Three daily games, one ruler. Slide the marker and land as close to the truth as you can. Five prompts each, no timer, no tricks.
How long does it last? When did it happen? How old is it?
Drag, tap or nudge it along the ruler. It’s a scale, not a stopwatch: on How Long every tick is ten times longer than the last.
See the truth and how far off you were. Up to 100 points a round, 500 a game.
Real rankings, higher orbits. Type one answer in 20 seconds and see how high it climbs.
