Need 50 easy, 50 medium and 50 hard Puzzles

VIDEN

I am now pretty much finished with my first stable working Version of my Sudoku game. Of course there always are things to optimize but so far its okay.

Actually I wanted to implement an own Generator.
But if I want one with different difficulties (which is what I do want!) I will have to implement different solving techniques like naked Singles, hidden Singles ect. in my solver and in the moment I'm just using a backtracking one.
I started off with the naked and hidden Singles which are quite easy but since I will have to go to university from December to March I wan't to have a stable, working release till the end of November.
So I descidet to use a puzzle DataBase for now and maybe work on the Generator/ logical Solver later.

I am using 3 *.txt-Files as data base:
EasyPuzzles.txt / MediumPuzzles.txt / HardPuzzles.txt
The Puzzles are saved in lines like:
000306500800500000010000040900080020000000000040060001050000010000009002006108000
and then read out by my "Generator" class.

Well everything is working, the only problem is I don't have any puzzles Wink

of course I could just surf through the Internet and steal puzzles, but thats not what I want to do!
So if somone would be so kind and provide me with 50 easy, 50 medium and 50 hard puzzles from his/her own Generater I would be really thankful.
Oh, and my Program does not show candidates so coloring, and XY-Wings and things whith similar difficulty will propably even be too hard for the hard ones.

Hello all I was wondering if anyone could extend me the same favor as Viden asked for, a small library of around 50 sample easy, medium and hard Sudoku in the usual format.
Unfortunately i haven't had time to produce a working generator for Problems, but my solver seems to work correctly!

Thanks in Advance!

Thanks for the Suggestions Pat..

I have since derived a small library of puzzles fitting my requirements..

To answer your Question.. yes i would call those sudoku puzzles listed as hard puzzles, however my Solver is very basic, implementing only a few techniques for solving.

Thanks Again
