Instructions
Determine the route you want the players to follow until they reach the treasure. Write it down on a notepad, leaving some rows of space between areas.
Write the clue next to each location or space listed on your notepad. Depending on the player's level, you can either say directly what they have to do -- "Go to the living room and search under the television" -- or mention a riddle, such as "Through it you can see the world, but under it, you can see the clue."
Cut out as many 3---3-inch pieces of paper as your locations. Copy the clues from the notebook to the sheets. Use clear handwriting, so that everyone can understand what you have written.
Place each piece of paper at its corresponding position. Ensure a paper is not easy to spot when players don't know where they should focus. For example, if your clue is supposed to be on the desk, put it under a book, so that an unsuspecting "hunter" entering the room won't be able find it.
Hand every individual or team participating in the game the initial clue. Also give them a map of the area the game takes place -- a house, a garden or even a neighborhood -- to place a mark on the position of each clue they find. This way, you ensure the winner has followed the complete route and did not just find the treasure by chance.
