It contains details of the start and finish points, as well as the contact details for the end venue should you wish to reserve an area or arrange food.
There is then a leaflet of guidelines that explains how the treasure hunt is structured and gives useful pointers on the best way to operate your treasure hunt.
There are also two sealed envelopes, both marked "Top Secret". The first contains a detailed guide to the treasure hunt route and tells you where the clues are. The second envelope contains all the answers to the Observation Questions and the Photo Challenges for marking the sheets at the end of the treasure hunt.
Finally, we provide you with a score card on which the team scores can be written and which can then be used when it comes to announcing the winning team and the number of points each team scored.
The Guidelines leaflet provides the organiser with a full breakdown of how the treasure hunt works along with advice on the best way to conduct the event.
In addition, it gives tips on when to hand out the packs to the teams, and gives valuable advice on the best and fairest way to mark the challenges when the teams reach the end of their treasure hunt.
You will also find our phone number on here should you have any questions or wish us to advice on anything that you are unsure about.
The sealed route envelope is provided as an emergency back up. To be honest, as long as the teams read the clues and do exactly what they are being told to do they should have no problems.
However, in the event of an emergency - a sudden road closure for example - you can open the route envelope and inside you will find full details of the route along with the solutions to each of the cryptic clues.
Again, the Answers envelope is sealed and should not be opened until all the teams have completed their treasure hunt and handed in their packs.
On opening it you will find the answers to all the Observation Questions and all the Photo Challenges.
The best way to mark the treasure hunt is for the teams to switch packs with the team nearest to them and then read out - or get someone else to read out - the answers to all the challenges.
As you mark the answers simply enter the total for each section into the round circle on the score card and then add up the Observation Questions score and the Photo Challenges score to give the Grand Total.
You can then place the score cards in order from the highest to the lowest scores and then read out the scores that each team has achieved.
We suggest reading out the lowest score first, and then build up the tension as you approach the highest score and the winning team.
The team folders contain everything the teams will need to complete their treasure hunt.
Each pack contains a pen for writing the answers to the Observation Questions and Photo Challenges.
On opening the pack the teams will find the exact directions to the starting point for the treasure hunt. This will be outside an Underground Station, and we will give full details of which exit they will need to go to to get started.
Most of the starting points have pubs or coffee shops by them, so, if they wish, the teams can go into one of these to read their briefing notes and plan their strategy.
Once the teams have read and understood their Briefing Notes, they simply read the "STARTER" on their Cryptic Clues sheet and follow exactly what it says to do.
The briefing notes leaflet provides the team with full instructions on how the treasure hunt works and what challenges they must accomplish.
Each of the three challenges has its own detailed section explaining exactly what the teams must do in order to complete each task.
It also features an advisory safety section, warning about potential hazards, such as crossing roads and avoiding obstacles.
The teams will need to read these briefing notes before they set out on their treasure hunt.
The Cryptic Clues, which are printed on waterproof paper, are what the teams use to move around the route. All the clues are visual and directional, so the teams don't need any knowledge of the area, nor of the history of the area. They just need to read - as opposed to simply scan - the clues and follow what each clue is telling them to do.
Teams begin by following the "STARTER" clue. Using directional and visual prompts this will lead them to a location where they will find the solution to the clue. It might be on a blue plaque, it might be on an information board, or it might be on the plinth of a statue. When they find it they will need to perform the task set for them in the clue, and this will give them a letter or a number which will correspond to the next clue that they must follow.
They then follow that clue, at the end of which they will perform another task to get the letter or the number of the next clue, and so on and so forth until they reach the end point.
There are, however, several "Red Herring" clues that they will not need to solve. These are simply there to stop teams working a process of elimination to figure out when they are nearing the end of their treasure hunt.
As they make their way around the route, each team must answer 20 observation questions. The answers will be found on items they will pass en route.
They might be on blue plaques, on information boards, on items of street furniture, on statues, on the pavement stones they are walking on; and, in some cases, they might even be on gravestones in churchyards!
The teams will need to keep keen eyes peeled to ensure that they don't miss any of the answers.
The Photo Challenge often proves the most difficult of all the tasks that the teams must undertake as they make their way around the treasure hunt route.
There are ten photos of items that the teams will pass on the route and which they must identify in order to complete the challenge.
However, some of the items are a lot smaller in reality than they appear to be on the photos. Some of the images have been Photo Shopped to change bits of information or to alter something on the item (thus creating a spot the difference challenge), whilst others have been photographed from odd angles to make identifying them slightly more challenging.
All that can be truly said about them is that they will be there, somewhere on the route. So it is a real test of the participants observational skills to see if they actually will spot them.
This challenge can often make the difference between a team finishing in first place or second place, as some teams are more observant than others!
"I just wanted to say thank you very much on behalf of my team for preparing the brilliant Greenwich Treasure Hunt, which we all took part in last Friday.
Everyone thoroughly enjoyed themselves – with competitive streaks coming out of some unsuspecting members!
People have been asking me for your details as they were so impressed, so I won't hesitate in recommending you.
We have also all definitely become more observant in the past few days, looking up and around at things we wouldn't normally spot!
