# SudologiQs

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
B: USA
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
C. Laura Ingalls’ second dog in Little House on the Prairie
D. fictional collie dog character created by Eric Knight

Row III Link these quotes with the persons
A. Only two things are infinite, the universe and human stupidity, and I’m not sure about the former.
B. Faith is taking the first step even when you don’t see the whole staircase.
C. Blood, sweat, toil and tears
D. By all means, marry. If you get a good wife, you’ll become happy; if you get a bad one, you’ll become a philosopher.
E. Love is a fruit in season at all times, and within reach of every hand

Column D In which country do you eat this?

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*

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*

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*

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.
