If you've never played sudoku before, it's worth a try. You don't need to be good at maths, because maths doesn't come into it. There are lots of places to find out how to play on the internet, but as a quick guide, the objective is to fill a 9 × 9 grid with the digits 1 to 9, so that each column, each row, and each of the nine 3 × 3 sub-grids (highlighted in red on the right) contains all of the digits from 1 to 9 but only once. The gird is partially filled for you to begin with, so you just have to work out the other squares using logic.
However, those numbers could just as easily be a set of nine shapes as opposed to numbers. So, on that basis, do you fancy having a go at a Klingon sudoku?
