Insomnia is breaking my brain 
I can remember doing a puzzle as a child in the vein of crossword or word search (or even sudoku) but can't for the life of me recall the name of it or how to actually do it too well. Does it even still exist 
The basic premise, terribly explained:
There was a sort of tetrus shaped grid with squares in.
You were given some info -
Edna likes pampas grass and bourbon biscuits
Roger sings Gilbert and Sullivan while eating cheese cobs
Macolm walks to Monmouth on a Thursday
From the above information and a few intelligent X placements in a grid you'd then be able to work out whether or not Edna was married to a chorister or a barrister.
Can anyone auld like me recall this pastime?
