Easy — logic-grid deduction puzzle
Four friends camped on the pavement for show-court seats, but after a sleepless night they could not remember who arrived when or who brought which snack.
On the night before play began, Oliver, Harriet, George and Imogen rolled out their sleeping bags on the pavement. If they could keep their places in the line until morning, they would get seats on a show court. They turned up one at a time, and each of them brought a different snack to share. Nobody slept much. By sunrise, none of them could remember who had come when, or who had brought what. Can you help them sort it out?
