Tetraddition (6x6)
(Eingestellt am 20. Mai 2021, 00:00 Uhr von Nordy)
Rules:
- Normal 6x6 Sudoku Rules apply.
- Arrows: Digits along arrows must sum to the number in the circle.
- Tetrominoes: All 7 one-sided tetrominoes (Tetris pieces) must be placed in the grid so that the following is true: in a subset of the non-tetromino cells, all six instances of a single digit can be placed (whose value must be determined). For example, after placing all of the tetrominoes, you must be able to place all of the 4s within non-tetromino cells. Six of the non-tetronimo cells have been shaded (dark blue).
Solve on f-puzzles (pre-shaded dark blue)
Solve on f-puzzles (unshaded so you can pick your own colors)
Disclaimer: there may be more than one valid arrangement of tetrominoes, although there is a unique solution code. If ambiguity isn't for you, definitely avoid my previous puzzle.

Lösungscode: Row 3 then Column 5

I don't mind the ambiguity at all, in fact I welcome it, since it is I think cool to obtain something from a non unique arrangement of pieces, or non unique snake or something. however the rules must then be formulated as something like "there exist arrangement/snake...", and I think it is also important that a solver can verify validity of the solution (so it must be possible to find at least on of the possibilities - which is not problem at all in this case). great puzzle btw (and not at all trivial).
Nordy: you are absolutely right about these rules needing a rework, which I will plan to work on soon. Comparing my old puzzles to my new puzzles hopefully reveals an improvement in my rule-writing skills (a very important skill to develop indeed). And thanks for solving some of my older puzzles! You got two of them rated, for which I’m very appreciative :)

Very fun puzzle. I rated it easy even though it took me much longer than expected because I spent the first 30 minutes with 2 of the non-tetronimo squares I needed in the same row (ouch). Once I had the right tetronimo config, the rest was easy. Overall a very fun and smooth solve excluding my initial blunder. Very fun puzzle, highly recommended.

I was a bit to fast so I didn't realise the pentomino in box 1 to be completly in it. Nice puzzle it as fun but took me way longer than exspected.
