Logical Challenge is just what the title suggests – a magazine full of logic problems and IQ teasers. They range from fairly easy to mind-bendingly difficult and if you like testing your brain to the limit, you’ll love this magazine. We include the ever-popular su doku puzzles and a whole section of ‘Mind Bender’ puzzles. There are plenty of the usual grid-style logic problems and also a good selection of non-grid logic puzzles for those who want more of a challenge. A cash competition, full instructions and detailed solutions are also featured in each issue.
