His puzzles immediately met with unbelievable success and are now played the world over by children, adults and the elderly.

the Mathematics of Sudoku
A completed Sudoku grid is a special type of Latin square with the additional property of no repeated values in any of the 9 blocks of contiguous 3×3 cells. The relationship between the two theories is now completely known, after it was proven that a first-order formula that does not mention blocks (also called boxes or regions) is valid for Sudoku if and only if it is valid for Latin Squares (this property is trivially true for the axioms and it can be extended to any formula).
Calcudoku mixes in arithmetic to the familiar Sudoku-type puzzle game. However, you might find that Calcudoku is often more challenging than the generic Sudoku game. You'll notice that there are various angles that you must exploit to arrive at a unique solution.
I have personally played Calcudoku many times on the online website before I decided to make this app. It's a great game to practice your logic skills and/or relieve your boredom.
- Special input controls: You can either drag a cell or use the number pad to add a number.
- Many puzzles: I will keep adding puzzles as long as people keep wanting them. Currently there are 80 puzzles for every size. That's 480 in total.
- Colorful user interface
- Categorized by size: You can choose to play out of any board size between 4x4 and 9x9.
- Undo button

Sudoku is the most popular logic-based game. The aim of the game is to completely fill the entire grid with numbers, such that every 3x3 box, every row and every column contains each of the numbers 1 to 9.
Every Sudoku puzzle has to have only one (unique) solution that can be reached logically without guessing. It's the most important rule of Sudoku. So by definition, a Sudoku puzzle which doesn't have a unique solution is unsolvable. Unfortunately, most Sudoku games on the Internet produce puzzles that have non-unique solutions.
TRUE SUDOKU contains only VALID puzzles with UNIQUE solutions!
Classic Sudoku puzzle initially contains given clues in various places. The difficulty of a puzzle is determined by the count of starting givens and depth of logic required. Most Sudoku games in addition to standard difficulty levels (easy, medium, hard) have the level of increased complexity called extreme level. But basically extreme puzzles are not as difficult as it seems. The smallest number of starting clues a valid puzzle can contain is 17. Ideally, extreme level should produce the most complex puzzles with 17 givens.
TRUE SUDOKU has EXTREME level that produces puzzles with 17 givens.
All you need for playing Sudoku puzzle is some logical thinking and a little patience. True Sudoku is perfect touchscreen game with easy navigation and fun to play!

Japanese crosswords, also known as nonogram, hanjie, griddlers, picross, crucipixel, edel, figurepic, grafilogika, japanilaiset, karala!, kare, logicolor, logigraphe, oekaki, oekaki-mate, pic-a-pix, pikurosu, ristikot, shchor, square, tsunami, uftor or paint by numbers puzzles, started appearing in Japanese puzzle magazines. Non Ishida published three picture grid puzzles in 1988 in Japan under the name of "Window Art Puzzles". Subsequently in 1990, James Dalgety in the UK invented the name Nonograms after Non Ishida, and The Sunday Telegraph started publishing them on a weekly basis.
In japanese nonograms the numbers are a form of discrete tomography that measures 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. To solve Japanese nonogram, one needs to determine which squares will be filled and which will be empty.
These nonograms are often black and white, describing a binary image, but they can also be colored. If colored, the number clues are also colored to indicate the color of the squares. In such crossword two differently colored numbers may have a space in between them. For example, a black four followed by a red two could mean four black boxes, some empty spaces, and two red boxes, or it could simply mean four black boxes followed immediately by two red ones.
Hanjie has no theoretical limit on size, and is not restricted to square layouts.
Griddlers were implemented by 1995 on hand held electronic toys in Japan. They were released with name Picross - Picture Crossword.
The aim of the game is to place 1 to 9 into each grid cell so that each number can only appear once in each row, each column and each mini-grid.
