just tried the puzzles in the Instruction Booklet - i got another Solution for the very last one, Avergae 9x9 - whats my error? (I marked the differences to the original solution in the Booklet in green)
I 100% convinced myself the 6x6 average was broken. But now looking back I was confusing myself with the double average box - it solves really fast if you use it properly! The pressures of a ticking clock! Thanks for the puzzle set. I enjoyed these!

As sudoku contest over on 7 th please give password for contest puzzles solving
Thanks for organizing and sharing these puzzles. The irregular and converse variants add an interesting layer of complexity compared to standard Sudoku, especially when combined with thematic constraints.
I found that careful candidate tracking and focusing on region interactions helped more than my usual solving approach. The Mahabharat-themed puzzles were particularly engaging and required a good balance of logic and patience.
Looking forward to seeing how other participants approached the tougher grids and what solving techniques they found most effective.
