They had two mathematical variants that piqued my curiosity. One of their variants was with "worms," where extra conditions occurred through regions that didn't have to stay in one column or one row. They also produced variations with sums and products in certain regions. The puzzles maintained a symmetry in the shapes of the regions and in placement of initial clues, and I thought that produced some cool visuals through puzzles. It also led me to wonder about a couple of things:
- What would happen if one kept the usual Sudoku restrictions of one of each character per row and column but dropped the restriction of the 3X3 subgrids? And even more than that, what if there could be repeated characters in the worms, as long as the rule against multiple characters per row or column wasn't violated?
- And these worms....they're friendly, right? So what if two (or more) worms decide to share a square in the 9X9 board?
I plan to post a new puzzle about once a week. Oh, and one more thing: I don't plan to publish solutions. As certain spouses of time lords would say, "Spoilers..."
