Poirot meets his Waterloo (WIG) Wherigo Cache

As an attempt to reintroduce the Whereigo cache to Singapore, I have designed this Whereigo as a simple field puzzle Multi along Waterloo Street. The story is built around Agatha Christie's Hercule Poirot, who has come to Singapore with his friend, Captain Hastings, to investigate the loss of a piece of artwork from the Singapore Art Museum.

Wherigo caches are interactive GPS-device based games which can be quite a lot of fun if you willing to learn the ropes. This type of cache has been noticably absent in Singapore in the past couple of years, so I've decided to try my hand at it. As long as you have a GPS-enabled device, like a smartphone (Apple and Android), a few models of Garmin GPSr or Pocket PC, you will be able to run the catridge. The following is a step-by-step guide on what to do:

1. If you have an Apple device, such as an iPad or an iPhone, you can download this free Wherigo app. Android phone users will have to download this (also) free app, called Whereyougo, for their devices. Garmin GPSr should already have the application pre-installed
2. Ensure that the Location Services in your device is enabled. This can usually be found in the "Settings > Privacy > Location Services" for Apple devices. Be sure to set it to "On". 
3. Once the application has been installed, be sure to give it authorisation to log onto your Geocaching Account. This is found somewhere in the app (under "Search" for Wherigo and "Settings > Global" in Whereyougo)
4. Download the game catridge from the Wherigo website. It's all completely free, too. You can download it directly into your device, or through an external computer and transfer it later. Once the catridge is downloaded into your device, just pick "Run with Wherigo/Whereyougo" if prompted, and the catridge name should appear in the application immediately.
5. If the download is successful, you should see this:
6. Tap the catridge name, and a brief description of the catridge will appear, as such:
7. Tap "Play" and this screen should appear, with Locations (1) [The Singapore Art Museum]. If there is no number beside the "Locations", you need to reinstall the catridge.
8. Tap "Locations", and you will receive the starting coordinates. Once you get there, the game will begin! Exciting, isn't it? I won't spoil what happens next.

Just a couple of other IMPORTANT technical notes before you start on this adventure:

• The events (which include dialogues and puzzles) for each location will appear in your device about 50 metres away from the actual coordinates. Once these appear, the game assumes you have reached the target area and you will no longer see the coordinates for the WP. Therefore, if you need to know EXACTLY where to go or want to narrow the search area, YOU MUST take down the coordinates when you see the "Welcome to..." screen, which will look like the screen in Step 8. You can input the coordinates as next stage in the Geocaching App if you still need to navigate to the spot. Or, if you like an extra challenge, then just go ahead. You will have a larger search area to solve the puzzles.
• There are hints in the text, so don't skip them thinking they are irrelevant. Unfortunately, you will not be able to go back and read the text again... so, pay attention to the details, or the puzzles will be harder than they should be.
• You will NOT need to enter the premises of any of the buildings in the game (though in one case, you'll need some pretty sharp eyes). All the clues can be found from the street.

Have fun trying out this WIG, and do keep an open mind and be patient. The software is not perfect and this is my first time trying out a WIG, and there will always be a kink or two to iron out. I have both an Apple and Android device, so I can help out if you have issues there, but unfortunately I am clueless on how it works on the Garmin GPSr. In any case, let me know if you run into any trouble at any stage, but keep in mind the notes and warnings stated above.
