Roblox and Childhood Gambling Risk: Beyond the Loot Box.

The commentary by Mortillaro and colleagues1 makes a timely and well-constructed contribution to the literature on childhood gambling risk. Their framework, linking variable ratio reinforcement, dopaminergic neurocircuitry, and adolescent neurodevelopmental vulnerability to the mechanics of gacha games, provides a clinically useful foundation for understanding how digital monetization may exploit developmental susceptibility. Although Mortillaro et al. focus primarily on Genshin Impact and Raid: Shadow Legends, games with predominantly adolescent and young adult users, we write to extend this framework to Roblox.
