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.
The grid is covered with fog. Placing correct digits will reveal the fog around that digit. Guessing is not required! A digit in a red circle indicates exactly how many red circles contain that digit. Additionally, a digit in a red circle must reappear at least once in its 8 surrounding cells. The two given circles contain the same digit. Digits along a purple arrow sum to the value in the attached circle. Red circles may or may not have arrows attached. Arrows do not share cells and do not cross."

Each row, column, and 2×3 subgrid must contain all digits from 1 to 6 exactly once. Digits cannot be repeated within any row, column, or 2×3 subgrid.
Orthogonally adjacent digits cannot be consecutive. Digits along a line form a set of non-repeating, consecutive digits in any order. The sum of the digits along a diagonal, indicated by an arrow, sum to X, where X must be determined and is the same sum for all arrows."

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.
Digits must not repeat on the marked diagonal. Digits in cages must sum to the cage total. Each N-sum line can be divided into two or more non-overlapping groups of adjacent digits that sum to N. No two lines have the same value for N."

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\nThere are nine doubler and nine halver cells in the grid. Place one doubler and one halver in every row, column and box such that doublers and halvers cannot share a cell, and each digit from 1-9 appears once in a doubler cell and once in a halver cell. A doubler cell's value counts as double its digit while a halver cell's value counts as half its digit.\n\nValues on a grey palindrome line read the same forwards and backwards.\n\nBox borders divide each blue line into segments whose values have the same sum.\n\nEach inequality symbol points to the smaller value of the two cells on either side of it."

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.
Place every digit from 1 to 9, once each, into every row, column, and 3x3 region.\n\nHot arrows: An orange arrow points toward a cell N distance away that has a value greater than N, where N is the digit in the arrow's cell. (For example, if r1c2 is 5, then r6c2 is greater than 5.)\n\nCold arrows: A blue arrow points toward a cell N distance away that has a value less than N, where N is the digit in the arrow's cell. (For example, if r9c8 is 5, then r4c8 is less than 5.)\n\nDiagonal: Digits may not repeat along the blue diagonal."

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.
On a blue thermometer, the even digits strictly increase from the bulb end, and likewise for odd digits on an orange thermometer. Digits of the unrestricted parity can occur anywhere and in any order on a thermometer, as long as the thermometer is strictly dominated by digits of the restricted parity, e.g. a 4 cell orange thermometer must have at least 3 odd digits."

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.
Digits in killer cages cannot repeat. Each killer cage represents a skyscraper with a height equal to its sum. Digits outside cages do not have any skyscrapers. Clues outside the grid indicate how many skyscrapers it can see from that direction. For example, if there are 5 killer cages in a row or column, and their sums are 4, 10, 10, 13, and 5, leading away from a skyscraper clue, the skyscraper clue's value would be 3."

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\nCells separated by a white dot are consecutive. Cells separated by a black dot are in a 1:2 ratio.\n\nDigits in cages can't repeat and sum to the indicated total. However, one of the digits from 1-9 is an imposter. Whenever that digit appears in a cage, it counts as any value from 1-9 towards the cage total. This value can be different for each cage that the imposter appears in."

Draw 12 orthogonally connected regions of different sizes which do not overlap. The regions do not need to cover the entire grid.\nWithin a region, a digit may only repeat if it appears on a gold ring, in which case it can only appear on gold rings. A digit on a gold ring indicates the number of gold rings within its region. \nA digit on a pear tree is equal to the number of cells in its region.\nThe 3 digits on red baubles sum to 25."

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.
The grid is partially covered in fog. Correctly placed digits will clear the fog around that cell. No guessing is required. Digits in a circle must appear within the four surrounding cells. Draw a single one-cell-wide snake of orthogonally connected cells which begins and ends in Box 4. The snake can touch itself orthogonally and diagonally but must not branch or overlap. Box 'N' must contain 'N' amount of snake cells, and within this Box \u2018N' the digit 'N' must appear on the snake. (Boxes are numbered in normal reading order.) Eg Box 5 must contain exactly 5 snake cells, and one of these snake cells must be the digit 5. Box borders divide the snake into segments which sum to either 1, 5, 10, 15 or 20. Cells which are not part of the snake must be able to orthogonally connect to the grid boundary."

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.
Each purple line is divided into discrete sections, each of which consist of one digit (a \u2018total'), followed by more than one digit summing to that total. The ordering of \u2018total' and \u2018sum' will be consistent on each line. The solver must determine which end of a line starts with a total."

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.
Along thermometers, values strictly increase from the bulb end. There are nine doubler cells in the grid, one in every row, column and box. Each digit from 1-9 appears in a doubler cell exactly once. A doubler cell's value counts as double its digit. "
