Your kids become the experts. They crack the codes, find the locations, and unlock secrets that most adults walk straight past. You just get to watch them shine.
One download. One city. One day they won't forget.
When your kids get stuck, their agents step in. Each character drops a personalised field clue — keeping spirits high, keeping the mission alive, and keeping everyone moving.
Not another museum queue. Not another audio guide nobody listened to. This is the day your kids talk about for years — because they did it themselves.
Your kids hold the dossier, read the briefings, navigate to each location, and figure out the answer themselves. You follow. You watch. You enjoy the city at their pace — which turns out to be surprisingly fast when they're motivated.
Every location is a real hidden story — history, science, art, architecture. The kind of fact that sticks because they discovered it themselves, standing in front of it, having worked to get there. No worksheet. No quiz. Just genuine discovery.
Cracking a coded password and watching confetti explode across the screen is a real moment of triumph. Getting all ten is something they'll actually boast about. The mission certificate at the end is theirs — earned, not handed to them.
The look on their face when they solve a hard one. The argument about which way to go that you all laughed about later. Standing together at a viewpoint nobody else knew was there. These are the memories that come from doing things together, not from seeing things.
Click any city on the map to get that city's hunt. Every operation is a completely different adventure — written specifically for that city's real hidden secrets.

Each hunt is built around real hidden places that most tourists — and most locals — walk straight past. Ten locations. Ten coded passwords. One unforgettable day.
A church hidden in an attic for 150 years. The world's only microbe zoo. The narrowest house in Europe. A sailors' bar that accepted live monkeys as payment.
A Cycladic island village built overnight on the Acropolis slope. The world's oldest weather station. The world's first theatre. Steam power invented 1,700 years early.
Roman columns hidden in a hiking club. A 6th-century synagogue below street level. A square where Civil War shrapnel is still in the church walls.
A throne made from narwhal tusks the craftsmen thought were unicorn horns. A time traveller's grave. An elevator that never stops. 22,000 unique beer bottles.
700-year-old mummies in a church crypt. Saint Valentine's actual remains in a golden casket. A tree eating a park bench. The last arch of Dublin's lost medieval wall.
Michelangelo's secret hiding room. Wine holes in palace walls. His graffiti carved in seconds on a palazzo. The door competition that accidentally started the Renaissance.
Where the internet was invented. A building with zero right angles. A 12-metre broken chair outside the UN. Two rivers flowing side by side that refuse to mix.
Two Victorian houses that are pure painted facade. A wall honouring forgotten heroes. A secret underground postal railway. England's smallest square behind an unmarked arch.
A skull-lined bone church, a bull buried in gold, a defiant fist in the financial district, a cathedral with 135 spires hiding centuries of secrets.
Eiffel's secret apartment where Edison visited. The alchemist's house whose tomb was found empty. 135 bronze discs tracing France's rival to Greenwich. A bookshop where writers sleep free.
The bookshop built from painted plaster not wood. 20,000 tiles telling 8 centuries of history. A Moorish palace inside a stock exchange. A fishing village frozen in 1960.
The most beautiful library nobody visits. A street 50cm wide with its own traffic lights. An elevator that never stops. A garden with free-roaming peacocks nobody finds.
A keyhole that frames three countries at once. A mouth that bites liars. A crypt of 4,000 monks' bones. The spot where Caesar was stabbed — now a cat sanctuary.
A Roman emperor's palace that became a living city for 1,700 years. 507 taxidermied frogs in human scenes. The only sport in the world played only in one city.
A devil's bridge, a cat's funeral carved in stone, a Roman racetrack buried under the streets, and a tower locals called Pontius Pilate's home for 800 years.
No app to download. No account to create. No instructions to wade through. If your kids can use a phone, they can run this mission.
Pay €9.99 via Gumroad and your personalised mission file arrives in your email within minutes. One HTML file. That's it. No app store. No account. No subscription. Ever.

Your child enters their agent codename and receives their classified dossier. They navigate, investigate, and crack ten coded passwords to unlock the city's secrets. You walk alongside and enjoy the ride.
Every solved location triggers a confetti celebration. Crack all ten and the mission complete screen goes wild. Your squad earns a mission certificate — with their agent name on it. They did it. And you were there.
"My kids refused to go to museums. They did this for six hours and didn't want to stop. I was the one suggesting we take a break. The bone crypt terrified and absolutely thrilled them."
"My daughter was the navigator, my son handled the passwords. They were a team. I just walked with them and watched. It was honestly one of the best days we've had on any holiday."
"My son stood at the Jonction for ten minutes just watching the two rivers refuse to mix. He figured out why himself. Still talks about it six months later. That's the kind of thing that stays."
