Ten questions make 1,024 sheets.
Each question doubles the pile: 2, 4, 8, 16, and ten doublings land on 1,024. One sheet in there is perfect, so guessing your way to a clean sheet is a one in 1,024 shot.
So we play it in rounds.
A numbers round you can work out at the table, a words round with a theme hiding in it, and the tiebreaker that decides the night.
I'm Heron. I have hosted exactly one quiz night, and I lost control of it in round two, when I read the answers out in the wrong order and awarded a point to a team that had written nothing.
That answer sheet was question 1. Nine more below in three rounds, and nobody is marking them, so let's keep each other honest.
Why nobody guesses a round and wins it
Ten true-or-false questions feel guessable. Coin-flip them all and you land on five, which is a respectable way to lose every round of your life.
The clean sweep is what we are after, and guessing cannot reach it. Every question doubles the pile of possible sheets, so the perfect one is a single sheet out of 1,024.
Let's shrink the round to seven questions and count the pile again.
2β·Β =
Same rules as above. You've got this.
Round one: the numbers round
Four questions, and every answer is something you can work out at the table. No dates, no capital cities, nothing you were supposed to have read.
We pick up at question 2. Keep an honest tally: the scoreboard at the end asks for it, and so does the person you send this to.

Riddle 2 of 10
The quiz is called for 3:30 sharp. What angle sits between the two hands of the clock at 3:30?
Hint: The hour hand does not wait at 3 while the minute hand travels.
75Β°
β180Β° β 90Β° = 90Β°the gap if the hour hand waited
1hour hand = 3.5 Γ 30Β° = 105Β°it covers 30Β° an hour
2180Β° β 105Β° = 75Β°the minute hand sits at 180Β°
Half past moves the hour hand half a step as well, and that half step is the whole question.
Riddle 3 of 10
Four of you take seats 1 to 4 at the quiz table. How many different seating orders are there?
Hint: Fill the chairs one at a time and count what is left for the next one.
24
β4 + 3 + 2 + 1 = 10adding the choices instead of chaining them
14 Γ 3 Γ 2 Γ 1 = 24each seat narrows the next
Choices in a row multiply, which is the move the answer sheet made ten times over.
Riddle 4 of 10
How many pips are there on a pair of standard six-sided dice?
Hint: One die first, and its faces run 1 through 6.
42
β6 Γ 6 = 36six faces of six pips, which no die has
11+2+3+4+5+6 = 21one die, every face counted
221 Γ 2 = 42the pair doubles it
A die carries one of each number, so the six faces get added up.
Riddle 5 of 10
The quizmaster says the answer is a three-digit number, all digits the same, adding to 12. What is it?
Hint: One digit, three times over.
444
13d = 12three matching digits, total 12
2d = 4, so 444check it: 4 + 4 + 4 = 12
Hunting for three different digits that add to 12 gives dozens of answers and skips the word βsame.β
Question 3 is the one that pays off away from the quiz. Four chairs make 24 orders because each seat narrows the next, which is the same chain the answer sheet ran ten times over.
Round two is where I lost my own quiz night. One theme runs through all four answers, and not one question prints a digit.
We're calling a theme like that a gift. Catch it on question 6 and you can hunt the other three down instead of sitting there waiting to remember them.
Round two: the words round
Four questions, one theme, and not a digit in sight. Let's catch the theme on question 6 and spend it on the three that follow.
Spelled out in English, which number has exactly as many letters as its own value?
Hint: Spell the small ones out and count the letters as you go.
Four
βthree β 5 letters, value 3the name still runs ahead
1four β 4 letters, value 4the only number where they match
Number names grow slower than numbers do, so four is the one place the two cross.
Riddle 7 of 10
Spelled out in English, which number has all of its letters in alphabetical order?
Hint: Try the tens before you work through the small ones.
Forty
βone β o, n, en lands after o, so it fails
1forty β f, o, r, t, yevery letter later than the last
Checking the first ten numbers and giving up is how this one gets away.
Riddle 8 of 10
Count upward in US English: one, two, three, and on. Which is the first number to use the letter A?
Hint: Spell each one out as you climb and watch for the first A to show up.
One thousand
βhundred β h, u, n, d, r, e, dno A in any name below it
1one thousandthe A finally arrives in thousand
All 999 names under it dodge the A, and a British table counting βone hundred and oneβ gets there at 101.
Riddle 9 of 10
O, T, T, F, F, S, S. The quizmaster wants the next letter in that row. What is it?
Hint: Say the row out loud as the start of something you count.
E
1O, T, T, F, F, S, S = one to sevenfirst letters of the numbers
2eight β Ethe eighth number gives the eighth letter
Read as a letter puzzle the row stays meaningless, and read as counting it ends on the spot.
The theme was spelling. Four, forty, one thousand, and E for eight: the whole round turns on how numbers look in letters.
Round three: the tiebreaker, closest guess wins
A quiz night that ends level gets settled by a number nobody in the room knows. Bricks in the building, steps to the top of the tower, and the jar of beans we are taking here.
Most tables shout. We're calling that The Shouted Number: a figure with nothing underneath it, and it loses to two lines of arithmetic every time.
Riddle 10 of 10
The night ends level. The jar is 6 inches across and 8 inches tall, packed with jellybeans. How many?
Hint: Work the jar out in cubic inches, then take away the air between the beans.
2226 Γ 0.6 β 136 inΒ³call a packed jar 60% bean
3136 Γ· 0.05 β 2,700a bean runs about a twentieth of a cubic inch
Say both assumptions out loud and the table can argue them into another number, which is the whole point.
Our estimate wins without being right. Closest takes the prize, so a worked number in the right thousand beats a confident number in the wrong one.
One famous crowd managed it without any arithmetic at all. Galton reported that the middlemost of 787 guesses at an ox's dressed weight came in 9 pounds high, 0.8 percent off, and a later reading of his own papers puts the real miss a little wider.
A table of four falls a long way short of 787 people, so we do the arithmetic instead: a volume, a fraction for the air, and the size of one bean. That is the slow, checkable kind of mental arithmetic, and it is the only part of a quiz night you can practice.
What to remember
Every question is a fork. Ten two-way questions make 1,024 sheets, so guessing lands you on five of them and never on all ten.
Hunt the theme. A themed round hands you half of every answer before you remember a thing, so find it early and spend it.
Say your assumptions out loud. A jar estimate with its numbers showing beats The Shouted Number, and the table can argue with it.

FAQ
Trivia is a question-and-answer game, usually played in teams over several rounds, with a point for each right answer and a spare question held back in case two teams finish level. This page is one night of it in three rounds: numbers, words, and the tiebreaker.
One person reads the questions out, everybody writes answers on a sheet, and the sheets get marked at the end of each round. Hold every answer until the whole table has committed, keep a running total, and settle a draw with a closest-guess question rather than a coin.
You can guess your way to about half of a true-or-false round, since ten coin flips land on five. What guessing cannot reach is a clean sheet: every question doubles the pile of possible sheets, so the perfect one is a single sheet out of 1,024. Quiz nights are won on the questions one table works out and the other table flips for.
A number nobody in the room knows, where the closest guess wins: beans in the jar, bricks in the building, steps to the top. It can never end in a draw the way a knowledge question can, and it rewards the team that estimates out loud instead of the team that shouts.
Ten is the size most tables can play without losing the thread, which is why a standard answer sheet has ten lines. The shape of the night matters more than the length: a short round of numbers, a round with a theme running through it, and a closest-guess question held back for a tie. That is the night on this page, cut down to ten questions in total so you can play it in one sitting.
