Sudoku evil has 4 much tougher-to-solve puzzle levels compared to regular Sudoku puzzles when it comes to difficulty. This highly complex kind of 9×9 Sudoku puzzle is played by completing each of its 4 difficult levels. All levels of the puzzle are considered to be highly difficult to complete, with an increasing difficulty after each level. Some people who try to solve this kind of Sudoku puzzle leave the game without completing a single level due to its very hard-to-solve nature.
In an evil Sudoku puzzle, there are, at most, 4 prearranged numbers in each sub-square. Because it has fewer givens, most players find it hard to start completing even a single evil Sudoku sub-square. It is even usual that you see sub-squares that only have 1 or 2 prearranged numbers in an evil Sudoku sheet.
However, evil Sudoku’s complexity and difficulty is what makes it wanted by those Sudoku enthusiasts who love more challenging puzzles. This extraordinary puzzle is often played by Sudoku masters who use their logical skills in an unordinary manner. Successfully completing all four levels of evil Sudoku really makes you extraordinary.
The question here is: What do you need to do in order to successfully complete all four levels of evil Sudoku?
START WITH SUB-SQUARES
As mentioned above, each sub-square may only contain four prearranged numbers at most. Since this is the case, it would be best if you start filling those boxes inside sub-squares with the most number of givens and answer last those sub-squares with only 1 or two givens. You should notice here that it is just like in a regular 9×9 Sudoku puzzle where answering the sub-square with the most number of givens should be top priority.
GIVE EXTRA EFFORT
I hope by now you understand that evil Sudoku has a much more difficult nature compared to regular Sudoku puzzles. Because of this, you should give extra effort in solving this kind of puzzle. You need to exert double effort if you really want to complete all its 4 levels. You need to be very thorough and meticulous when checking every corner of the puzzle for duplicates and make sure to use your best analytical and logical skills.
PENCIL, PENCIL, PENCIL
Since evil Sudoku has very few givens, it is to your advantage if you try to write numbers inside certain boxes that might be the right fit on those boxes. And you can only effectively do this by using a pencil – make sure you also have an eraser. The importance of using a pencil – and not a pen or any permanent marker – in solving any Sudoku puzzle can be seen here because this involves much number-elimination.
YOU WILL NEED MORE THAN PATIENCE
In completing the 4 levels of Sudoku Evil, having patience is not enough. You must have the determination to complete it. Keep in mind that you are not just dealing with a regular, ordinary Sudoku puzzle; you are trying to complete one of the hardest-to-solve number puzzles that you can find. If you think you have what it takes and are tough enough to beat and finish this particular puzzle, then you are ready to roll.
