Just click the icon again to switch to placing big 'final' decisions (you can erase any of these too in case you change your mind). ![]() Just click the 'note' icon - now every number you put in a cell will be a small note alongside other candidates. Just like in a paper Sudoku, you can make 'small pencil notes' in the cell of which numbers can go there. No matter what trick you use the most helpful thing for solving a Sudoku is 'penciling the candidates'. Now draw a horizontal and vertical line from every 4 on the board (you remember you can't place another 4 in a row or column) - it will quickly become clear there are almost no cells left where you can actually put it. Choose a number that occurs most on the board already (so there's one or two instances left to place) - there are indicators below the board to help you find the best one. The more advanced technique you can use for a harder puzzle called 'scanning': it exploits the fact that any given number from 1 to 9 can occur only nine times in a completed Sudoku puzzle. Now you will notice the more and more rows, columns and regions become almost complete and easy to deduce - the complete puzzle picture becomes clearer with each move. Now try to use the same technique but now with an almost filled-in row or column - find the one where only one number missing (then the answer is obvious) or two ones missing - try both options and figure out the right one. Which one is correct? Just place 3 and look across the whole row, then the column: is there a duplicate? Try the same with 7 and you'll get the correct option. For example, if a 3x3 square lacks just the numbers 3 and 7, we have only two options on how to place these two remaining numbers - 3 in a first cell and 7 in a second one or vice versa. You will certainly see a square where just one or two numbers are missing. Start a Sudoku puzzle on an Easy level to learn all the techniques quickly. Sounds like a tricky task? Just start scanning the board and you'll find all clues you need, one by one, and get the puzzle solved. So each number from 1 to 9 occurs only one time in each row, column and region. Now you just need to fill the remaining cells with numbers from 1 to 9, obeying the only rule:Įach row, column or region must not contain repetitive numbers. The more cells are pre-filled the easier the puzzle. You start a Sudoku puzzle with some cells already filled in with numbers. So each row, column or region contains nine cells. In each Sudoku puzzle you have a 9x9 grid, divided into nine 3x3 square regions (you can just look above to get an impression). ![]() DONATE FEEDBACK More Games Puzzles Solitaire Mahjong How to Play Sudoku
