Tetromino flags sudoku

(Published on 24. June 2018, 17:53 by DarkBeamIta)

This puzzle is a 12x12 sudoku that uses digits 1 to 9, then the letters A,B,C.


Every rectangle of this sudoku, except the two "core" rectangles, has been divided in three colored zones, forming a flag, divided in three tetrominos: red, yellow, blue. There are no identical flags (in shape) ignoring rotations / reflections. Each shape can touch a similar one, but no identical colored tetrominos can share one border (only one point eventually).

All the flags are given here (in no order; they haven't been rotated or reflected either).


Every tetromino contains four numbers, that I have summed together. For each rectangle (1 to 10), you have all those sums (in ascending order, not in "spatial" order; but still relative to the correct rectangle); they are written on the right of the sudoku. Too bad, A,B,C have the same value in these sums; zero...

As the normal clues are not enough, to solve the puzzle you also have to reconstruct the correct flag order ;) .

Solution code: Left to right, top to bottom, all the numbers and letters written inside all the BLUE tetrominos; go row by row, not tetromino by tetromino (40 CHARS)

Hi zorant apparently you inverted 5 and 9? ;)

it works... maybe I had a typo when entering the code

@jessica The first code you written is correct. Why doesn't it work :o

@jessica6: No the sums are relative to the correct rectangle, else the puzzle would be unsolvable :)

@DarkBeamIta are the sums corresponding to the location of the rectangle? I.e. are the sums for "1" (10,11,24) valid for the upper left rectangle, as indicated by the upper right schema? Or can the rectangle with the sums (10,11,24) be any of the 10 outer sudoku areas?

german translation:

Löse zuerst das Sudoku mit den Zahlen 1-9 und Buchstaben A-C in jeder Zeile/Spalte/Gebiet.
Lege dann die unten abgebildeten Flaggen auf die äußeren Sudoku-Gebiete 1-10 (wie im Schema oben rechts).
GleichFARBIGE Tetrominos dürfen sich höchstens diagonal berühren.
Die Flaggen dürfen nicht rotiert und nicht gespiegelt werden.
Die Hinweise rechts unten geben für die Flaggen 1-10 die Summe der Zahlen - in aufsteigender Reihenfolge - an, die unter den gelben, roten und blauen Feldern im zugehörigen Sudoku-Gebiet liegen. A,B und C haben hier den Wert 0.

Lösungscode: Für jede Zeile von links nach rechts die Ziffern in den blauen Feldern (40 Ziffern).

@ch1983 True! Now fixed thanks!

One sum of the 6th rectangle seems to be wrong. They don't add up to 45.
