Sudoku puzzles (Su Doku)My database includes 3421 puzzles for the moment and I'm constantly generating more.
Rules: Fill in the grid so that every row, every column, and every 2x3 box contains the digits 1 through 6. And you have to solve it in all three axis, x, y and z, according to row/column and box. Put all the boards on top of eachother. Then eg. the first cell in each board should contain all the digits. If you don't understand how it work, ask me.
There is only 1 solution for each puzzle.
