Puzzles where one careful read, or a sideways idea, unlocks a single correct answer.
A notebook and a pen cost $1.10 together. The notebook costs exactly $1.00 more than the pen. How much does the pen cost?

5 cents

No riddles match both filters. Try another age or difficulty.
Read the riddle twice and underline words that can mean two things, such as 'stories', 'hands' or 'break'.
Give hint 1 after about a minute of thinking, and hint 2 only if the group is still stuck.
For logic puzzles, let kids draw it: a line of names, a table or a few quick sums on paper.
Ask for the reason before you reveal the answer. A child who can explain the trick has really solved it.
Take turns being the riddle master: the person reading must also know the one-line explanation.
The first 15 suit ages 7 to 9 and the other 25 suit ages 10 to 12. Each riddle is tagged with an age band and a level, so you can pick only the ones that match your child or class.
Give hint 1, then wait. If that does not help, give hint 2, which nearly gives the answer away. Praise the effort, then read the one-line explanation together so the trick is ready to use on the next riddle.
A clue can fit more than one object, but an answer must fit every clue in the riddle. Ask your child to explain their choice. If it fits the whole riddle, count it, then read the explanation together.
Yes. Each riddle prints as a card, and the answer key prints separately so children cannot see the answers. Cut the cards up for a station activity, a lunchbox or a car trip.
Read one riddle aloud and let teams whisper a guess. Teams score 3 points for an answer with no hints, 2 with one hint and 1 with two hints. The hints make the scoring fair.
