Puzzle 100, the 'Xtra Sudoku', will change from issue to issue, and will be something outlandish just like the unusual mix of three different Sudoku variants all in one puzzle in the current issue.
But the other puzzles in the magazine will also change too - not all of them, but I'm planning to keep the magazine fresh each month, rather than just repeating new puzzles of the existing types for years on end!
