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 the indicated diagonal, digits do not repeat. Black dots indicate that cells are in a 2:1 ratio. Numbers outside the grid indicate the sum of the cells in the direction of the arrow. In cages, the number in the top left denotes the sum of the cells in that cage. Digits cannot repeat in cages. A given cage can only contain prime numbers, or it can only contain non-prime numbers. For instance, a single cage can contain 2,3,7, since they are all prime, but it cannot contain 1,2,3,7 since 1 is not prime but 2,3,7 are prime. "

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.
A clue outside the grid indicates the value of the sum of all even or all odd digits on the indicated diagonal. If the even digits are counted, no odd digit contributes to the sum and vice versa. Digits in a cage do not repeat, and the clue in a cage indicates the sum of all even digits or of all odd digits which are contained in that cage."

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 every row, column and 3x3 box.\nFog: The grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells.\nSplit-Pea Lines: The sum of the digits on a line strictly between two circles is equal to a concatenation of the two values in the circles, in some order. For instance, 4-347-1 could be a valid split pea line, as 3 + 4 + 7 = 14, which is 1 concatenated with 4. Digits may repeat on a line if allowed by the other rules. Lines do not cross, branch or share cells with other lines, but they may share circles.\nDots: Digits on a black dot are in a 1 to 2 ratio. Not all dots are given."

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.
Draw a one-cell wide snake, which starts in Box 5 and ends in Box 9, that moves orthogonally through the center of cells. The snake is not allowed to branch, intersect with itself or touch itself, even diagonally. Cells that are orthogonally adjacent along the snake have to contain consecutive digits. Within each box, the box number (1=top left, 2=top center, 3=top right, etc.) has to be part of the snake. Cells separated by a black dot contain digits that are in a 1:2 ratio. All black dots are given."

\n\nThe sum of the digits along a \u201edouble arrow\u201c is equal to the sum of the digits in circles attached to either end of the line. Each double arrow has its own color. Elements do the same color are connected.\n\nDigits in killer cages sum to the number in the top left corner (if given) and cannot repeat. Each killer cage has its own color. Elements of the same color are connected. \n\nAdditionally the grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues. (And a pair of missing shoes)!"

\n\u2022 Four yellow killer cages are hiding in the fog. Enter correct digits to clear the nearby fog. No guessing is necessary (or allowed!)\n\u2022 Digits in a killer cage sum to the small number in the top left corner of that cage. \n\u2022 Digits CAN repeat within a cage. In fact, a digit in a cage indicates exactly how many times that digit appears in that cage. Eg: a 5 in a cage means that there are five 5s in that cage.\n\u2022 Grey lines are bulbless thermometers. Digits along a grey line must be arranged in ascending order, from one end to the other.\n\u2022 White dots connect two consecutive digits. Not all possible white dots are shown."

\n\nThe following standard constraints apply: Dutch whisper, German whisper, Parity line, Ten line, Kropki, and XV. detailed rules below.\n\nStage Rules:\n\n1. Paths and Riders:\n Each line in the grid represents the path of a different rider:\n - Yellow Rider (Dutch Whisper)\n - Green Rider (German Whisper)\n - Red Rider (Parity Line)\n - Grey Rider (Ten Line)\n\n2. Scoring System:\n - Yellow Rider: Earns 1 point for every 5 on its path.\n - Green Rider: Earns 1 point for every 4 or 6 on its path.\n - Red Rider: Earns 1 point for every adjacent pair of consecutive digits along its path.\n - Grey Rider: Earns 1 point for every 3-cell segment that sums to 10 along its path.\n\nStage Results:\n1. Yellow Rider\n2. Green Rider\n3. Red Rider\n4. Grey Rider\n\nTo clarify, first place scored the highest amount of points, second place scored the highest after that and so on. There are no draws.\n\nDutch whisper: Two cells connected by a Yellow line must have a difference of at least 4.\nGerman whisper: Two cells connected by a Green line must have a difference of at least 5.\nParity line: Adjacent digits along the red line have a different odd/even parity.\nTen line: The Grey line must be divided into one or more contiguous groups of cells that each sum to 10. These groups of cells cannot overlap.\nKropki: Cells separated by a white dot must contain consecutive digits.\nXV: Cells separated by X must sum to 10. \nNot all dots and X's are necessarily given.\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.
\nAlong a thermometer, digits must increase from the bulb end. Digits cannot repeat in a cage and must sum to a number (in the circle) at the cage's top left corner.\nA digit that appears in a circle (killer value) indicates how many times that digit appears in all circles. A circle may contain a single-digit or double-digit number but cannot contain a multiple of 10. If it's a double-digit number, then each digit will be separately counted. For example, if a killer value of a cage is 35, then another two 3s and four 5s must be contained in the other killer values; this could be via either a single-digit 3 or 5, or double-digit totals that contain 3 or 5, like 13, 15, 25, 36, etc. No two killer cages of the same size can contain exactly the same combination of digits."

