Blind boxes: Why mystery toys trigger gambling‑like dopamine effects in children

Blind boxes are small collectible toys sold in sealed mystery packages, such as Labubus, “dumpling squishies” and Lego minifigures. Buyers do not know which figure they will receive until the package is opened, creating a game of chance similar to lucky‑dip or Pokemon card packs.

Legal analysis shows that blind boxes do not meet the definition of gambling in jurisdictions like Australia because purchasers always receive a product and there is no opportunity to lose money. However, the uncertainty and anticipation activate dopamine pathways in the brain, the same neurochemical response that fuels gambling addiction. The dopamine surge occurs not only on winning but also when a near‑win is perceived, reinforcing repetitive purchasing behavior.

Experts advise parents to set clear limits, such as allocating a fixed amount of pocket money for blind‑box purchases or encouraging children to wait until they are home to open the packages. These strategies aim to reduce impulsive buying and help children make informed, healthier choices while still enjoying the surprise element.
