13 Thanksgiving riddles the whole table can actually solve

Heron

I'm Heron. I do arithmetic in my head for a living, and my cousin got me with that bread basket two Novembers ago, in front of nine people and a cooling turkey.

So these thirteen are the ones a table can work out. Nobody needs a date, a name, or a fact they were supposed to have memorized.

Why the basket runs backwards

The empty basket is the one number the riddle gives you for free. Start there and undo a single guest at a time.

Undoing a guest takes two moves: add one, then double. Add back the extra roll they took, then double it for the half that left with them.

That is The Oven Clock from our Thanksgiving trivia, working on bread instead of a bird. Let's run it on a cookie tin with a greedier rule: half the tin plus two, three kids, empty.

Thanksgiving riddles for adults, where the numbers lie

Six riddles with numbers in them, and the numbers are the liars. None of them needs a fact you already own, so nobody at the table loses for not knowing something.

The bread basket up top was riddle 1, so we pick up at 2. Commit to an answer before you open the card, and keep a private tally: the scoreboard at the end wants a number from you.

Thanksgiving lands on November 26 this year, so the Thanksgiving math riddles below are the half worth rehearsing first. Riddle 7 is the one to save for the table: the fourth Thursday of November can never arrive later than the 28th.

Riddle 2 of 13

Ten guests each eat one drumstick and nobody shares. What is the fewest turkeys that were carved?

Riddle 3 of 13

Each square card table seats four, one to a side. You push three of them into a row. How many seats?

Riddle 4 of 13

The kitchen scale stops at 11 pounds. You weigh 152 alone and 165 holding the turkey. How heavy is it?

Riddle 5 of 13

Half the table takes pumpkin pie, a third takes pecan, and the last three take neither. How many sat down?

Riddle 6 of 13

Your aunt is two hours behind you. She calls at 3:00 her time. Dinner is at 4:00 yours. Is she late?

Riddle 7 of 13

Thanksgiving is the fourth Thursday of November. What is the latest date it can land on?

Riddle 3 is the one that quietly ruins a seating plan. Two tables touching hide a side each, and the chairs disappear with the sides, the same way a Secret Santa turns 56 gifts into 8.

Heron

Round two puts the arithmetic away. The trap moves into the sentence, and sentences travel down a dinner table far better than numbers do.

Fair warning: the youngest guests usually win this half. They answer the question as written, which is the entire skill.

Thanksgiving riddles for kids, and one that catches every adult

Six riddles, no calculator, nothing to look up. The answer to each one is sitting in the sentence, so the youngest guest gets there as often as anybody.

One habit clears most of them: take every word literally, scenery included. Riddle 8 is the exception and the meanest thing on this page, so hand that one to the adults.

Read them aloud if you can. A sentence gives itself away faster in the open, and the table hears the trick a beat before the person holding the phone does.

Riddle 8 of 13

You drive 60 mph toward Grandma's, she drives 40 mph toward your house. When you pass, who is closer to her?

Riddle 9 of 13

When does Christmas come before Thanksgiving?

Riddle 10 of 13

What three keys open no doors, and one of them is sitting on your table tonight?

Riddle 11 of 13

The more of me you take out of the pie tin, the bigger I get. What am I?

Riddle 12 of 13

It has to be broken before anyone can cook with it. What is it?

Riddle 13 of 13

Take the thanks out of Thanksgiving. What word is left, and what does it ask you to do?

Every trap on this page runs on one reflex: the answer that arrives before you finish reading. Psychologist Shane Frederick built a famous three-question test out of it, and at Harvard, MIT, and Princeton most students grabbed the fast, wrong answer.

We named that reflex The Candy Trap in our Halloween riddles, and it works the same on a highway as it does in a candy aisle. The missing dollar riddle runs on the same nerve if your table wants a third round, and a stable with fourteen heads and forty legs waits a month later.

What to remember

Heron
  • Start where the story ends. When a riddle tells you how it finishes, undo it one step at a time: baskets, ovens, and connecting flights all give way to that.
  • Count the thing the question asks for. Drumsticks, birds, and guests are three different numbers, and only one of them is ever the answer.
  • Get both numbers onto the same clock. Time zones, halves, table sides: compare things only once they are measured the same way.

Honest tally: how many did you solve without peeking?
