Sixteen subjects appear mixed up: people, places, works or events, all drawn from Wikipedia. They form four groups of four, each linked by a hidden common thread, such as the same art movement, the same era or the same country. Select four subjects and submit: if all four belong together, the group is revealed with its name. If three out of four are right, Curio tells you. You are allowed four mistakes. Groups range from the most obvious to the hardest, and some subjects seem to fit several groups: that is the trap. At the end, the full solution is shown and you can share your result without giving the answer away. The puzzle changes every day at midnight (UTC) and is the same for everyone. Two ways to play Categories: the daily challenge, the same puzzle for everyone, renewed every day at midnight (UTC), one game per day, with a day streak and coins to win; and free play, unlimited, where a new puzzle is drawn for every game, with no reward, so you can practise as much as you like. In free play, the solution is always shown at the end.
