Night Shift is about messages other people send. It drills one habit: judge a message by what it asks you to do, not by whether it looks scary. Several "safe" messages deliberately contain alarming words so that blocking on vibes alone loses points.

Breadcrumbs is about what a child publishes themselves. They play the stranger first, assembling a real-world picture out of six ordinary posts, and only then go back and fix it. Deleting everything is scored as a loss, because "post nothing" is advice no child follows.

Vault is about the account itself. A child builds passwords from parts and watches a cracking machine attack them, so the lesson arrives as a number rather than a rule: four random words hold for a thousand years, while a dictionary word with a digit and a symbol on the end falls in under a second. The cracker is deliberately seeded with the facts leaked in Breadcrumbs, the pet, the street, the birthday , so "unusual to me" and "hard to guess" come apart. It ends on password reuse, which is the failure most adults have too.

Between them the games cover nine common tricks, the footprint problem and account security. Two things are treated as different in kind from the rest, and it is worth knowing why:

• Secrecy, anyone asking a child to hide a conversation from you.
• Moving somewhere private, a push into DMs, another app, photos or camera.

For those two, the game will not let a child "win" by blocking and moving on. It makes them press a second button to fetch an adult, because handling it alone is the wrong lesson. The single most useful thing you can say afterwards is that they will never be in trouble for showing you something. Children stay quiet because they expect to lose the tablet, not because they didn't spot it.
