SudoCue - Samurai Contest

Welcome to the daily Samurai Contest. Each day at 00:00 GMT there will be a fresh Samurai Sudoku on this page. If you're a list addict as well as a Sudoku addict, this is the place to be. For each Samurai you have 24 hours (and a night) to submit your solution and gain immortal fame by appearing on the contestants list. The Samurai for the last week can also be found further down the page, but you can no longer submit a solution for them. Version 2.0 and higher of the Clueless Helper gives you access to the last 60 Samurai puzzles. If you want to fight your Samurai addiction, please visit the Samurai Rehab Center.

There are several difficulty levels, but for this contest, you will mostly see tough and hard Samurai. These can be solved with singles, line-box interactions, naked and hidden subsets, X-wing, Swordfish, Jellyfish and Skyscraper.

This is the solution for Samurai number 531, dated 2023-01-25.
