Instructions for solving puzzles

Dear fans of sudoku variants. The variant released on 15th May 2012 was consecutive sudoku and there were players who were a little bit surprised.
Why? Because there weren't any circles between cells which mean consecution.
Surely it was planned because there are many of you who can't use the rule of inversion as often as you could. You can save a lot of time using the rule. By using the rule of inversion it's important to study the given rules carefully. In case of this consecutive sudoku the sentence: "All two adjacent cells that have a small circle between them are consecutive in value" is crucial
If there isn't mentioned that it is about all adjacent cells, you can't use the rule of inversion!

And now have a look how the best of you solved this daily puzzle (15/05/2012). The player with the nick Kwaka:
