The mine on the hill
Someone fixed a strange beacon to the post by the mine. Every lock they built has one.
Long ago, someone built clever machines into these hills: locks that answer to numbers, a wheel that drove a hoist, a power drawn from the rock itself. Then they were forgotten. Are you the one who will secretly unlock the mystery, and bring those forgotten technologies back to life?
A mystery adventure for young explorers. Roam valleys, mines and abandoned farms, follow the clues, and open every lock yourself. It plays in the browser on a laptop, tablet or phone.

A few of the places you will explore. Each one hides a lock, and every lock is a puzzle.

Someone fixed a strange beacon to the post by the mine. Every lock they built has one.

Copper-green rock on one bank, rust-red on the other, and water running between. Someone chose this ground on purpose.

A sun clock on the farm wall, its pin missing. Find the pin, and the shadow will show the way.

Knotted ropes on wooden pegs in the old barn. Count them right, and something heavy begins to move.

A farm book with its last line left empty, a radio nobody has tuned, and a round window that waits for the sun.

Something built long ago still holds a little power. What else wakes, when it does?
And over the next valley, people speak of lights in the sky: white, yellow and red. Nobody can say what they are.
Now in early testing with families.
Every lock, beacon and machine is a puzzle to crack. A small companion on your wrist has been waiting a very long time for someone to come. Find out who built all this, and why it was left behind.
