The five questions everyone played that day, in the order they were asked, with the correct answers and why they are right.

Too few players took part this day for results to be shown.

1. Question 01 · Puzzle · Easier · Pick one

   If yesterday was Friday, what day is tomorrow?

   • Saturday
   • Sunday✓ Correct answer
   • Monday
   • Thursday

   If yesterday was Friday, today is Saturday and tomorrow is Sunday. Pin down “today” first, then move from there.

2. Question 02 · Knowledge · Easier · Put in order

   Put these in the order they happened, earliest first.

   Correct order

   1. Gutenberg's printing press
   2. The first telephone call
   3. The first Moon landing
   4. The first iPhone

   Gutenberg's press dates from about 1440, the telephone from 1876, the Moon landing from 1969 and the iPhone from 2007.

3. Question 03 · Puzzle · Medium · Pick one

   Ten coins, all 5-cent or 10-cent coins, add up to 75 cents. How many are 10-cent coins?

   • 3
   • 4
   • 5✓ Correct answer
   • 6

   If all ten were 5-cent coins you'd have 50 cents; each swap to a 10-cent coin adds 5 cents, and you need 25 more, so 5 swaps. Check: 5 × 10 + 5 × 5 = 75.

4. Question 04 · Estimation · Medium · Pick a point on a scale

   Walking nonstop at 5 km/h, roughly how long would it take to walk around the equator (about 40,000 km)?

   • About 1 month
   • About 11 months✓ Correct answer
   • About 3 years
   • About 10 years

   40,000 km ÷ 5 km/h = 8,000 hours, and 8,000 ÷ 24 ≈ 333 days — just under a year of walking without a break.

5. Question 05 · Estimation · Harder · Pick a point on a scale

   Roughly how old is Earth?

   • About 45 million years
   • About 450 million years
   • About 4.5 billion years✓ Correct answer
   • About 45 billion years

   Radioactive dating of meteorites and the oldest rocks puts Earth at about 4.54 billion years — about a third of the universe's age.
