Sudoku Puzzles

Darn! Someone knew I was coming and locked up their rocks! (I'm a rock klepto!)

Good Maen Shiela - You would have a "field day" at my house!

Sure that isn't a wood pile?

Hope someone will explain this one.

"I am a rock, I am an island ..." (a very musical week here). Have a terrific day/night, everyone.

I've heard of a box of rocks, but not barbed wire bunch of rocks....

Getting desperate for pictures?

Hi all, this is a rock fence post. There are many rocks here and settlers used the rocks to make fence posts especially for the corners.

They squared the rocks for fence posts? I see the drill marks for the splitters.

These corner post would save a lot of digging.

Great thanks, Sue

Somebody captured Stonehenge. FREE STONEHENGE! :)

I was looking at it and was wondering what I would do if I was there at that corner.

Hi ttt,

Thanks for your reply to my query/comment on the 14 May Tough. I am OK on finding the bilocation pairs - what escapes me is how to find a good startpoint for an AIC. Best Regards, Neil

This is the same my comment to Steve on his page (not Blog) over one year before :

Hi ttt, Many Thanks - I'm (sort of) glad to know I'm not alone. Best Regards, Neil

A short path:

1)Start 22, basic techniques to UP=30.
( note np:a89=25, c56=25, bh1=39)

2)fc:(6=4)a1-(4)f1=(4-2)f3=(2)i3-(37)hi3=(7)f3-(7=6)f2-(6=9)a2

==>a2<>6. UP=81

A shorter path for second step:

2) (6=4)a1-(4)f1=(4-2)f3=(2)ef1, =>ef1<>6. UP=81

Thanks.
