Entrothermia 6
(Eingestellt am 12. Juli 2026, 18:35 Uhr von fractalminding)
Normal sudoku rules apply. Each 2x2 box in a grid has contain low digit {1,2,3}, middle digit {4,5,6} and high digit {7,8,9}. Digits along each thermometer must strictly increase from the bulb end. The sum of all digits inside each thermometer must equal 24.
Creating this visual layout required immense work to ensure a completely logical path. If you feel there are no beautiful logical steps left, please do not use bifurcation or rate the puzzle low.I am ready to help everyone personally. Write a comment or message me with a screenshot (e-mail in my profile), and I will explain the next step.If you find all the logical chains and enjoy the puzzle, a short comment from you would make my day. Thank you!

The first part of filling in the thermometers using the global entropy rule was very nice. The last part was a lot harder yet satisfying.

I tried to send you an email with a screenshot but it was rejected :/ I'm quite stuck, I have a single digit

God bless you for 3-digit solution code.
With this series I always struggle to assign proper difficulty. Some parts are simple while others are very hard to crack. I see it’s because of minimalism. Overall I like the series a lot.

Hahah.. I glad you appreciated 3-digit code. I plan to continue this practice. As you correctly noted, minimalism is my key goal. But I only publish sudokus that I like about solving process. I have almost no control over the difficulty. Despite all this, there are people who like it. Thank you!

Another beautiful Entrothermia puzzle! My solve time suggests a 3* rating for this one. The global entropy is still quite difficult to spot sometimes but your series did a really good job teaching me. Thanks a lot for sharing and please continue the series if possible!

I am glad you have learned something new! I will surely publish the new part when i find a cool construction. Thank you for you kind words.

This was a tough nut to crack, definitely deserved 4*. You are right, it is possible with logic only, but sometimes the path is quite tricky to spot. I really liked the early game, the thermos worked so nicely together. I would a love a 2* in the future using this early game with an easier endgame. Overall, still a very fun puzzle to solve, thank you for setting!

I think you're right. It makes sense to make sudokus with a smoother solving. But within the framework of the concept of absolute minimalism, this is not so simple. Thanks for the feedback!

Very interesting how the global entropy helps fully resolve the thermos. I'll probably take a look at the earlier puzzles in the series as well :)

It's very nice to hear that. I hope the other sudokus in this series will also interest you.
