This Wherigo converts your player into a 'Reverse-Cache-Box'. This box will tell you the distance to the final cache, but not the direction.
All you will need is a Smartphone or GPS device which is capable of playing Wherigo.
The cartridge created by -Waldmeister- is available for download here (The Reverse Cache - Beta).
To play this Wherigo cartridge, your mission is to find the cache with only the information about your distance to the final location. Try to use your Reverse Cache box as few times as possible. It is possible to figure out the final coordinates in three attempts. How low can you go? All the instructions and information needed to complete this cartridge is contained within it. The cartridge is multilingual and may be used with either metric or imperial units.
You will need to type this code into your player when prompted:
502365
634160
823600
Take the code with you on your quest, you might need it if there is a problem with your player.
Optional: You will be given some statistics when you reach the final. It would be fun if you post the details in your log and also post the number of times that you have calculated the distance.
You will also receive a personal password which may be entered into the code generator if you select 'create' instead of 'play' at the start of the cartridge. Save this code. Then if you wish, you may place your own reverse cache in a location of your choice. (Just tell -Waldmeister- about your plans!).
Please don't write any hints in your log about how and where you found the cache and please don't post any photos that might give the final location away.
Have fun and be careful out there!
