In the previous post I mentioned SudologiQs. Like Sudoku, the numbers 1-9 apear in every row, column and area exactly once. The difference with a normal sudoku is that no numbers are given as a clue, but that the puzzler gets a number of clues.

Let me give you a small 5×5 example.

Now let’s have an example of what a clue looks like:

Row I: Put the capitols of these countries in alphabetical sequence:
A: Korea
C: Netherlands
D: Afghanistan
E: Germany

All these capitols are well known, though they are not always the biggest cities in those countries:
Seoul, Washington, Amsterdam, Kabul and Berlin.
Assigning their alphabetical sequence: 4 Seoul, 5 Washington, 1 Amsterdam, 3 Kabul, 2 Berlin. So the solution becomes
IA: 4; IB 5; IC: 1; ID: 3; 1E: 2.

OK, let’s get started. Did you know that usage of your memory activates large parts of your brain? I suggest that you try to solve this without using wikipedia.

Row I Put the names of these dogs in alphabetical sequence:
A. A dog who playes basketball
B. Son of Gray Wolf and Kazan

Sudologiq were published in a book in German, by Ludwig Konemann. I have the dutch translation in my possession. Amazon sells a french translation. Googling for a few minutes did not show any english language examples, so you might well be looking at the first example in the english language.

Cross sums

1) Physics*
blank 3x3 square
Every column and row totals 14.
ab3: the atomic number of silver
bc2: the number of hours in a day
bc1: the NGC number of a galaxy in the constellation Pisces
You should need only 2 of the 3 clues.

2) Bible*
blank 3x3 square
Every row and column totals 13.
ab3: the number of years that the people of Israel dwelt in the desert
abc2: number of fish caught by Peter at the end of the gospel of John
bc1: age of Mozes when he was called in the desert, + the number of daughters of Putiel that Eleazer took as his wife(s)
You should need only 2 of the 3 clues.

3) Games*
blank 4x4 square
Use the numbers 2,3, 4 and 6 exactly once in every row and colomn.
ab4: the number of chess pieces at the start of the game
bc3: the number of territories in the risk game
cd1: number of pegs in standard peg solitair
d2: number of suits in a card game
b21: the number of playing squares on a monopoly board MINUS the maximum number of houses on 1 street.
a21: the number of playing fields in back gammon
Again, you don’t need to solve every clue to solve the puzzle.

Cross-sums like the above appeared among others in “Introducing cross-sums” by Edward Fulbrook and Richard Maltby jr, ISBN 0-911104-68-2 in 1977. Mid 2012 I purchased a book with sudoku’s to be solved by obtaining trivia.
The term “cross-sum” is nowadays almost exclusively used for kakuro puzzles, which are hugely popular. Kakuro puzzles have a totally different concept.

In summer 2012 I obtained a book SUDOLOGIQ by Ludwig Konemann, which takes this concept to the form of sudoku’s.
