There are a total of 12 logical dots in this puzzle...

Rubbish - requires complete guesswork based on symmetry.

The 3's in row 1 are column 1-3 and 12 - 15 then everything else falls into place.

Next time please use the test option when creating a puzzle...

Managed with guesswork,.

Thank You.

Totally logical : There's only two possible positions, basing on the corners method, for the first 3 of R1 : beginning in C1 or in C7. If it begins in C7, by testing the consequences of each position of the 4 in C4 with the consequences on R5 and/or R6 and, consequently, on R3, you obtain an impossibility for C3 and C5. So the only position is to begin in C1. By symmetry, the last 3 of R1 ends in C15. After this, you can fulfill R5 and R6. And the rest will come logically to the unique solution.

Pas facile mais logique!

pas mal... pas mal...
