Sudoku Kingdom: Easy, medium and hard sudoku to solve with answers

Product Information

Easy level printable Sudoku puzzles are perfect for beginners. They contain more numbers on the playing field than medium or hard levels to help you get started. Medium Sudoku is a logic puzzle which is harder than an easy one and requires certain tactics to solve it. Sudoku is one of the most popular games to develop your intelligence. Supposedly, it was invented in 1970 by Dell's puzzler in New York, who published it in his journal “Mathematical Puzzles and Logical Problems”. The further development to web Sudoku was held in Japan, where the name of the game was invented. In 2004, Sudoku was first published in the “Times” as an online game. Sudoku is a brain challenging number game, played on a 9x9 sudoku board. The sudoku board is broken down into nine 3x3 squares. The object of the sudoku game is simple. Every row, column, and 3x3 box in the sudoku board must contain the digits 1 through 9 only once! As the difficulty progresses, the sudoku game becomes harder, and you'll have to employ more advanced and strategic logic to solve the puzzles. Make sure the sum of numbers in each cage is equal to the number in the upper left corner of the cage.

The level of difficulty depends on how many numbers are already shown in the cells: the more numbers, the easier the level. What You Get from Printable Sudoku Tip 2: Break the grid up visually into 3 columns and 3 rows. Each large column will have 3, 3×3 grids and each row will have 3, 3×3 grids. Now, look for columns or grids that have 2 of the same number. Logically, there must be a 3rd copy of the same number in the only remaining 9-cell section. Look at each of the remaining 9 positions and see if you can find the location of the missing number. Evil level printable Sudoku puzzles are made to push even the most seasoned Sudoku players to their limits.

The goal of Sudoku is to fill the cells with numbers from 1 to 9. The numbers are placed in 9 squares, 3x3 each, thus, in each row, in each column and in each small square there are 9 cells. The same digit can be used only once in each separate column, each line and in each small square. The level of difficulty depends on how many digits are already indicated in the cells. If you open plenty of numbers - then you have very easy Sudoku.
