First you have to prepare the clues. Get some little pieces of paper - you can use fancy coloured card or parchment or simply scraps from a jotter notepad, it's really up to you. Then decide which places you're going to hide the clues. It's best if you find places around the house where they won't be seen by accident - if your child accidentally finds one out of turn, it could break the surprise.
For each place, try to think of a clue that will lead to it. For example, if you're going to hide one in a grandfather clock, the clue might say, 'This is a tall tick tock tick tock'. If you're going to hide one in the washing machine (careful nobody does a washload in the meantime!) it might say, 'Socks and suds go round and round'. You can make them easy or difficult, depending on how long you want the game to last.
Once you've got around ten clues, plant them in order so that they create a continuous trail. Then, at the end of the trail - put the present!
Once everything's ready, present your child with the clue and explain that they have to work out what it means - they'll soon get the hand of it and be adventuring away!
