Thanks for your advice on these puzzles. I've played a few of these at the Croco Puzzle site and have been able to figure out some useful tips. A line of clues like "A ? ? B ?" needs to have A at its first symbol, and the last question mark -- following the B -- cannot stand for B, so it has to be either A or C. A line such as "? ? C" needs to have C as its last symbol. If you have a line such as "B ? C ? ?" the first question mark (in between the B and C) can only be A. Very intriguing puzzle. I wish there were more examples of it avaiable for on-line play. maybe in the near future we'll see it here at Puzzle Picnic.
Greetings and happy New Year to all! The reason for this post is because I need to find help with a logic puzzle known as "ABC Box" or also "ABC Letter Box." We don't have any examples of this puzzle here, but it can be found at crocopuzzle.com and also some external links at Otto Janko's site. The idea is to insert the letters A, B, and C into a square grid, and the lines outside the grid show a pattern of letters with question marks used as variables that can represent any letter. An example might be a 6 x 6 grid with a line showing "? ? B A ?" Because the instructions for these puzzles are usually in German or a language other than English I just can't figure out exactly how to insert the correct letters! Any help that anyone can offer regarding this puzzle I would greatly appreciate! This might be a fun puzzle to add in the future here at Puzzle Picnic! Thanks!
By the way, Brainbashers is an excellent logic puzzle site featuring puzzles such as hitori, futoshiki, light up (akari), ABC path, and many more. The Brainbashers site also features many intriguing games and puzzles of all kinds, one of my favorites being Number Master, which is like playing the well-known board game MasterMind with numbers instead of colored pegs. Brainbashers has featured some Spokes puzzles borrowed from here at puzzlepicnic with the author's approval. Check it out!

Here is another intriguing puzzle that would be fun to see here. This puzzle is Kakurasu. It can be played on-line at the following site:

http://www.brainbashers.com/kakurasu.asp

This puzzle can be quite intriguing, especially when playing the higher levels, from about 6 by 6 on up.
Here's a link to a site that offers both Killer Sudoku and Greater Than Sudoku puzzles.

http://www.killersudokuonline.com
Another puzzle type I'd like to see here at Puzzle Picnic is Greater Than Sudoku, also known as Comparison Sudoku. In these puzzles the inequality symbols that are characteristic of futoshiki puzzles are used here. Most often these puzzles are blank grids with inequality symbols used between each square within the 9 by 9 "boxes" that are part of a sudoku grid. Inequality symbols can also overlap the lines between two boxes. These puzzles, especially the ones with blank grids, can be quite challenging! Please feel free to share your thoughts on greater than sudoku puzzles.
Here's a puzzle type which I found at the German Puzzlewiki site. The German name for this puzzle is "Diamantensuche," which roughly translates to "Diamonds" (not the Diamonds puzzle here, which are much like Minesweeper). An English name for this puzzle could be "Diamonds and Arrows." You have a square grid with some empty squares and some containing arrows pointing in any one of eight possible directions.
There are diamonds hidden in the grid and the object is to locate them. No 2 diamonds may be adjacent to each other, not even diagonally. Each arrow points to only one diamond though not all diamonds will have arrows pointing to them. Numbers above the columns and to the left of the rows show how many diamonds, if any, are in a particular row or column.

At the Links page here click on Logic-Masters, then Puzzlewiki, and then "Mystery List" and "diamantensuche/de"

By the way, I think the puzzle anurag.sahay is referring to is called "Piecework" in various puzzle books and is also known by the Japanese name "kedoku." Here are 2 puzzle books that include this type of puzzle:

The Mammoth Book of Kakuro, Wordoku, and Super Sudoku (the name "kedoku" is used here)

Japanese Number Puzzles (here this puzzle is called "Piecework").

Here's a suggestion for a new puzzle type at Puzzle Picnic. How about adding Spotlight puzzles? These are available at the Otto Janko site. You have a grid of numbered arrows. The arrows represent lights, some of which are turned on (white) while others remain turned off. (black) When an arrow is white its number shows how many other white arrows it is pointing to. I've played quite a few of these. they are challenging but it's also very rewarding to successfully solve the puzzles! Let me know what you think. also, I'd love to see more Thermometers puzzles added here in the near future.
Thanks for posting these Thermometers puzzles Johan! I've seen this kind of puzzle described before, but this was my first opportunity to try solving any of these. I think the secret lies in using the "trial and error" method to explore certain possibilities, and then these options can be ruled out once you reach a contradiction, such as having 3 filled sections in a line that can only have 2. I hope to see more of these intriguing puzzles!
Sorry, but I just can't get this to display right and I'm too tired to try any more tonight. I just can't figure out exactly how to use the Code brackets.
My suggestion for anyone interested in the kind of puzzle I've been trying to display here is go to Google and search for "arithmetical restoration puzzles." The famous English puzzlemaster H. E. Dudeney referred to these as "skeleton puzzles" in his book 536 Puzzles & Curious Problems.
OK Another try.

I see that the diagram did not display correctly. I have scanned this puzzle from a book on mathematical puzzles, so if anyone wants I
can e-mail you the image.
Here is a puzzle very similar to alphametics. These puzzles are known as "arithmetical restoration puzzles" and have been around for a very long time. They are a bit more challenging because all missing digits are simply replaced by X's, asterisks, question marks, or blank lines. Here is an example:

x 7 x
_________
x x ) x x x x x
x 7 7
_____
x 7 x
x 7 x
_____
x x
x x
___
0

The problem is restore the missing digits, all of which have been replaced by X's, and thus reconstruct the original division. Here are 2 pieces of information that will help you. 1. All the 7's are given. 2. The three-digit
partial product ending in two 7's is divisible by 3, and maybe even by 9.
You might find it helpful to copy down the diagram on paper instead of printing it. Happy solving.