\n-The sum of digits along a line between two circles is equal to the sum of the digits in those two circles (ie Double arrows).\n-An X in the center of a 2x2 region of cells, a \u201cproduct square,\u201d indicates that the two digits in the square\u2019s positive diagonal have the same product as the two digits in its negative diagonal. The product is not necessarily the same for different product squares. Not all product squares are necessarily indicated. "

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.
Cells that are a knight's move away are not allowed to contain identical digits. Both digits (which can be equal) on the endpoints of a line form a look-and-say clue. For example, if the digits on the endpoints are 5 and 3, then there have to be exactly five 3s AND three 5s on this line. The different line colors are only used to avoid confusion regarding line crossings."

The snake can only move orthogonally from cell to cell, and may not touch itself, not even diagonally.\n\u2022 The snake functions as a zipper line; any pair of digits that are an equal distance from the central spot sum to the digit on that central spot.\n\u2022 Any pair of cells connected by a clue (dot, diamond, X or V) must either both be on the snake, or both be off the snake.\n\u2022 Cells connected by a white dot are consecutive.\n\u2022 Cells connected by black dot are in a 1:2 ratio (one is double the other.)\n\u2022 Cells connected by a green dot must have a difference of at least 5.\n\u2022 Cells connected by red diamond have the same parity (they're both odd or both even.)\n\u2022 Cells connected by an X sum to 10.\n\u2022 Cells connected by a V sum to 5."

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."

\n\nShade some cells so that the unshaded cells form a single orthogonally connected area, and each connected shaded region touches the grid boundary.\n\nA circle is always unshaded, and the digit in the circle equals the number of unshaded cells visible in a straight line from that cell, including the cell itself. Shaded cells obstruct the view.\n\nEach shaded region contains a corner clue which equals the sum of the digits in that region. Digits may not repeat in a shaded region, and the digit in the clued cell equals the size of the region."

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.
Adjacent digits along a green German whisper line must differ by at least 5. Both digits (which can be equal) on the endpoints of a green line form a look-and-say clue. If for example the digits on both endpoints of a line are 4 and 3, then the digit 3 has to appear exactly four times on this line AND the digit 4 has to appear exactly three times on the line. The line that starts in R2C6 ends at R2C8."

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.
All cells in the grid can be divided into two orthogonally connected regions with no 2x2 square entirely in either region. Each cage contains one cell that is not like the others, ie. one digit in each cage is in a different region than are all the others in that cage. The sum clue in a cage is the sum of the \u201cothers\u201d in that cage, eg. if the cage sum is 3 and there are three cells in the cage, there is an unknown digit that is in the opposite region from the other two, which are a 1 and a 2. Digits do not repeat within cages. A black dot joins digits that are in a 1:2 ratio. A white dot joins consecutive 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.
Box borders divide blue lines into segments with the same sum. Different blue lines can have different sums. If two digits (called x and y) are (orthogonally or diagonally) adjacent along a blue line, then x as well as y has to be an integer multiple of the difference between x and y. For example, 6 and 4 are allowed to be adjacent on a blue line since both 6 and 4 are a multiple of 2 (the difference between 4 and 6)."
