Ok now I actually did research on this,the minimun number of clues neccesary to generate a "unique" solution is 17, anything less ie 16 or what not will not allow for a unique solution per puzzle.

I have found a sudoku 6*6 with exactly 8 clues which has an unique solution.

here is the sudoku:

040 | 003

000 | 060

------------

000 | 004

006 | 002

------------

030 | 010

000 | 000

-------------

I wonder if an other person has found less clues than me for a 6*6 sudoku.

I can say that the minimum number of clues for a 6*6 sudoku is inferior or egal to 8.
