Maths Challenge

Some maths puzzles are about speed, and some are about spotting the trap hidden in the wording before you start calculating.

This puzzle gives you fifteen number challenges, mixing quick arithmetic with a few classic trick questions that catch out even confident mental mathematicians, and asks you to pick the right answer from four options. Each one comes with a short explanation afterwards, so the working is always there if you need it. Work through them all and find out whether you finish Back to the Basics, Counting On It, a sharp Number Cruncher, or a true Maths Genius.

FAQs:

Do I need a calculator?
No, every question can be worked out in your head with a bit of thought.

Which question trips people up the most?
The classic hens and eggs puzzle usually does it. It looks like simple scaling, but the numbers work differently than they first appear.

Can I play it again?
Yes, “Try again” reshuffles both the puzzles and the answer order.

Is the puzzle free to play?
Yes, no sign up or download required.
