Non-consecutive Flower Sudoku

As promised, I’m starting to post the flower sudoku puzzles here. They will be posted usually on Saturday’s.

Today’s puzzle is my first of this kind, it’s a

Non-consecutive Flower Sudoku

for Saturday, February 2, 2008.

Rules: Solve the puzzle so that any two horizontally or vertically adjacent cells DO NOT contain two consecutive numbers (1 and 2, 2 and 3 and so on to 8 and 9). In this layout called “flower” sudoku, there are 5 Sudoku puzzles of standard size 9×9. They heavily overlap each other. In fact, the inner one is fully covered by the remaining 4.

Hint: Use the rule of Twin Nonets in order to solve the puzzle easier.
