Thanksgiving Brain Teasers With Answers for Teens
Here are 20 Thanksgiving brain teasers with answers, sorted from easy riddles to hard logic puzzles that will actually stump the adults. Every answer is at the bottom, so you can read one out loud, let the table argue, then reveal. Most lists online are written for 7-year-olds. This one isn't.
If you get bodied by the math ones but cruise through the riddles, that's a real pattern, and IQ Tester shows you exactly which kind of reasoning is your weak spot: Find my weak spots.
Thanksgiving riddles to warm up
Start easy. These are the "everyone gets a win" round while the turkey is still in the oven.
- What key won't open any door, but shows up at every Thanksgiving?
- I have ears but I can't hear, and I'm usually buttered. What am I?
- The more of me you take, the more you leave behind. (Hint: think about the walk to Grandma's front door.)
- What has a neck but no head, and gets passed around the table all night?
- I'm stuffed every year, but I never complain about being full. What am I?
These also work as icebreakers at a Friendsgiving.
Thanksgiving math brain teasers
This is where the "I'm not a math person" uncle quietly leaves the room. Each one has a trap built in.
- The oven trap. A turkey takes 3 hours to roast. How long does it take to roast 3 turkeys side by side in the same (very big) oven?
- Pie cuts. You cut a round pumpkin pie with 3 straight cuts. What is the most pieces you can get?
- The whipped cream one. A pie and a can of whipped cream cost $11 together. The pie costs $10 more than the cream. How much is the cream?
- Handshakes. 12 relatives arrive and everyone shakes hands with everyone else exactly once. How many handshakes?
- Cousin speed. If 5 cousins eat 5 slices of pie in 5 minutes, how long do 100 cousins take to eat 100 slices?
- Number series. Guests keep arriving in this pattern: 1, 1, 2, 3, 5, 8... How many arrive in the next group?
Why the math ones feel so hard
Number 8 is a version of the famous bat-and-ball question from the Cognitive Reflection Test. Your brain shouts "$1!" before you've done any math. The skill being tested isn't arithmetic. It's catching your own first answer and checking it. That's also why school maths (UK) or math class (US) grades don't always predict who wins this round.
Logic teasers for the table
These need a bit of back-and-forth. Perfect for when everyone is too full to move.
Who ate the last slice? Three siblings are accused. Avery says, "Blake did it." Blake says, "I didn't do it." Cam says, "I didn't do it." Only one of them is telling the truth. Who ate the slice?
The seating chart. Uncle Joe, Grandma, cousin Leo and Aunt May sit in a row of four chairs, numbered 1 to 4 from left to right.
- Grandma isn't at either end.
- Leo sits directly to Grandma's right.
- Uncle Joe sits at an end.
- Aunt May isn't next to Grandma.
Who sits where?
- The mislabeled jars. Three jars sit on the counter labeled "Cranberry," "Gravy" and "Mixed." Every label is wrong. You can taste one spoonful from one jar. Which jar do you taste so you can fix all three labels?
A quick tip for logic puzzles
Write it down. Seriously. Grab a napkin and draw four boxes for the seating chart.
Hard brain teasers for adults
These are the Thanksgiving brain teasers for adults, or for the teen who wants to humble the adults.
The river crossing. A farmer needs to get a turkey, a fox and a bag of corn across a river. The boat fits him plus one item. Left alone, the fox eats the turkey and the turkey eats the corn. How does he get everything across?
The heavy roll. You have 9 dinner rolls. One is slightly heavier than the rest. Using a balance scale only twice, how do you find it?
The age one. Your uncle is 4 times as old as his nephew. In 20 years, he'll be only twice as old. How old are they now?
The 45-minute timer. The oven timer is broken. You have two candles. Each burns out in exactly 1 hour, but unevenly (half the candle doesn't mean half an hour). How do you time exactly 45 minutes for the stuffing?
Pass the rolls. If it takes 2 seconds to pass a basket to the person next to you, how long does it take to pass it from seat 1 to seat 10 at a long straight table?
The leftover question. You have a box of 24 leftover cookies. You eat a third, give half of what's left to your neighbor, then eat 4 more. How many are left?
Answers
No peeking until the table has argued for at least a minute.
| # | Answer | Why it works |
|---|---|---|
| 1 | A tur-key | It's a pun. Groan accordingly. |
| 2 | Corn | Ears of corn. |
| 3 | Footsteps | Each step leaves a footprint behind. |
| 4 | A bottle (gravy or soda) | Bottles have necks and get passed around. |
| 5 | The turkey | Stuffed, never full. |
| 6 | 3 hours | They roast at the same time. |
| 7 | 7 pieces | Each new cut crosses every earlier cut once. |
| 8 | $0.50 | Cream $0.50, pie $10.50, total $11. |
| 9 | 66 | 12 × 11 ÷ 2. |
| 10 | 5 minutes | Each cousin eats one slice in 5 minutes. |
| 11 | 13 | Each number is the sum of the two before it. |
| 12 | Cam | Only "Cam did it" leaves exactly one true statement (Blake's). |
| 13 | Joe, Grandma, Leo, May | See below. |
| 14 | The "Mixed" jar | It's labeled wrong, so it's pure. Whatever you taste tells you that jar, and the other two follow. |
| 15 | See below | Classic ferry puzzle. |
| 16 | Split 3-3-3 | See below. |
| 17 | Uncle 40, nephew 10 | 4x + 20 = 2(x + 20), so x = 10. |
| 18 | Light one candle at both ends | See below. |
| 19 | 18 seconds | 9 passes, not 10. |
| 20 | 4 cookies | 24 − 8 = 16, half is 8, minus 4 = 4. |
13, the seating chart. Grandma is in chair 2 or 3, with Leo right after her. If Grandma is in 3, Leo is in 4, Joe must take chair 1 and May lands in 2, right next to Grandma. That breaks the last clue. So Grandma is in 2, Leo in 3, Joe takes the free end (1), and May sits in 4.
15, the river crossing. Take the turkey over. Come back. Take the fox over and bring the turkey back. Take the corn over (fox and corn are fine together). Come back alone. Take the turkey over.
16, the heavy roll. Put 3 rolls on each side. If one side drops, the heavy roll is in that group of 3. If they balance, it's in the 3 you left off. Now weigh 1 against 1 from that group. Heavier side wins, or if they balance, it's the third.
18, the 45-minute timer. Light candle A at both ends and candle B at one end. A burns out at 30 minutes. At that moment, light B's other end. It has 30 minutes left, burning from both ends, so it finishes in 15. Total: 45.

FAQ
What are some good Thanksgiving brain teasers for adults?
The best Thanksgiving brain teasers for adults have a trap in them, like the pie-and-whipped-cream question (the cream is $0.50, not $1) or the two-candle timer puzzle. Logic puzzles such as the river crossing and the 9-roll balance puzzle also work well because people argue about the steps.
