How long do I have to use it?

It opens the moment the payment clears. 180 days from purchase, with no subscription behind it and nothing to cancel, so a trip that slips by a month is not a trip you pay for twice.

What if a riddle beats us?

Take a hint. They are there from the first riddle and they cost points rather than progress — the score comes out lower and the walk carries on. No puzzle can end the hunt for you.

Can we do it as a group?

Yes, and it reads better aloud than alone. Access is held by the browser that paid for it, so buy once and pass the phone round rather than buying one each.

What you get

A walking cipher through the Latin Quarter and across the Île de la Cité. Each riddle points at a place a short walk away. Solve it, prove you're there, move on. Hints are available whenever you're stuck — they just cost you points. Climbing to the Panthéon is the only real effort; after that the river is always downhill.

7 riddles, checked by the server as you solve them
A hint whenever you are stuck. It costs a few points.
A running score, a time, and a certificate at the end

Where does it go?

That is the game. A hunt tells you nothing but the first riddle; the place it points at is what you work out, and printing the list here would be printing the answers. What we will say is the shape of it: 7 riddles, 3.4 km, about 2 h, and every stop is somewhere you can reach and see without paying an admission.
