Finland-based mathematician Arto Inkala has created a sudoku to rival his world’s hardest ‘Al Escargot’ puzzle of 2010.

With the average newspaper sudoku rated at five stars of difficulty, this monster puzzle tips the scale at an 11-star-difficulty rating.

Hosted on the Efamol website, Inkala’s sudoku challenge, along with the illusive answers, are ready and waiting for those brain-fit individuals looking to stretch their brainpower with the ultimate in mental challenges.

Made up of 100 billion nerve cells, our brains are the hub of our nervous system and an amazing feat of evolution.

But with expert medical opinion claiming that brain deterioration can set in as early as 18 years of age, it is vital to keep the brain active, and ensure we are stocked up on essential nutrients to stave off degenerative brain diseases.

Recent studies have shown that engaging the mind in puzzles could have a dramatic effect on reducing the build-up of harmful proteins in the brain which can lead to memory loss and confusion, typical of Alzheimer’s.

Scientists have attributed modern man’s superior brain development to the high Omega-3 fatty acid diets of our ancestors. Comprised of approximately 60 per cent fat, our brains need a good supply of essential fatty acids – in particular Omega-3 and Omega-6 – to maintain learning ability, concentration and co-ordination.

So give the world’s hardest sudoku a go.
