You are trapped in a prison cell, and the evil guards have set a challenge. They have written one letter of the alphabet on each of nine pieces of card, and placed the cards in the following order on the floor of your cell:
S P A R K L I N G
You have to take away one of the pieces of card, ensuring that the remaining pieces spell a word (and you are not allowed to change the order of the remaining pieces of cardboard), and post it under the door of the cell. And then you have to repeat the process again and again until there is just one letter left. In what order should you remove the letters?
As ever, please do NOT post your answers, but feel free to say if you have solved it and how long it took. Solution on Monday.
