Questions
Where do the riddles come from?
We wrote them ourselves for this site, with their hints and explanations. You will not find this exact set anywhere else, and new ones are added from time to time.
How are number answers checked?
The numbers in your answer are compared with the numbers in ours, in any order. Units and currency signs (kg, km/h, ₹, years) are optional.
Are they good for school students?
Yes. Most need only arithmetic, fractions and simple reasoning, the level of classes 5 to 9. A few, like the clock and train puzzles, stretch older students.
