Samurai Saturday 2nd July 2005

Postby grid-lock » Sat Jul 02, 2005 5:35 pm

I cannot complete this.

Large square #1 is giving two solutions for "B", large square #2 gives an answer for "A" but the square is flawed.

The centre square gives two solutions . . . but this doesn't affect "A", "B", "C" or "D".

"D" and "C" are fine.

Anyone else having difficulties?

I only get one solution. It's tedious to solve, though.

Yep, agree 100% with Gridlock. I got as far as cells A and B but didn't bother after that as it was obvious the puzzle's flawed. What a waste of time!

I managed to get a single solution. If it helps, I proceeded through the samurai in the following order. Filled as much as possible in upper-left, then completed upper-right. Went back and completed upper-left. Completed lower-right, then completed lower-left, and completed centre.

Ooh, controversy! Well, either it has a unique solution or it doesn't...

Samurai Su Domu Saturday 2nd July

Thanks for that. I have checked my workings and I made a mistake in the large square #2 on the right which is not flawed but "A" remains the same as before.

However, large square #1 still has two solutions which gives two answers for "B".

It doesn't affect the answers for "A", "B", "C" or "D", but the large centre square also has two solutions.

Overall, I reckon there are 4 different solutions for this Samurai Su Doku.

I got a unique solution - it can certainly be solved. It would be nice to have another fiendish Samurai like the one a couple or so weeks ago... this one took 40 minutes. Similar order to Scrose too.

I agree with Enigma, the Samurai need to become more stimulating rather than simply more time consuming.

I wasn't as quick (50 minutes), but that's the equivalent of just over 10 minutes a puzzle, or not much more than 'mild' on my time scale. It really was a case of routine 'plugging' for the most part.

Again, the puzzle seemed to have a unique solution.

sue, this site offers many puzzles (starting at #70) with 3x3 grids that overlap each other. For solving samurai's, I offered these suggestions, which probably hold true for most sudoku puzzles with overlapping grids.
