These worksheets provide the opportunity for students to practice basic transformations. A favourite with staff at my current school, I regularly see piles of them coming off the photocopier.

Disarm The Bomb
Like the 'Locked Box Problem', Disarm The Bomb has students work towards an overall lock code. An old mobile phone has a countdown set and is locked. Students have to disarm the bomb before it goes off. To theme the activity, get seven kitchen roll tubes, wrap them in red paper, arrange them in a hexagon, wrap black tape around and use black pipe cleaners as a fuse.

Originally seen as a 'writing prompt', the images have given me a starting point to adapt 'The Secret Code' to a classroom-ready problem solving activity.
Press pause when it's silent and give kids time to work, a bit of scaffolding offered by offering one option for solving and the answer at the end.
