Sudoku Puzzles

But what IS the speed limit???

1. Unique possibilities to 39.
2. If e6=5,e2=7=h5,i2=6=e5,i6=2;i5 has no candidate.So e6=2.UP81.

1) Basics to UP 40. Note pair 89 in cf2.
2) i5 cannot be 7. If it were, then h2=7, and also h5=e6=5, and no legal alternatives remain form e2.
So h5=7. UP 41.
3) h2 cannot be 5. If it were, then g2=4, i2=6, and both 5 and 6 of the middle right box would have to go into g4. So h2=4. UP More...

Meanwhile Alfred posted a cleaner solution. Well done! Other than I did get to UP 40 (h1=9?)

Have a great day/night everyone!

Knew this was Sue's as soon as I saw the symbol.

So ........... hold onto your scalp!

maen all! hard to believe that all of oklahoma was a vast reservation until the land grab of 1880 from which the state gets it's nickname "sooner" because so many settlers "jumped the gun" in the homesteading rush...i've always found the speed limits on the great "rez" More...

Speed limits must consist of unique possibilities to 39. Anything over must surely be a unique hope for the best.

Best of all, unique across the reservation without getting noticed.

Good day/night !!!

Good day all.
just less than 41 min

1)start at 22,basic techniques to UP=40
2)(2=67)i25-(7)i3=e3-(7=5)e2-(5=2)e6,=>i6<>2.UP=81

Hi Jyrki, Sotir and All,

Jyrki - Both Sotir and I got to UP=40 on this one.
Sotir, I have posted a Eureka solution for yesterday's Tough (and hope it's OK), in response to your comment yesterday.

Best regards, Neil

Hi Neil,
My yesterday comment was for dec,29/09,that I found
extremely difficult using Eureka Notation.
Your yesterday solution was very nice.

Hi Sotir,

It must have been the tuition that you have been giving me. Many thanks and best regards, Neil
PS: I am still working on Dec 29, and will keep you posted.

Wish all of you a very Happy New Year and a belated one for those who have already seen the new year in.
