The New Sudoku Players' Forum

I found the site puzzlemadness.co.uk and it offers a good amount of a variety of Sudoku puzzles. However, the difficulty:hard Killer Sudoku puzzles on both 16 and 18 June 2023 were, for me, quite challenging. Is it possible that I am missing some technique that makes these more readily solvable? Yes, I know that the squares, rows, and columns need to add to 45 and that multiples of them need to add up to 45x as well.
