How it works
Dynamic systems informed by play and purchase history adjust what each player sees — offers, “frustration → sell-a-fix” difficulty, or matchmaking that surrounds them with spenders — optimised per person to increase spend, invisibly.
Why it can be harmful
Invisible, individualised targeting defeats informed consent and comparison, can exploit identified vulnerabilities (a data-protection concern), and manufactures false social proof; children and at-risk players cannot detect or resist it. The severity rating is precautionary: the harm could be severe when such targeting is deployed at scale, even though the public game-specific evidence base is still emerging.
Examples in the wild
- Behaviour-tuned in-game offers and dynamic pricing
- Game difficulty tuned to sell a fix
- Matchmaking that normalises spending
Illustrative genre examples to aid recognition — not allegations about specific titles.

Related patterns
Loot boxes / gacha
Paid, randomised reward containers whose contents — and often whose odds — are unknown before purchase.
Bad defaults / preselection
The provider-preferred option is already selected or treated as the normal path, so inaction becomes consent, spending, or data sharing.
Language inaccessibility / complex copy
Important purchase, privacy, odds, or consent information is presented in language the player cannot reasonably understand.
Trick wording / misleading copy
Confusing, ambiguous, or expectation-violating wording makes the player take an action they did not mean to take.
Fake social proof
Fabricated or unverifiable signals of others' activity — “1M players bought this!”, fake live counters — used to pressure decisions.
Premium-currency obfuscation
Real money is converted into in-game currency at non-round ratios that break the player's price intuition.
