Most people know sudoku as the traditional 9×9 sudoku, which is found at the bottom of the last pages of the newspapers and can be filled with pen or pencil in 5 minutes. This is the most common and most commonly used version. But there are also a few goodies, which differ in size, form and filling rules from the tradition.
There are 2×2, 4×4, 6×6, 8×8 and bigger ones: 12×12, 16×16, 20×20 and 25×25. They differ only in their size from the basic version, their filling rule is the same.
And there are some that are slightly different:
– the X-sudoku, where the translucent specificity is also to be considered
– samurai sudoku, the combination of several square sudoku,
– the renban, also called amoeba sudoku, where an irregularly shaped playing area is to be found,
– sudoku gusu, where only gray numbers can be written in gray cells,
– the killer sudoku, where the number of numbers in the indicated cells has already been given,
. and there is the larger sudoku, where adjacent fields belonging to a block are given which element is smaller or smaller or bigger.
Sudoku Crosswords are two dimensional puzzles. If we imagine such a puzzle in space, we get a sudoku cube. There is also a couple of variations of this, other than the rules of unloading.
For example, su3Doku, a sudoku cube. An imaginative and accomplished 3D sudoku game with a unique set of rules. The game area is a 3x3x3 cube side, reading 3-3 pages vertically and horizontally. The rule is the same as in the original version: a number from 1 to 9 can only appear once on the big cube pages. What is different is that the puppies are within the frame, they must be put to the right place.
This game is not a five-minute task, but you can also use a pen or pencil here.
