CrossDigit 2
This teaser is similar to a crossword puzzle, but there is a twist. Instead of words, it uses digits 1-9 and empty (black in crossword puzzles) spaces in a 3 by 3 grid. The grid is arranged as follows:
A1 A2 A3
B1 B2 B3
C1 C2 C3
With the help of the given rules and clues, you have to figure out which box contains which digit.
The rules are:
1: No row can have the same digit appearing more than once.
2: No column can have the same digit appearing more than once.
3: 0 (Zero) is not permissible.
4: Empty spaces cannot contain any digits. They are empty.
And the clues are:
1. The empty spaces are A1 and C3.
2. The sum of digits in row A equal 3.
3. The sum of digits in row B equal 20.
4. The sum of digits in row C equal 10.
5. The sum of digits in column 1 equal 16.
6. The sum of digits in column 2 equal 13.
7. The sum of digits in column 3 equal 4.
Now figure out which box contains which digit and do not forget the rules.

B1 B2 B3
C1 C2 C3

Same rumblings as offered in CrossDigit 1. Only this time it's worse because clues 3 and 4 are both unnecessary.
Sorry. Got wires crossed. Clue 4 only one unnecessary. (I was also working on own version where zeroes were only digit that could be repeated anywhere on grid and that had a unique solution without the use of clues 3 and 4.)
It's a nice intro to these types of problems. And I fail to see the problem with extra information. It just means there is more than one logical path that can get you to the right answer.
It's my belief that extra clues diminish the impact of the tease. As it is we are practically handed the answer. What would it be like if the writer used the sum for the ascending diagonal, the sum for the descending diagonal, the sum of the perimeter, etc. as clues?
you can also use 10 on b1 and 7 on b2,
6 on c1 and 4 on c2
6 on c1 and 4 on c2
haha!!!
sorry, I think I showed the answer, how do you erase comments? I'm new around here, anyway, is my answer correct?
