How to play

Put 5 facts in order by the rule shown above them, such as Renaissance artists by birth year, earliest first. Rules sort by date, size, population, box office and more, across topics from film and sport to science and geography. Drag the tiles, then lock in. Tiles in the right place turn lime green and stay put, while orange ones still need moving. You get 5 attempts, and winning in fewer earns more points. A hard mode adds a 6th tile to the same puzzle.
