Tridoku This is a brand new and very interesting puzzle. It has many similarities with Sudoku, however in a completely different layout, so it takes some getting used to. Here are the rules: 1. There are 9 nonets in forms of triangles. These are drawn with thick lines. All must contain all numbers 1-9. 2. Each edge of the big triangle contains 9 numbers again, no repeats there either. These cells are shaded in LIGHT GRAY. 3. There is an INNER triangle, shaded in DARK GRAY. Each side of the inner triangle contains 9 numbers. No repeats on those sides, please. 4. And finally, the most important rule: two cells that are touching each other must not contain the same number. Each cell is touching up to 12 other cells! Be careful! 2/22
Slitherlink (also known as Fences, Takegaki, Loop the Loop, Loopy, Ouroboros, Suriza and Dotty Dilemma) Slitherlink is played on a rectangular lattice of dots. Some of the squares formed by the dots have numbers inside them. The objective is to connect horizontally and vertically adjacent dots so that the lines form a single loop with no loose ends. In addition, the number inside a square represents how many of its four sides are segments in the loop. 3/22
Hidoku (also known as Hidato) The goal of Hidato is to fill the grid with consecutive numbers that connect horizontally, vertically, or diagonally. In every Hidato puzzle the smallest and the highest number are listed on the grid. There are more numbers on the board to help to direct the player how to start the solution and to ensure that Hidato has only a single solution. It is usually played on a square grid but can also include irregular shaped grids like hearts, skulls, and so forth. 4/22
Outside Sudoku The inner 9x9 square is a classic Sudoku puzzle; however, there are no clues inside it. Instead, the clues are positioned outside of the inner puzzle. The clues tell you which number or numbers must appear in the 3 cells closest to it (in the corresponding row or column). The clues are not necessarily given in the same order as they appear in the solution. The beauty of Outside Sudoku is that it can be combined with any Sudoku variant (such as Jigsaw, Consecutive etc.). Also, in this variant you must solve all 81 cells, which means you have more solving per puzzle to do! 5/22
Non-consecutive Sudoku If you think this is a classic Sudoku puzzle, you are wrong! Why? Because there is an additional rule: two consecutive numbers must not touch each other horizontally or vertically! This rule has to be clearly indicated when this type of Sudoku is published, because the puzzle looks exactly like normal Sudoku, but it is not. 6/22
Sudoku Straights (also known as str8ts) The goal of the Straights is similar to Sudoku, but not exactly the same: fill in the white cells with numbers from 1 to 9, without repeating any number in rows or columns. There are no 3x3 boxes (nonets) like in classic Sudoku! Also, since there are some black cells, not all of the numbers from 1 to 9 will appear in every row and column. Black cells do not contain numbers! And finally, the main rule: each set of numbers between two black cells (or between a black cell and the border) must constitute a straight, which is a term borrowed from poker. For example: 73645 is a straight; 5689 is not a straight! 7/22
Calcudoku (also known as KenKen, KenDoku, MathDoku) The goal of each puzzle is to fill a grid with digits 1 through 4 for a 4 4 grid, 1 through 5 for a 5 5, etc. so that no digit appears more than once in any row or column. Grids range in size from 3 3 to 9 9. Additionally, Calcudoku grids are divided into heavily outlined groups of cells often called cages and the numbers in the cells of each cage must produce a certain target number when combined using a specified mathematical operation (addition, subtraction, multiplication or division). For example, a three-cell cage specifying addition and a target number of 6 in a 4 4 puzzle might be satisfied with the digits 1, 2, and 3. Digits may be repeated within a cage, as long as they are not in the same row or column. No operation is relevant for a single-cell cage: placing the "target" in the cell is the only possibility. The target number and operation appear in the corner of the cage. 8/22
Greater/Less Than Sudoku A classic Sudoku puzzle but without any clues. Instead, there are inequality signs, greater than > and less than < between cells. Obviously, they tell you which number in the two cells is greater. This kind of puzzles is difficult to crack in the beginning, but later they flow fairly easily. First you have to find a cell that has, for example, many > signs around it. If it has 4 such signs, it means the number in it can be at least 5 (because it is greater than at least 4 other numbers). When you combine these clues, you narrow done the possibilities and eventually solve one cell. 9/22
Kakuro (also known as CrossSums) The object of the puzzle is to insert a digit from 1 to 9 inclusive into each white cell such that the sum of the numbers in each entry matches the clue associated with it and that no digit is duplicated in any entry. Puzzles are usually 16 16 in size, although these dimensions can vary widely and can be of any size and shape. 10/22
