Daubed on the wall of the gym in 3 foot high letters at some unknown point in the school's history. Whilst being erased (quite soon after appearing, one assumes) the letters were still clearly defined, even from 300m away at the other end of the school field.

Strangely, any camp commandant had left by the time I joined, but house head 'Uncle' Beresford seemed quite willing to fill the role. Canteen food was perhaps the most obvious remnant of this hushed period of the school's history...

Colditz was also a game played indoors, preferably in a room full of furniture. Rules as follows:

Take one room. Pile tables, chairs, anything in the middle of it to form a baricade. One person is the guard, the others are prisoners trying to escape. Tha aim was to climb through the wreckage with all the lights off making as little noise as possible, if you made a noise the guard would shine a torch at you, and if you were caught moving you were out. And also trapped under about three tables.

Unsurprisingly this game wasn't so popular with whoever had to tidy it up afterwards.

Also the name of a game played by my cub scouts group, before we all realised that cub scouts were slightly gay.

The game involved grabbing all the furniture we could find (the place was packed with wooden chairs and fold-out tables) and piling it all up to create a barrier across the middle of the room. All the lights would be switched off, and the elderly scout leader would then stand at one end and shine torches at us whenever he heard a sound. If we were caught moving, we were out of the game. Of course, this lead to more noise and pushing furniture about onto each other. Several hundred splinters and a few serious injuries later, they put a stop to the game. Possibly because one night we piled furniture up at corners of the room into forts, and threw plastic skittles at each other until someone got hit in the eye.
