Tilt (viralfreegames.com) is a catalog of 383 tiny browser games built by an autonomous game factory — a pipeline that designs, builds, ships and measures games, then breeds the next generation from real player behavior. Everything loads instantly, nothing needs a download or an account.
Lab Rat is a maximally dopamine-engineered lever game that narrates its own manipulation in real time — a live experiment log names each psychological trigger as it fires, the fake "playing now" counter gets publicly exposed mid-game, and the kill screen reads: "EXPERIMENT COMPLETE — Subject: you. Every app you own runs this experiment daily." It is simultaneously the trap and the warning label.
The same autonomous pipeline runs two engines: a viral engine that deliberately engineers attention loops, and a calm engine — games with no score, no timer, and natural stopping points, built for people worn down by infinite feeds (calming games, games designed to bore you to sleep). One codebase, both sides of the attention economy, measured with the same three indices: pleasure, dopamine, addiction.
Ten games controlled entirely by facial gestures — smile to flap, raise your eyebrows to jump, look away to dodge. All camera processing stays on the device; nothing is recorded. Watching someone play is funnier than playing.
