How it works
Purchases are denominated in gems/coins sold in bundles that never quite match item prices, leaving stranded balances and obscuring the real cost of any single item.
Why it can be harmful
The extra conversion step severs the felt link between money and goods, so players systematically under-perceive what they are spending — especially harmful for children and when combined with randomised rewards.
Examples in the wild
- Buying 1,000 gems for a 1,200-gem item, forcing another purchase
- Multiple stacked currencies (coins, gems, tickets)
Illustrative genre examples to aid recognition — not allegations about specific titles.

Loot boxes / gacha
Paid, randomised reward containers whose contents — and often whose odds — are unknown before purchase.
Disguised ads / content
Ads are styled as gameplay or rewards so the player cannot tell promotion from play.
Personalised spend-optimisation
Silently using a player's behavioural data to tune offers, prices, odds, difficulty, or matchmaking to maximise that individual's spending.
Accidental-purchase / default-to-purchase UI
Purchase is the default or easily mis-tapped path, so spending happens without express, informed consent.
Predatory / forced advertising
Unskippable or rewarded ads — sometimes disguised as content — are bundled into progression.
Hidden / undisclosed odds
The probability of outcomes in a paid randomised reward is withheld, buried, or hard to verify.
