When you come to this forum or another sudoku variants forum, you will find hundreds of sudoku variants to choose from. But with so many, how do you separate the wheat from the chaff? I think a little voting can help to recognize the best variants. And I will start the voting here. I think we should vote to get a Top-10 list. To get enough votes I suggest that every forum participiant gets 10 votes that he can give up to the end of the year for one or more variants. (Of course somebody can use a smaller number of his votes).
So somebody can give all his 10 votes for sudoku X or she can give 6 votes for killer sudoku, 3 for pair pair sudoku, one for zero killer and another one for tricky sudoku. Or he gives all his 10 votes for 10 different variants.
To prevent a discussion what counts as a sudoku variant, you should only vote for variants that are from your point of view sudoku variants. If all make this I think no puzzle format can get the top-10 list that isn't a sudoku variant. To prevent cheating only voters are accepted which have created there account in this forums up to yesterday (14th december 2006).
Note: If you vote for a not so well-known variant and not discussed in this forum or a variant with a name that could be the name for more then one variant (this is for example for all 3-D or cube variants) then give so far as possible please a link to an example or a short descriptiuon of the special rules.
