Sudoku Puzzles

The Loooooove Boat, soon will be making another run the Love boat, promising something for everyone.....

Now I can't get it out of my head!! Ow, ow, ow!

What is that tan thing in the middle of the pic?

22:48 Maen! Hey, Heidi, you stole my thunder! My head hurts, too... that song will not go away. The only cure is to sidle up to the bar and have Isaac the Bartender pour up a strong one before we pull into Mazatlan...

Glad to be back!! Good to see you all on cruise!!!

Dan - I haven't had a drink in 22 years (had plenty before that!)...but that song running through my head could drive me to it!

16:11 to you all. I hope that your weekend is proving to be enjoyable.

One possible proof:

1) Start at 23, the given puzzle. Unique Possibilities (UP) to 28.
2) fc on 1's: i3 = d3 - d9 = f7, => i7<>1. UP 38.
3a) (hp69)e46, => e46<>5, e7<>9, e89<>69.
3b) (5=9)h8 - (9=8)i7 - (8=4)e7 - (4=5)e9, => e7, ghi9<>5. UP More...

About 20 minutes - stopped timer and forgot to immediately restart when I returned

30 minutes...I new at this

what's good/bad/excellent times

Another path:
1)Start at 23,=>UP=29
2)Coloring (1):f7=f2-d3=i3,=>i7<>1.UP=38
3)fc:(9=4)a7-(4)e7=(4-5)e9=(5)g9-(5=9)h8
=>i7<>9.U P=43
4)fc:(4=6)c3-(6=9)c4-(9=4)b5-(4)b9=(4)a9
=>a23<>4.UP=81

Hi Sotir,

I can only find 5 Unique Possibilities at the beginning of this puzzle: (8)c9, (8)h4, (1)g4, (6)g1 and (7)g7 for UP28, am I missing one?

Hi Dave,

After np ef1=38,we have e2=2
Regards

Will someone please point me to instructions for writing the fairly new proofs? I'm still using this type: (f7=1)==(i7=1) --(i7=3), etc.
