Zagal, Björk, Lewis, Dark Patterns in the Design of Games. ## Variants ### Variants and applications - Constant indicators of unclaimed status: icons and counters encourage you to open sections - Ready notifications: the game reminds you when production is completed or a resource has been restored - Loss Notifications: Message encourages you to return to protect your gains. - Messages about friends' activities: someone else's activity becomes a reason for your own - Constant demonstration of future rewards: desired items remain in front of your eyes - Mandatory visit to the store for a free reward: receiving a free one is accompanied by the display of paid offers - Suggestions at the time of failure or lack of resource: a purchase is shown when it solves the problem that has arisen - Personalization of incentives by behavior: time, content of notifications and offers are adjusted to the specific player ## Context and limits A map of 160 techniques for analyzing interest, returns, costs and pressure on the player. Involvement in itself does not mean dependence; the presence of separate mechanics does not determine the diagnosis or prove causation. This is the author's classification for critical analysis of design, and not a scientifically established list of the causes of gaming disorder. Assess context, audience, voluntariness of participation, and opportunity to stop. ## Connected materials ## Sources and provenance Original editorial design catalog consolidated from project discussions on 2026-10-20.
