Play the online game Sudoku Calendar for free, originally titled Sudoku Calendar. Platform: Web browser (PC, mobile phones, and tablets) Technology: HTML5. Works in all modern browsers Fullscreen support Age rating: 3+ How to play? For those trying to fill out a Sudoku grid for the first time, we’ll explain: all cells in the grid must be filled with numbers, and no numbers can be repeated in a horizontal or vertical row. The entire board consists of 9 x 9 squares, each divided into cells with 3 cells in a row and 3 columns, respectively. Now you can start filling in the cells. But be extremely careful when checking for each number in a row or column, because if you make a mistake, you’ll lose one of your five attempts. If you find yourself in a difficult situation, it might be better to use a hint to continue the game and win. You’ll need a mouse to control the game.
