Sudoku Variants are back!

Also, as a special gift and to make it up to you, I have prepared a brand new variant – Jigsaw TriDoku.
I think the puzzle is self-explanatory. It is a hybrid between Jigsaw Sudoku and TriDoku. Make sure to use the hexagon rule which can be found in the TriDoku introductory article.

Other TriDoku puzzles can be found in this category.

And finally, here is the puzzle.

TriDoku for Monday, August 30, 2010. Difficulty: THINKER

Comments? Questions? Please!

This should be a tough one – perhaps too tough? It’s only rated “BRAIN”, but the layout makes it quite difficult, I think.

5 overlapping Jigsaw Sudoku puzzles put together in the Flower (Gattai-5) layout, which is similar to Samurai Sudoku but not exactly the same. Make sure to use the “twin nonets” solving technique, otherwise you won’t get too far.

Flower Jigsaw Sudoku for Monday, April 26, 2010 – Difficulty: BRAIN.

Today’s puzzle on the Daily Sudoku page is somewhat ambiguous. This is why I’m duplicating it here on the main page.

Basically, it’s a Classic and Jigsaw Sudoku combination. In addition to 9 Jigsaw nonets, there are 9 classic Sudoku nonets too. You have to use them both in order to solve the puzzle. Since it’s first of its kind, it’s rather easy, but give it a go to see how you like them.

By the way, a few of these can be found in the Jigsaw Sudoku book volume 2.

It’s been a while since I last posted a Samurai Sudoku variant puzzle. Here is a new one. As far as I remember, I never posted such puzzle before.

Remember: shaded cells MUST contain only ODD numbers!

Another novelty in 2010 – Outside Jigsaw Sudoku. Read the rules of Outside Sudoku first. And then, twist it a little – it’s a Jigsaw (Irregular) Sudoku puzzle!

UPDATE: One clarification about the rules of Outside Jigsaw Sudokus: The clues tell you which numbers appear in the 3 closest cells in that row/column. They are not linked to (jigsaw) nonets. Oh, and I’ve posted the solution.

Here is a Christmas gift for you! Just in time for the holiday season, three new books have been published on Amazon:
