		ludsan 9 months ago \| parent \| context \| favorite \| on: A new Sudoku layout with 81 uniquely shaped cells I think Sudoku can be very fun to play with new rules, when you begin thinking in higher abstractions. I'm a big fan of anti-knight rules. I look forward everyday to see what new puzzles are out on the Cracking-the-cryptic channel. IMO, your use of the word 'satisfying' is to me the definition of fun!

Negative constraints like anti-knight significantly improve my enjoyment of Sudoku. They make it more likely that puzzles don't devolve to straight Sudoku near the end.
