Tough Sudoku

Good Maen to all from Ernesto's target!

What a waste of electricity - no wonder California has blackouts! Mind you it does look pretty, but I still say what a waste.

Nice night picture, Keyan. Glenn, where is Winter Springs? East or West Coast? Near Miami?

9:40 Maen

that looks more like a fire picture than yesterday's fire picture.

After embarrassment of 28 8 06 I am hoping I haven't missed anything.
1) Start 23 UP 29
2) hidden pairs 24 at A3 B3 & 78 at H7 I7, naked pair 79 at G6 I6
3) not sure how to express it as a forbidding chain If E4=4 then both C8 & D8 would = 4, therefore E4 cannot = 4, UP81

12:57 with a guess. I love San Francisco, but I'm with Sue--turn off some of those lights! Have a great day/night, everyone.

It's near Orlando.

lovely lights look lots like lava

Very nice Bruce!
Solution to 'tough??????' sudoku of 08 30 06:

1) Start at 23 filled - the given puzzle. Unique Possibilities to 28 filled. (UP 28).
2) fc on 4's: c4 == c8 -- ab9 == e9 forbids e4=4 UP 32
3) Hidden pair 24 at ab3 forbids ab3=1358 UP 81
Sets: 4: Max depth 2. Rating: .06 Does not belong here, methinks!

Gonna have to eat more for lunch, as sudoku did not take up enough time....

Straightforward puzzle today. Much the same as Bruce's. After easy techniques, if f5=7 there's a conflict in Column c therefore f5=9. UP81

Good Maen to all! Agree with both Lizbaby4 and Sue, but hope that Ernesto doesn't play havoc with the power in Florida!

Very easy today. Nothing to brag about. Simple elimination up to the end. The only marginally interesting point could be an elimination of 8 at h1.

We have a1=8 or a2=8 and e1=8 or e2=8. That lives g3=8 or h3=8 or i3=8.

if you think they is bright, you should see vegas some time.... thats sparse lighting for a city. (and heavily blurred)

maeN all!

The brightest lines of lights come from headlights of cars on Market Street. Most of the rest is just street lights and lights in offices and homes, only a small amount of landscape or decorative lighting.(Like the Bay Bridge.)

One guess today.

like lava flows in volcanic eruption, strange city -

This is a time lapse picture so the lights over the course of some period of time are compounded. Any city would look this way if you use really slow shutter speed.

11.55 and close to my best time on the tough
Maen all . . . I loved San Francisco when I was there (got married overlooking the marble steps of the city hall).
Cheers . . .

Looks like it's on fire. Now there's a thought!! lol

8:50

This is a great picture to work as a jigsaw puzzle.

Goodness knows what time that was. Over 20 mins. I didnt find it easy like the guns did. (Too much Kahlua tonight perhaps.)

Done.
