Each row, column, and 3×3 subgrid must contain all digits from 1 to 9 exactly once. Digits cannot be repeated within any row, column, or 3×3 subgrid.
\n\nEvery clue in the puzzle is wrogn. A clue is wrogn if it is not completely correct.\n\nKiller Cages: Digits in a cage cannot repeat and sum to the digit in the top left corner of the cage.\n\nLook-And-Say Cages: Cages are also, independently, look-and-say. The number in the top left corner also says how many of each digit are in the cage. E.g. there is exactly \"one 1\" in the cages in box 2.\n\nArrows: A digit in a circle with an arrow attached is equal to the sum of the digits on the attached arrow. The different colours don't mean anything different.\n\nRenban: digits on a purple renban line form a non-repeating set of consecutive digits, in any order.\n\nNabner: The set of digits on an orange nabner line must not repeat and no two digits on the line may be consecutive.\n\nGerman whisper: Adjacent digits along a green german whisper line must have a difference of at least 5\n\nKropki dots: Digits separated by a white kropki dot are consecutive, digits separated by a black kropki dot are in a 1:2 ratio.\n\nThermos: Digits along a thermometer must always increase from the bulb to the tip.\n\nThe clues outside the grid are all independently Numbered Rooms, Sandwich and Skyscraper clues.\n\nNumbered Rooms: A clue outside the grid indicates the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.\n\nSandwich: The numbers outside the grid give the sum of the digits between the 1 and the 9 in that row or column.\n\nSkyscrapers: Digits in the grid represent skyscrapers, with their values corresponding to their heights. Taller skyscrapers obscure all shorter skyscrapers behind them. Clues outside the grid indicate the number of skyscrapers that can be seen in that row/column, from the line of sight of the clue."

Each row, column, and 3×3 subgrid must contain all digits from 1 to 9 exactly once. Digits cannot be repeated within any row, column, or 3×3 subgrid.
\nDigits cannot repeat within a cage. Digits along an arrow sum to the digit in its circle. Adjacent digits on a green line differ by 5 or more. Digits on a purple line comprise a set of non-repeating, consecutive digits (in any order)."

\n\nDraw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.\n\nThe loop acts as a German Whispers line (i.e., adjacent digits on the loop must have a difference of at least 5).\n\nLoopy Numbered Rooms: Clues outside the grid indicate the digit which has to be placed in the Nth loop cell in the corresponding direction, where N is the digit next to the clue (and not necessarily on the loop)."

\nYin Yang: Shade some cells so that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. Each 2x2 area of the grid contains shaded and unshaded cells.\nHot/Cold: The value of a shaded cell is one more than it's digit. The value of an unshaded cell is one less than it's digit.\nArrows: Values along an arrow sum to the value in the attached circle.\nKropki: White dots separate cells with consecutive values. Not all dots are given."

"Normal sudoku rules apply\n\nArrows: Values on an arrow sum to the value in the arrow's circle\n\nXV: Values on an X sum to 10. Values on a V sum to 5. Not all XV are necessarily given.\n\nNegators: There are 9 cells in the grid which are negators, one each in every row, column and 3x3 box, containing the digits 1 to 9 once each. Digits in a negator cell count as negative for the purposes of arrows and XV. E.g. a valid arrow could be 8 = 5 + 7 + (-4) if the 4 were in a negator cell."

"- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.\n\n- Index lines: Each turquoise line is an Index Line, i.e. the digit in the Nth cell along such a line (starting from the diamond) indicates the position along the line where the digit N appears. For example, if a diamond cell contains a 3, the third cell along that line must have a 1.\n\n- German Whispers: Adjacent digits along a green line must differ by at least 5.\n\n- Renban: Each purple line must contain a set of consecutive non-repeating digits in any order."

Each row, column, and 3×3 subgrid must contain all digits from 1 to 9 exactly once. Digits cannot be repeated within any row, column, or 3×3 subgrid.
\nEach white line can be divided into one or more segments that each sum to 10.\nEach digit in a shaded cell is less than its orthogonally adjacent neighbors in unshaded cells (as indicated by the inequality symbols)."

Each row, column, and 3×3 subgrid must contain all digits from 1 to 9 exactly once. Digits cannot be repeated within any row, column, or 3×3 subgrid.
\n\nAscending Starters: A clue outside the grid specifies the sum of the first run of ascending digits from the position of the clue (i.e. the sum from the first digit encountered until digits are no longer ascending). This may be only a single digit.\n\nMagic Sigils: Within each 3x3 box, straight magenta line segments have the same sum."

"Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.\n\nNosferatu: Nine cells in the grid are Nosferatu cells. They have to be filled with one complete set of the digits from 1-9. Each row, column and marked 3x3 box contains exactly one Nosferatu cell. \nThere also are nine Prey cells following the same rules as the Nosferatu cells. A cell can only have one of these roles. \nThe values of all Prey cells are 0. The value of a Nosferatu cell is the sum of the digits in the Nosferatu cell and the Prey cell in the same marked 3x3 box.\n\nArrow: The values along an arrow have to add up to the value in the attached circle."

"Normal sudoku rules apply, and all clues are standard. \n\nArrows: Digits along an arrow line sum to the digit in the attached circle.\n\nKiller Cages: Digits in a cage sum to the value indicated in the top left corner, if given. Digits may not repeat in a cage. \n\nPartial Kropki: Digits separated by a white dot are consecutive."

Each row, column, and 3×3 subgrid must contain all digits from 1 to 9 exactly once. Digits cannot be repeated within any row, column, or 3×3 subgrid.
Put the digits 1 to 9 once each into each row, column and 3x3 box.\nShell: Box borders divide the shell (blue line) into segments that add to the same sum. Different segments in the same box sum individually.\nTentacles: Adjacent digits along a tentacle (green line) differ by at least 5.\nFish: The fish (pink line) consists of a set of consecutive, non-repeating digits in some order.\nEyes: Digits on a eye (black dot) are in a 1:2 ratio.\nBubbles: Digits on a bubble (white dot) are consecutive."
