Question by question
A question scores 100 minus the bracket’s width as a percentage of the track, if the answer is inside it, and nothing if it is outside. The tenth-of-the-track bracket below is the one a confident player was aiming for.
- How many squares are on a Sudoku grid? 81 — near the middle of its track. A bracket from 72 to 90 is a tenth of the track and scores 90; the whole track scores 0.
- How long is the border between the United States and Mexico? 1,954 miles — in the lower third of its track. A bracket from 1,750 to 2,200 is a tenth of the track and scores 90; the whole track scores 0.
- How many compartments does a cow’s stomach have? 4 — near the middle of its track. A bracket from 3.55 to 4.45 is a tenth of the track and scores 90; the whole track scores 0.
- How many feet are in a mile? 5,280 — near the middle of its track. A bracket from 4,850 to 5,750 is a tenth of the track and scores 90; the whole track scores 0.
- How many hours are in 5 weeks? 840 — near the middle of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 670 to 1,100 is a tenth of the track and scores 90; the whole track scores 0.
