Largest Lakes by Surface Area Quiz

How well do you know the largest lakes by surface area? Floored turns the ranking into a building: floor 1 is the top of the list. We name a floor, you guess what's on it, and the lift rides to whatever you picked so you know to go higher or lower.

How it works

You get a few guesses per floor. Land it on your first guess for 10 points; a near miss still scores. After the lakes round, four more lists from the same topic keep the ride going.
