The Sudoku Challenge

Welcome to our special Sudoku challenge! These little logic puzzles are a great way to keep the mind fresh and exercise your powers of reasoning. We’ve prepared a Sudoku puzzle especially for you – do you know where the numbers 1-9 go? Remember: Each number can only appear once in each box and row! Shall we get started?
The name ‘Sudoku’ is Japanese and comes from a phrase ‘sūji wa dokushin ni kagiru’ which means ‘the digits must be single’. Interestingly ‘dokushin’ is the name for an unmarried person in Japan! The name was shortened to ‘Sudoku’ and the craze rapidly took off across the world.
Our interesting facts on each riddle will be fun to read, so take your time. Now let’s get started and see if you are up to the challenge. Completing our riddles won’t be easy, however they are a great workout for your brain. You will need to use logic, common sense, out-of-the-box thinking and your imagination. When awake, your brain produces enough electricity to power a small lightbulb! Your brain is more complex than even the toughest quiz. The human brain is actually composed of around 100 billion total neurons in addition to a trillion glial cells.
