netherlands as gambling products. Research has found correlations between loot box spending and problem gambling symptom severity (Zendle & Cairns, 2018).
