** OCTOBER MONTHLY REWARD - OUT NOW **

The Duality Sudoku Hunt was released yesterday. Massive thanks and kudos to the Sudoku Skunkworks for creating such a brilliant set of puzzles (14 in all). You'll be able to enter the competition if you can solve the first 4 sudokus. If you solve all 14, you'll get a shoutout.

We've also just released Simon & Mark's solve of Vignettes by zetamath, which you can play at the link below:

** TODAY'S PUZZLE **

Mark sends Simon through another of his prank sudokus today with Chameleon's Quantum-safe Sudoku. This is absolutely bonkers. The idea is that you cannot solve it (!) but figuring out how to not solve it is... quite hard!!!

Play this extraordinary "sudoku" at the link below:

https://app.crackingthecryptic.com/su...

Rules:
Normal sudoku rules apply. Cells separated by a black dot must contain digits in a ratio of 1:2 (ie one digit must be double the other). Cells separated by a white dot must contain consecutive digits. Not all possible dots are given. Cages are “Schrödinger cells” ie they contain one of 2 values. After filling all regular cells with digits, all Schrödinger cells must remain unresolved (in other words, both values of every Schrödinger cell must allow for a valid sudoku solution). The quantum balance of the universe is safe with this sudoku. Cats are safe too.

[Note there is a tiny change to the rules above vs those which Simon faced in the video. We used "allow for" rather than "lead to". We do not think this will affect anyone's solve at all but we just thought it might clarify one tiny aspect of the puzzle.]
