Rätsel Siebenkampf
(Published on 29. September 2016, 22:00 by moss)
Sudoku: Place the digits from 1 to 6 in every row, column and 2x3-block.
Battleships: Place one ship of length 3, two ships of length 2, and three ships of length 1 into the grid, so that ships do not touch, not even diagonally. Numbers outside the grid indicate the number of ship segments in the adjacent row or column. In this puzzle, the ship tiles count as blackened cells.
Yin-Yang: Blacken some cells, such that all cells sharing a colour (black and white) are orthogonally connected and no 2x2-region in monochromatic. One black cell is given.
Polyominoes: Blacken some cells. Then dissect the blackened cells into different (connected) polyominoes of size at most four cells. Cells separated by a black line cannot belong to the same polyominoe. Mirrored or rotated polyominoes count as the same polyominoe.
Coral: Blacken some cells, such that all balck cells are connected orthogonally and no 2x2-region is completely black. All white regions have to be connected to the border of the grid. The numbers outside the grid indicate the lengths of all sequences of black cells in the corresponding row or column. A ? indicates a block of unknown length.
S-puzzle: Blacken some cells, such that the blach cells can be decomposed into exactly 6 S-tetrominoes. These tetrominoes can be rotated and mirrored.
Tapa: Blacken some empty cells in a way that all black cells are connected orthogonally and no 2x2-region is completely black. The numbers in the cells indicate the lengths of all blocks of connected black cells surrounding it. Some of the numbers are replaced by ?.
Solution code: First the number of black squares for each row from top to bottom for the battle ships, the yin-yang, the tapa, and the corral. Then the number of different polyominoes in each row from top to bottom for the polyominoes puzzle and the s-puzzle. Then the 4th column of the sudoku. (42 numbers in total)

Na endlich. Die Anzahl der Versuche, die in Widersprüchen endeten, ist Legion.

Wunderschön! Vielen Dank dafür. Ich war auf der Suche nach einer ähnlichen Herausforderung wie die Roundabouts und bin mehr als glücklich über diese Entdeckung.

Das Rätsel hat seinen Reiz durch die ständige Interaktion mit dem zentralen Sudoku, super.

Was ist ein Polyomino? Hat es eine mindestanzahl von Feldern?
@akodi: Was dieses Rätsel angeht sind 9 Polyominos relevant: 5 Tetrominos ILOST; 2 Triominos; 1Domino und 1 Monomino (ein Feld)

Sind denn S und N verschiedene Tetrominos? Bzw. gibt es 5 oder 7 Tetrominos?

Die Idee mit den Zahlen als Anzahl Schwarzfelder ist wirklich gut (und für mich neu). Und die Ausführung ist auch klasse, und ganz schön schwer.
