How about this ... (forgive me if its already been done) ... 25 5x5 grids each containing the letters of the alphabet, except 1 (i.e. A-Y) Same rules as Sudoku, except add this into the equation. Whatever letter is left out of a grid must be used in all of the other grids. In other words if grid 1 contains A-Y then Grids 2 - 25 must contain Z. This rule may make the puzzle unsolvable ... the math on this is making my head spin ... have I created a monster? _________________ If you are leading and no one is following, you are only taking a long walk.

If each row and column has this rule as well, then it would be a bit easier. This will also mean that 1 letter is in every grid - maybe this could be the letter that you have to give as the puzzle "soluution key" instead of typing the whole bloody thing out.

Each row and each column would have the same rule as each 5x5 grid. Although single letter could be the solution key, it would still be quite difficult. _________________ If you are leading and no one is following, you are only taking a long walk.

Some cells contain two digits, and those are marked. The same puzzle where the two-digit cells didn't get marked would probably be much more difficult than a regular Sudoku puzzle. Maybe something like that? Back to top TMD Joined: 19 Oct 2005 Posts: 5 : Items Posted: Mon Oct 24, 2005 7:02 pm    Post subject: What a great link. With all of the variants described, my variant is really nothing more than that ... a variant. But what a variant! _________________ If you are leading and no one is following, you are only taking a long walk.
