This puzzle was created as a collaboration with ChinStrap for the sudoku adventure series. You can watch Rangsk's solve on YouTube. Tested by my fellow adventure setters (thanks everyone!). Hope you enjoy!
Irregular Schrödinger Sudoku: Place one or two of the digits 0-6 in every cell so that every digit 0-6 appears exactly once in each row, column and bold outlined region. Some cells, called S-cells, will contain 2 digits. For the solution checker, S-cells are ignored.
Region Sum Lines: Blue lines in the grid are Region Sum Lines. Lines are split into segments by region borders. Within each individual line, the sum of the digits on each segment is the same. The sum of segments on different lines may or may not be equal.
Solution code: Column 6, top to bottom - leaving out the S-cell (5 digits).
