Nice one! I found it easier than 2-stars, probably because I came here after Richard's "Before Nine" version.

It didn't make it less enjoyable. Thanks!

@geronimo92 Always to the side the clue is on.

So 12 <puzzle> 12 could be

9 3 7 6 1 2 5 8 4

@geronimo92 Since we're talking about sums, the reading direction does not really matter.
Take Row 2 for example: start adding up the numbers in the row, and when you get to the number 7, the sum (not including the number 7) should be 29; that's the clue 'before' the row.
In the same row, find the number 5, and wherever it is, add up the numbers that follow it: if the 5 is in Col 7 for example, the numbers after it (in Col 8 and Col 9) should sum to 23, which is the 'after' clue in the given row.

"starting from the 5 without counting it is ok to me" but which direction???? from the outside clue or the normal reading direction

@geronimo The clues on the right side and the bottom side mean that the digits in that row _starting from but not counting the 5 in the diagram_ to this edge of the puzzle add up to this number. The clues on the top and to the left of the diagram mean the digits in this column leading from that edge of the puzzle up to the 7 in the diagram (not counting that 7 itself) add op to this number.

Excuse me I need a precision. When you say following the number 5 in the given row/column, how do we have to read the row/column itself? From the clue or from top to bottom ot left to right? This is not clear to me
sorry
