How to solve a star of six Sudoku? I can do through 5 stars, but can not understand the lack of logic 6?

It is assumed that you connect a number and see if it works through? I am willing to do that, but I do not know if it is considered cheating.

6star do not know about … If the stars are on the difficulty and not the form or something (since they are not 3×3, 4×4 and other regulations and forms), please add that information also. There isn't illogicality. You just have to review the rules … There is always a strategy or trick to find the answer while its logic. And the logic that there is a difference "trial and error," and just put a number and if you work well. If you use trial and error and put a number and see that it is correct, we can say with certainty This number shouldn't be here and eliminate the possibility (sometimes you have to write all the possibilities and use of logic that applies to the rules and to reduce and find correct) As you can tell can you 5stars propably havent tried the real drive (if rates difficulty 5star and 6star and not the form Ignore this), but of course if you put a number to test the waters, is a solution and puzzles shouldn't continue … has to find the error;) as chess, dont move until they "see" This method is useful for situations that the numbers are chained in pairs … color verification method in the tutorial link, but of course you need the possibilities) And while the puzzle has a unique solution, trial and error is not necessary that much BTW any program can use such tricks to solve any sudoku with this method only brute force all numbers as well and can return if it isn't your call trial and error (since there can not its trial and error and its not an acceptable solution software)
