Tricky sudoku (Posted on 2006-06-05) Difficulty: 4 of 5
A new version of Sudoku Puzzle.

In this version, like in a normal sudoku, numbers 1 to 9 appears only once in every row or column. But in the nine 3 X 3 subblocks any number, instead of appearing only once, appears either once or twice or not at all. In each subblock, three numbers appears once, three numbers appears twice & three numbers do not appear at all.

Considering this rule solve the sudoku puzzle given below.

+---+---+---++---+---+---++---+---+---+
| 1 |   | 6 ||   | 7 |   || 2 |   | 8 |
+---+---+---++---+---+---++---+---+---+
|   | 1 |   || 7 |   | 2 ||   | 9 | 3 |
+---+---+---++---+---+---++---+---+---+
|   | 7 |   ||   |   | 4 ||   |   |   |
+===+===+===++===+===+===++===+===+===+
|   | 8 | 9 || 1 |   | 6 ||   |   | 2 |
+---+---+---++---+---+---++---+---+---+
| 5 |   |   || 3 |   |   ||   | 1 |   |
+---+---+---++---+---+---++---+---+---+
| 8 |   | 3 ||   |   | 7 ||   |   | 9 |
+===+===+===++===+===+===++===+===+===+
|   | 6 |   ||   | 9 |   || 8 | 3 |   |
+---+---+---++---+---+---++---+---+---+
| 2 |   | 1 ||   |   | 5 ||   |   | 7 |
+---+---+---++---+---+---++---+---+---+
| 9 |   |   || 8 |   | 3 ||   |   | 4 |
+---+---+---++---+---+---++---+---+---+
