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.
The advantage of online games on Sudoku.com is that the game is always available and you can use various useful features. You can receive hints, correct or delete the entered data, take notes and stop the time needed to solve the puzzle. If you need to interrupt the game, you can always press a pause button.

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.
To play 24/7 Sudoku, employ the basic object of the game by clicking an open space and either typing the number that belongs, or selecting it from the numbers on the side of the sudoku board. If the number is correct, the sudoku tile will slide into its correct slot. If not, the number will return to the outside and time will be added to your overall sudoku game time. To highlight numbers, click a number that has aready been placed inside the sudoku puzzle. As the game progesses, you may want to use notes. Click the pencil in the right bottom corner to turn the numbers into notes. Just click it again to return to puzzle number form.
Easy Sudoku puzzles are perfect for beginners and kids to get acquainted with the rules and principles of the game. Seasoned players looking for a quick and straightforward challenge to clear their minds or just pass the time will also be able to enjoy this mode.
The difficulty levels in Sudoku depend on the number of filled cells allocated at the beginning of each game. The easy level is the variety that starts with the most allocated digits. Based on these, you must fill the remaining blank cells on the grid with numbers from 1 to 9, paying attention not to repeat the same digit in each column, row, or group. Finding the solution to an easy puzzle requires only attention, logic, and basic knowledge of the mechanics of the game.
The basic rule of Sudoku is that numbers can only appear once per row, column, and group. Since the easy level is the one where more hints are given right from the beginning, the best way to start is by focusing on the columns, rows, or groups with the most digits allocated and finding out which ones are missing.
For the next step, you can focus your attention on a specific group at a time. Find out the missing numbers in it and then check your possibilities block by block by testing the missing digit against the information of the row and column where it is inserted.
I believe in a number of books I have read and solved myself, the introduction stated that guessing should never be necessary for any of the puzzles in the book. Instead, a handful of techniques could be used to solve the puzzle completely, including the hard puzzles.
This one depends on what you accept as a "logical solution." In the strictest sense, the answer is again no. However, if you define a "logical solution" as excluding brute-force solving, the answer is probably "yes." There is some imprecise agreement on what constitutes a logical solution under this definition in the puzzling community, but based on this, we will again find that yes, there are definitely Sudoku puzzles that have no logical solution.
When I can solve a puzzle in ink, without erasures, with all deductions either positive or negative coming from visualization in my head and not making scratch-work on the paper, the puzzle is solvable by logic.
Again, the answer is "yes." In a competitive setting, most solvers would not use the more obscure techniques. After having narrowed possibilities somewhat with realistic techniques, some puzzles "require" guessing so as to not put the solver at a competitive disadvantage.
In these cases, the puzzles aren't more challenging necessarily (though they're typically written to be). While improper puzzles can be harder to solve, they are not usually more difficult to solve because they are improper, but rather because the design of the puzzle is more difficult.
My own experience, using the Sudoku app on my tablet, has been that every puzzle, no matter how difficult, can be solved by some technique, no matter how obscure. So, if you don't know a technique for a given situation, you may be reduced to guessing, but when asked for a hint, my tablet has always had a technique up it's sleeve for every possible situation.
If by 'guessing' you mean writing down numbers that you are not sure about, then no, every proper puzzle is solvable (in theory) by looking at all the possibilities remaining. This is the brute force algorithm.
However, some puzzles are complicated enough that you won't be able to remember all the possible values. This is simply a case of humans having poor short-term memory, and you will require additional resources (like writing down numbers and trying them).
As you get better and better at solving Sudoku puzzles, your brain recognizes more and more patterns, and when the puzzle you're solving matches one of those patterns, your brain can remember the solution. The more experience you have, the less difficult your reasoning becomes, and the less likely you are to find a puzzle that requires brute forcing.
I do a lot of sudokus. In at least 3 cases over the last few years, I found a puzzle that had more than one solution. It was an either/or type of thing. I had to choose which one of a pair of numbers was going to be the "solution" number. From there, I could solve the puzzle. I actually saved one puzzle and ran it both ways. It checked out each way. Very,very rare, but it happens.
I came across this result that claims that 16-clue sudokus are not solvable without guessing as they have multiple solutions possible. While they have used brute-force to go over all the solutions, there is no mathematical proof yet. I think.
