Sudoku Puzzles

Oh my gosh. That is stunning. Looks like DNA unravelling.

Wow!!!! How pretty. Marc must be very talented!!! Thank you!

1. Unique possibilities to 50.Note pair 69 at e68
2. When b6=5,i5=5,d6=7,d5=8,e5=3,e3=4,e7=5,f7=6=e6 and right middle box is devoid of 6.Hence b6=7 and UPs to 81.

Well, it's colourful. I'll say that much!

Very ..very good!! and nice shot as well

11:08 - much easier than yesterday's tough

9:23 - a breeze.

Bet it's beautifully brilliant on a sunny day!

16:44, an easy one but I got mixed up part way through and had to do some of the puzzle again.

I'll have to search this out when I'm next in Sydney and see if it's as stunning when I'm standing in front of it.

I can read the Fitness First sign, but what does the smaller sign on the left say?

There are 2 panels where the Hilton (if it's till called the Hilton!) is, between Pitt and George Streets - at the Pitt St end. In the block between Market & Park Streets. They're very big panels a couple of floors high! I think there is a third one elsewhere in Sydney!

1.Start at 22,basic techniques to UP=81

Alfred, you maybe missed locked 6's at g89,=>i9=9....UP=81
Regards,sotir

I also ran out of UPs at 50 as did Alfred, using SS.

Another great photo Kate.

Hi Sotir.I got i9=9 but could only reach UP 50 never the less.At UP 50,all of rows 1,4,9 and columns a,c are UPs ,as are d3,f6,g2356,h258 and i38.Here I could not find the next UP without resorting to a forcing chain as in my step 2.Regards,Alfred.

5)(6)c4=(6-1)a4=(1-3)b5=c5-(3=8)c7,=>c4< >8.UP=81
Hi MasonD and Alfred,
You are right,need another step;
1.Start at 22,basic techniques to UP=5O
2.(1)d8=d2-(1=6)i2-(6=5)i5-(5=7)b5-b6=d6,=>d8< >7.UP=81
Best regards,sotir

sorry,
ignore first line saying 5)(6)c4=(6-1)a4=(1-3)b5=c5-(3=8)c7,=>c4< >8.UP=81
