Puzzle: I have a 5 × 5 grid, in which the squares can either be empty (white) or infected (black). The four ‘neighbours’ of each square are the ones directly next to it: up, down, left and right. A square will become infected if two or more of its neighbours are infected. Can you find a set of squares to colour black (‘infect’) which will eventually spread the infection to the whole grid? What’s the smallest number of squares you need to do this?
