It features a 6圆 grid, which is divided into smaller 2x3 regions. Of course 'Undo' and 'Redo' can be helpful too - the icons are just right of the board.Īnd be sure to open the Settings page (using the gear icon) and try various error highlighting modes - that's the indispensable tool for getting the hand in quickly finding the right candidates.Sudoku 6圆 is a variant of the classic Sudoku puzzle, tailored to be more accessible and often used as an introductory version of the puzzle. 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.
