Puzzles

One activity that many of our members enjoy is puzzling! You can test yourself for fun with our brainteasers. Our quizzes and conundrums are updated regularly, so do check back on the page for the latest content, and if you get really good at them, why not find out what your IQ is by booking a Mensa Supervised IQ Test?

11/4/25 – Puzzleland Challenge

In Puzzleland, competitors take part in a week-long trial to find the outstanding Puzzler.

Half of those who entered, failed the first day’s challenges and went home.

On the second day a third of those that remained failed and were forced to drop out.

On the third day a further quarter of the survivors were eliminated.

And on the fourth day a fifth of the remaining challengers failed to make the grade.

What fraction of the original competitors survived past the fourth day.
