Here is a new variant of Outside Sudoku puzzles: Sudoku Straights.
The rules of Outside Sudoku are explained here.
The rules of Sudoku Straights are explained here.

Now, all you need to do is combine them and apply them both. It’s a rather difficult puzzle (or so I think).
What do you think?

Outside Sudoku Straights for Friday, March 12, 2010 – Difficulty: IQ.

A while ago I created a computer-generated Hanjie puzzle. I didn’t get much response from you folks, but lets try again.

The rules are same as for your ordinary Hanjies. The only difference is that randomly generated Hanjie puzzles have a random pattern as the solution, it’s not an image of anything (unless your imagination is really inspired).

If you show interest in these I might start posting them more often.

Oh, just to make things clear: The Hanjie puzzles in my book “Picross, Hanjie, Griddlers, Nonograms: 130 puzzles” ARE HAND-MADE.

Picross 30×30 for Monday, March 11, 2010.

So, what’s the verdict?

Here is my second Slitherlink puzzle. My solver thinks it’s rather difficult. What do you think?

The rules of Slitherlink (Takegaki, loop-the-loop, loopies…) can be found in my introductory article.

Killer TriDoku puzzle: all standard rules of Killer Sudoku apply + of course the TriDoku rules.

Has anyone else published this kind of puzzle until now?

Killer TriDoku for Monday, February 22, 2010. Difficulty: BRAIN
(when you click&download the puzzle it won’t look so blury!!!)

The solution is here

If you can have Diagonal Sudoku or Sudoku X puzzles, why not have a TriDoku X? Although it looks more like a TriDoku *, I decided to keep the “X” in the name. Perhaps it could be called a TriDoku Star?

Whatever you call it, I think the additional rules are obvious: in addition to all the triangular nonets, outside and inner edges, hexagons etc., you now have 3 more lines of 9 cells that must follow the no-repeats rule. Those 3 lines are clearly indicated in the puzzle.

And by the way: I switched the dark gray and light gray cells. I think the puzzle looks better this way. Let me know what you think.

TriDoku X for Thursday, February 18, 2010. Difficulty: BRAIN

I’d like to hear more comments from you! I really need to know how you like these puzzles. If you hate them – tell me. Please!

Here is another variant of Outside Sudoku puzzles: a consecutive Sudoku. I’m sure you are aware of the rules, but lets repeat that the numbers in cells that are connected by the pipe “|” symbol MUST BE CONSECUTIVE. Numbers is cell that are have no pipe symbol between them MUST NOT BE CONSECUTIVE, they have to be non-consecutive.
