Irregular

Very repetitious. Seven cells of nine. Very repetitious. Same pattern many times. When I don’t tell you what song I’m thinking of, and also change the lyrics, I assume it doesn’t make much sense at all.

Doesn’t this grid look like the Tower of Hanoi puzzle? I’m going with that because Fisher-Price seems to market “Rock-a-Stack” under different names around the world, even though I colored the cages and now the pyramid regions look even more like the Fisher-Price rings/donuts.

An Irregular Sudoku grid with a non-contiguous region is possible, but usually there can be only one, else how to determine to which region the errant cells belong? I’ve kept these connected, albeit tenuously, and the resulting shapes seem like botanical pixel art.

It’s so easy to get started. So many dots arranged so carefully. And then… well, this cell, let’s make it orange, and then we need three more orange cells in these three rows, but we also need two green cells in two of those rows, so…

The shapes look a bit like Oklahoma if you’re generous, and because people who illegally rushed in to claim land ahead of the official opening of the legal theft of Oklahoma land in 1889 were labeled “Sooners,” a name the University of Oklahoma adopted for all future sports teams in 1908. I spend all my creativity on the puzzles, leaving nothing for the names.

Some people seem fixated on Inuit people having many words for snow, but English does too! From blizzard to whiteout, with flurries, graupel, and drifts, we have so many words. The one this puzzle’s palindrome lines make me think of is sleet.

I regularly publish 9x9 Sudoku puzzles filled with 3x3 blocks of cells, but this one isn’t regular at all. It’s an Anti-Knight Irregular Sudoku!
