Constellation Sudoku

[aman]

My latest Sudoku creation, Constellation Sudoku, was published on the British math educational NRICH website in May:

The same variant was first published as one of the "Puzzles to be solved in Prague -- Good practise" for the Second World Sudoku Championship 2007 on the website

Here is a more difficult puzzle of the same variant which had been withdrawn from the Second World Sudoku Championship 2007 at Prague because of the extraordinary long time required to solve it.

It looks like this sudoku forum turns out to be a joke. If the website owner is interested only in selling his wares, he should do away with this so-called sudoku forum.
