Wacky Sudokus
In case you can't tell, weird sudoku variants are a personal favourite of mine. They have both been very enjoyable to make, but also rewarding in seeing the feedback and interest received.
I know a lot of people on this site are fans of the youtube channel Cracking the Cryptic, where many such wacky sudokus have been seen before
Wacky sudokus are sudokus that use rules or concepts that have yet to be seen before, or are very uncommon. They can pretty much involve anything, as long as it is not a normal sudoku.
Here are some examples of such wacky sudokus:
- Sudoku like you've never seen it before
- Self-referential Sudoku
- Ever heard of a W-Sudoku?
- Sudoku in the third dimension (3D Sudoku)
I think this would be a fun topic to see what the community can come up with!
