The "365 Brain Puzzlers" 2025 Calendar by Mensa, edited by Fraser Simpson, is the perfect daily challenge for those who love to stretch their mental muscles. With a new puzzle each day, this calendar is packed with brain teasers ranging from crosswords and logic puzzles to math games and word problems, ensuring a year full of stimulating fun. The puzzles are designed to improve cognitive skills and provide a great way to start each day with a mental workout.

For example, the puzzle for November 7, 2025, called "Split Ends," challenges solvers to complete a crossword using the first and last letters of each word with clues provided to fill in the central letters. Meanwhile, the puzzle for September 24, 2025, called "Scoreboard," asks participants to reconstruct a soccer league table and the scores of six games using partial information and logic. These engaging tasks not only entertain but also hone problem-solving and critical-thinking skills.

Engaging in such brain puzzles is not just about fun—scientific studies have shown that regular mental exercise can help keep the brain sharp and slow cognitive decline. Did you know that the concept of Mensa was formed at a meeting at Lincoln College, Oxford, in 1946?
