Kakuro Puzzle Rules

The rules of Kakuro Puzzles are as follows:

So, what do the rules mean? Well, take a look at the example kakuro above. All the sum totals are given in green squares, and they point in either an across or down direction. The first square in row two contains the number 8. This tells you that the three white squares next to it (an across run of three squares) sum to 8. We know we can use numbers 1-9 only and we cannot repeat a number, so that rules out 2,4,2 for instance as an option, as whilst that sums to eight, it requires us to repeat a 2, which is against the rules. We must use logic and our mathematical knowledge (mental arithmetic) to work out the options for each run of squares, and then cross-reference possible values to gradually make progress and enable us to solve the puzzle.

If you would like a visual explanation of the rules, here is a video outlining the kakuro rules as explained above:
