Figure Sudoku No. 1 and 2

Postby Pyrrhon » Tue Jan 16, 2007 10:50 am

We spoke in another thread about crossovers between figure sudoku and skyscraper. Possibly figure sudoku are not so well-known. So I'm giving an own puzzle of this variant. I guess that inventor of this variant is Vladimir Portugalov. He used letters. They can be repeated. But here are the rules for my puzzle:

Fill the grid with the digits 1 to 9. Each row, column and 3x3-box has exactly one of each digit. All occurrences of each shape outlined in black (rotated and/or mirrored) must contain the same set of digits (possibly in different orders). None shape contains a repeated digit.

Nize puzzle, requiring a lot of innovative logic. I had to use T&E a couple of times, though, reflecting either my lack of sophistication or my wish to have variants not also be killers.

But a couple of T&Es (for a person who refuses to use advanced techniques) is not bad at all. Thanks again!

Very nice! I like the figure deductions and eliminations.
Got any more?:)

There is a figure skyscraper sudoku in the skyscraper discussion and another figure sudoku at the forsmarts page.
