How to play KenKen:

Fill in the squares such that each row and column has 1 to 6 uniquely..
Each coloured 'cage' contains a clue.

For X+ (plus) symbols the numbers that fit in that cage add up to X.
Where the clue number is assoicated with a '-' (minus) the cage contains two numbers, one of which is X less than the other. For example, 2- means that the cage contains 1 and 3, 2 and 4, 3 and 4 or 4 and 6, since these are two numbers apart.
When the symbol is 'x' (multiply) all the cage solutions when multiplied sum to that clue number.
And lastly, the '÷' symbol means the two numbers in that cage are divisible by that clue number.
