Sudoku Variations

On this page we show a variety of Sudoku puzzles on a daily basis. The focus will be on Jigsaw Sudoku and Outside Sudoku, but there will also be consecutive, non-consecutive, odd/even, hyper, greater/less than and other Sudoku variants.

We don’t post Killer Sudoku puzzles here – there is a special Daily Killer Sudoku page dedicated for them.

Make sure to also check the Main page of this site, because that’s where occasionally other puzzles are posted: Kakuro, Hanjie (picross, griddlers, nonograms…), Hitori, Nurikabe and more.

Instructions:
1. All standard Sudoku rules apply.
2. If you see an “X” across the puzzle (diagonals) it means that numbers cannot be repeated on those diagonals.
3. In “Hyper Sudoku (Windoku)” puzzles, there are 4 extra “nonets”, marked in light grey. All 4 of them must also contain all numbers 1-9.
4. In “Jigsaw puzzles” puzzles (aka irregular boxes/nonets), the nonets have been transformed from usual 3×3 squares to “jigsaw” nonets. The usual 3×3 boxes do not exist!
5. Jigsaw Windoku puzzles are a mixture of the two puzzle types explained above.
