[50 Puzzles Celebration] Double Trouble Entropy
(Published on 30. January 2022, 03:49 by Mad-Tyas)
Thank you everyone for trying, solving, rating and commenting on my puzzles.
To celebrate No. 50 properly, I've combined my two biggest projects, Double Trouble and Entropy, in one puzzle.
It's tricky but completely logically solvable. I hope you enjoy it.
Rules:
Sudoku: Fill every row, column and 3x3 box with the digits 1-9.
Killer: In cages marked with a dashed line digits must not repeat and have to add up to the total given in the top left corner of the cage.
Entropy: The low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) are defined as three different groups. In the finished grid each 2x2 box has to contain at least one digit of each group.
Double Trouble (Entropy Special): If cells of the same group (i.e. {1,2,3}, {4,5,6}, {7,8,9}) are orthogonally adjacent they are Double Trouble cells. If a Double Trouble cell is in a cage it contributes the double value of it's digit to the cage total.
Have fun solving!
Here I've put together a few more of my puzzles that, based on the comments and my personal opinion, are among my best, but haven't gotten that much attention yet:
Double Hidden Inside Squares (killer sudoku with unknown square number cage totals and hidden Double Trouble cells)
Hyperloop (killer sudoku with a hidden loop of Double Trouble cells)
Downtown Dilemma (A special ruleset, that combines hidden Double Trouble cells with skyscrapers.)
Lines of Equality (my first and favorite Equalines puzzle)
The Key (A combination of Double Trouble and Equalines)
Chaotic Sandwiches (entropy sudoku with a modified sandwich ruleset)
X-plosiVe Arrows (standard XV arrow sudoku)
Primetime (prime number based killer sudoku with no given cage totals)
Influencells (my latest new variant)
Solution code: Row 9 followed by column 9 (18 digits)

At one point a third of the way into the solve I found myself saying out loud “this puzzle is f* awesome.” The path you laid out with the ruleset was masterfully done and so satisfying to discover.

Had given up on this twice earlier, but managed to get it right this time. Tough but beautiful, as with your other entropy puzzles! Thanks, @ Mad-Tyas :).
