Learn the Alphabet: Q is for Quadruples

(Published on 5. November 2022, 15:00 by Crusader175)

My idea for this series is to make 26 puzzles with different constraint that start with each alphabet (A-Z).

Rules:

Normal sudoku rules apply. Digits in a white circle must appear somewhere in the four cells surrounding that circle. If a digit appears twice in a white circle, it must appear twice in the four surrounding cells.

Such a cool puzzle! At so many points I went, "no way that this puzzle uniquely resolves, right?" and kept being surprised and delighted :)

Reply: Thank you dennischen! I'm glad you like the puzzle.

Gah! I had a fundamental flaw in my logic, that I didn't catch until the 4th time I restarted the puzzle. But once I found my flaw, the puzzle solved quite nicely. Thanks!

Reply: I'm sorry to hear you have trouble solving it, hope you still have fun. :)
