1 clue and 5 seconds to find the right word!
First, you will need to find a word starting with the letter drawn and corresponding to the imposed theme. Once you have a proposal, you will have to make your partner guess it by giving him a hint! The latter will have 5 seconds to find the answer.
For example: the theme of the trick is "it flows", the imposed letter "T", and your clue the word "fast". GIVE ME 5...4...3...2...1... You and your partner together give the "torrent" answer.
It's a done deal!
