How does it work?

Welcome

Welcome to Sil's GeoCaching

This app uses your camera and GPS. Point your camera at your surroundings and Sil will appear.

I'm Sil and I'll show you the way today. Do you see me together with the deer? Then you're not at the coordinate you're looking for yet.

Camera and GPS use a lot of battery: set off with a full battery.

Rules

How does it work?

1. 1

   When you're standing on the right coordinate, Sil appears with a letter. Write that letter down!

2. 2

   Tap Sil: you'll get a riddle or a task. Solve it to find the next coordinate.

3. 3

   Every two minutes a new tip unlocks. After 10 minutes you'll see tip 4: the full coordinate.

4. 4

   Stuck? Take a moment to rest.

The next coordinate is never more than 1 kilometre away and never in a built-up area.

Coordinates

The different GeoCaching systems

Sil works with 3 kinds of GPS coordinates. All three lead to the same spot:

• 52.09794 5.82887WGS · decimal degrees
• N52 05 52.6 E5 49 43.9WGS · degrees, minutes, seconds
• 185264 456725RD · Dutch national grid

Type a coordinate into this app's navigator. It understands all three systems and shows you the way.

Letters

Collect the letters

At every location Sil gives you a letter. Write them down, because at the end the letters form a word together.

You can also note the letters in the app with each clue.