Nurikabe The puzzle is played on a typically rectangular grid of cells, some of which contain numbers. The challenge is to construct a block maze (with no particular entrance or exit) subject to the following rules: The "walls" are made of connected adjacent "blocks" in the grid of cells. At the start of the puzzle, each numbered cell defines (and is one block in) a wall, and the number indicates how many blocks the wall must contain. The solver is not allowed to add any further walls beyond these. Walls may not connect to each other, even if they have the same number. Any cell which is not a block in a wall is part of "the maze." The maze must be a single orthogonally contiguous whole: you must be able to reach any part of the maze from any other part by a series of adjacent moves through the maze. The maze is not allowed to have any "rooms" -- meaning that the maze may not contain any 2x2 squares of non-block space. (On the other hand, the walls may contain 2x2 squares of blocks.) 11/22
Hyper Sudoku (also known as Windoku) All standard Sudoku rules apply. In addition, the 4 shaded 3x3 boxes must also contain all numbers from 1 to 9 each. 12/22
Butterfly Sudoku X (diagonal) This is just one example of an overlapping Sudoku variant (Gattai-4), combined with another Sudoku variant Diagonal Sudoku. So, there are 4 standard Diagonal Sudoku puzzles which heavily overlap each other. Look at the thin diagonal grey lines to figure out how the puzzles overlap. Then, solve each one of them as you normally solve Diagonal Sudokus. You must use the infamous Twin Nonets solving method for such puzzles! 13/22
Zero Killer Sudoku Killer Sudoku combines elements of Sudoku with Kakuro usually, no initial numbers are given, but the 9 9 grid is divided into regions (known as cages), each with a number that the sum of all numbers in the region must add up to and with no repeated numerals. These must be filled in while obeying the standard rules of Sudoku. This particular puzzle is a variant of Killer Sudoku. In normal Killer Sudokus, each cell belongs to one cage. However, in this kind, some cells are left out of any cages, so there are even fewer clues which makes this variant one of the hardest puzzle types. 14/22
Hitori Hitori is played with a grid of squares or cells, and each cell contains a number. The objective is to eliminate numbers by filling in the squares such that remaining cells do not contain numbers that appear more than once in either a given row or column. Filled-in cells cannot be horizontally or vertically adjacent, although they can be diagonally adjacent. The remaining un-filled cells must form a single component connected horizontally and vertically. 15/22
Jigsaw Sudoku (aka Squiggly Sudoku, Irregular Sudoku) The 3x3 boxes have been redesigned and now they are irregularly shaped. Just like in classic Sudoku, each row or column must contain all numbers from 1 to 9. Also, each nonet (9 cells grouped together in an irregular shape, just like in jigsaw puzzles) must contain all numbers from 1 to 9. Basically, the only difference between classic Sudoku and Jigsaw Sudoku is the shape of the nonets. 16/22
Sudoku X (diagonal Sudoku) One of the first variants of Sudoku, where there is one more restriction: both diagonals must contain all numbers 1-9 each. The diagonals are marked by thin grey lines. 17/22
Odd/Even Sudoku White cells must contain even numbers. Shaded cells must contain odd numbers. Otherwise, standard Sudoku rules apply. 18/22
Consecutive Sudoku Remember the non-consecutive sudoku from a few pages above? Well, this is similar. All standard Sudoku rules apply. Two cells with a pipe symbol between them MUST contain consecutive numbers (5 and 6, for example). Two cells without the pipe symbol CANNOT contain consecutive numbers, they must be non-consecutive (just like in non-consecutive sudoku). 19/22
TwoDoku One of the most popular Overlapping Sudoku: two classic Sudoku puzzles that overlap each other. Twin Nonets rule can be applied, but be careful. 20/22
Hanjie Nonograms, also known as Paint by Numbers or Griddlers are picture logic puzzles in which cells in a grid have to be colored or left blank according to numbers given at the side of the grid to reveal a hidden picture. In this puzzle type, the numbers measure how many unbroken lines of filled-in squares there are in any given row or column. For example, a clue of "4 8 3" would mean there are sets of four, eight, and three filled squares, in that order, with at least one blank square between successive groups. 21/22
Samurai Sudoku This is probably the most popular sudoku variant. My Samurai Sudoku puzzles appear in The Washington Post every Sunday since 2005. It s a Gattai-5 Sudoku puzzle, meaning that 5 classic Sudoku grids overlap each other to form one puzzle. Each of the 5 sub-puzzles cannot be solved on its own. One must use the clues from the overlapping regions. The whole puzzle has one solution only. 22/22
