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.
