Sudoku Puzzles

Looks like an actor.

10:28 Maen

i am firsty

7:25 with 2 guesses. Who is this guy in the picture???

Getting better on the toughs.

Must be cold there,warm coat and ascot.Stoggie makes him look distinquished.Is that an ipod ear plug?

Dark haired men with well kept beards are very attractive.

geo,

Your were not firsty.
Pardon the spelling ...... chok delee
What's the correct spelling?
Was told this means very crazy.

Looks like my brother-although this fellow comes off a little arrogant, although I cannot for the life of me tell you why I think that!

well a puzzle that could be finished under 15mts.
and no guesses..thats all the more satisfying.
pic of some guy with cigar or something i dunno what..ah yes theres a ear plug,may be from the mobile he has..cant make a guess at this time of the day ....its 10pm and iam off to bed.. bye folks
cheers

Since I have only a little time, the following proof is certain to be improved:

1) Start at 22 filled - the given puzzle. Unique Possibilities to 27. (UP 27).
2a) Hidden pair 48 at g78 forbids g7=169 and g8=458 and g23=4 and g6=8.
2b) a9=3 == a9=6 -- a4=6 == a4=4 -- f4=4 == f7=4 -- More...

have finished all the puzzles in one half hour. now 0315. time for bed as i have work at 730. have a great day

19:19 - a reasonable toughie today.

1) Start 22, UP to 27.
2) Hidden pair 48 at g78 forbids g7=169, g8=1569, g2=4, g3=4, g6=8.
3) g7=8 == g7=4 -- df7=4 == d8=4 -- d6=4 == f4=4 -- a4=4 == a4=6 -- a89=36 == a8=8 forbids g8=8. UP 42.
4) Hidden pair 48 at c23 forbids c3=6, c4=4.
5) c4=9 == b4=9 -- b8=9 == b8=6 -- b13=6 == More...

Only one guess today. Linda, IA. (Except about your brother, never having met him!)

with guesses

I hazard a guess and say the ear piece from a mobile, which he is holding in his left hand and tsking a photo of himself! Nothin wrong with his ego I think!

UN MILLÓN PA QUIEN SEPA DECIR ALGO QUE NO SEA EN INGLÉS!!!

Buenas noches! Como esta? :)

25:49 Fairly straight forward today. Took too long, but worth it eventually. (I think!) I know it's not PC, but nice to see a man with a cigar.

12:44

this is too easy

34:05 very slow :(
beautiful portrait of the modern young gentleman, very elegant European student type. a self portrait?

Steve,

I finally got a chance to look at your proof. There are enough differences between our proofs to allow someone to combine them and come up with something a lot better than either of us wrote.

1) Start 22, UP to 27.
2) Hidden pair 48 at g78 forbids g7=169, g8=1569, g2=4, More...

Baz!

Good work Clark!
Your step 3 is depth 6, but it can easily be pared down to depth 5:
3) g7=8 == g7=4 -- f7=4 == f4=4 -- a4=4 == a4=6 -- a89=6 == a9=3 -- a8=3, a8=36 == a8=8 forbids g8=8. UP 42.
Total sets: 2+5+2+5+2+3+3=20. Max depth 5 twice.
Rating: 3(.03)+ 2(.31) + 2(.07)= .85.
Very nice improvement!

OOPS!
Total sets of Clark's proof: 2+5+1+5+2+3+3= 21. Rating:2(.03)+2(.07) + 2(.31)+.01 = .83.

BTW: Clark's step 3 as a matrix (modified step 3)
g7=8 g7=4
0000 f7=4 f4=4
0000 0000 a4=4 a4=6
0000 0000 0000 a9=6 a9=3
a8=8 0000 0000 a8=6 a8=3
Forbids g8=8
Here, a matrix is more transparent, as it gets rid of the 'broken' chaining.

If one further combines step 2 and More...

I really appreciate the comments from Steve and Clark. I can't follow them all but when I'm stuck they suggest places I should focus oon. Thanks!

07/30/06 poss , 2 guesses - both right

alternative depth 3 proof of 6/13/06 tough:

1) Start with 22
2) UP 27
3) NakedTriple: def5=267 => ~(d6, f4)=27
4) Locked: a987=3 => ~b8=3
5) Locked: a987=8 => ~c87=8
6) Locked: a64=4 => ~c4=4
7) Locked: b64=2 => ~c4=2
8) Locked: g987=4 => ~g32=4
9) More...
