These puzzles do not require more than one hypothesis by multiple choice.īy hypothesis we mean a supposition about the solution of a square in the absence of any logical reasoning. We already know they cannot contain 3 because adjacent cells share. For instance, if one cell contains a 3 then the adjacent cells must not contain 2 or 4. That rule is that, quite simply, the values placed in cells must be non-consecutive. Puzzles 'Expert' are soluble with ' Inclusion', ' Exclusion, and ' Multiple Choice'. Non consecutive sudoku is an interesting change to the standard puzzle, and introduces one key new rule.Puzzles 'Confirmed' are fully soluble by ' Inclusion' and ' Exclusion' while admitting other methods.Puzzles ' Beginner' are fully soluble by ' Inclusion'.

We recommend you try Google Chrome, for its speed and its various features are very welcome when it comes to solving puzzles of 256 squares. The hexadecimal is especially useful in computer science because it is much easier to map binary to hexadecimal than to decimal. The hexadecimal system is a numeral system with a base of 16, using Arabic numerals to represent values 0-9 and the letters A-F for the other six. To reduce the size of the grid on the screen and to facilitate entering values, the possibilities are represented here by the following hexadecimal digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F. That means each row, column, and 3×3 square in a Sudoku puzzle must contain ONLY one 1, one 2, one 3, one 4, one 5, one 6, one 7, one 8. No row, column, or 3×3 box can feature the same number twice. The solving techniques are identical to those of a classic sudoku. In Sudoku, you must complete the grid so each row, column, and 3-by-3 box (in bold borders) contains every digit 1 through 9.

The hexadoku is 16 X 16 squares instead of 9 X 9 squares.
