Good Maen all ~

6:16 interesting Maen

Therapy for Charlie?

A simple proof today:

1) Start 22, Unique Possibilities to (UP) 27.
2) x-wing: 6s at ae2, ae8 forbid e3457=6.
3) c2=1 == c2=4 -- c7=4 == b7=4 -- b7=6 == df7=6 -- e8=6 == e2=6 forbids e2=1. UP 81.

This one must have been easy for a 'tough' -- I didn't need any guesses!

'Charlie's bucket'?

Good Maen to all! So who is Charlie, and why did he forget to take his bucket home from the beach?? Life's little mysteries!

Until someone comes with a better one, here is my proof:
1. Start at 22. UP 27
2. Locked 4s in row 2, elim in Bb2
3. Triple: c8=g8=i8=178, elim in row d9=7, e3=7
4. Locked 8s in Be8, elim in row
5. Xwing: a8,e8,a2,e2=6 => e456<>6
6. Locked 3s in col d, elim in Be2
7. More...

oh, hi Clark, am I too late? :)

Charlie's bucket is one of the Sculptures by the sea (Bondi to Tamarama)

9:32 1 guess, Men all. Have a super weekend.

helo my friends

What the heck is Charlie's Bucket? Good mAen

Another puzzle requiring only one non-native elimination:
1) Start at 22 filled - the given puzzle. Unique Possibilities to 27 filled. (UP 27).
2) a8=6 == a2=6 -- a2=4 == c2=4 -- c7=4 == b7=4 forbids b7=6. UP 81
Sets: 3. Depth 3. Rating .07 - very easy.

23:34...that bucket has seen better days!!

Are the sculptures a permanent display, or is this a temporary exhibition?

Today's tough was easier for me than usual - 0 guesses.

Interesting sculpture!

4:37 that one was really easy

Maybe a reference to charlie and the chocolate factory?

Kewl !!!!

Charlie's Bucket Ha!!! That just doesn't hold water.Looks more like Charlie's got a screw loose.

sorry to ask a silly question but can anybody explain to me the cell co-ordinates used in your comments, i must be missing something

Hi Frank!

Here we use 'chess board' notation:
Bottom left corner is a1, top right corner is i9.
Rows are 1 - 9, bottom to top.
Columns are a - i, left to right.

nic, I am new to this site and the use of forcing chains. In your proof, the first forcing chain eliminated the 1 in a9, but did not seem to lead anywhere else. The second forcing chain broke the puzzle open.

Two silly questions: one, how do you efficiently choose which chain to follow; two, when following a chain, how do you efficiently decide which results to catalouge?
