You may request validation of your proposed location before traveling, simply by emailing the puzzle creator. If your answer is correct, they will call you within one week (excluding holidays or exceptional circumstances). If you do not receive a response after two weeks, your solution is not correct.
This system was initially designed for international players or those with physical disabilities, but it is free and open to everyone. It will remain available as long as the volume of validation requests remains manageable for the puzzle creator. If you are able to travel to the chest’s location, please limit validation requests to a maximum of once per month.
For The Golden Elixir and Exkalibur, even if your location is correctly validated remotely, the chest must still be physically unearthed (by yourself, a team member, or a trusted person). Only possession of the item contained in the chest will officially declare you the winner.
