How to Play & Master

The goal of Sudoku is to fill a 9x9 grid with numbers so that each row, column, and 3x3 block contains all of the digits between 1 and 9. The Grid: The board consists of 9 rows, 9 columns, and 9 smaller 3x3 blocks separated by thick lines. The Rules: You can only use the numbers 1 through 9. A number can only appear once in each row. A number can only appear once in each column. A number can only appear once in each 3x3 block. Playing: Tap a blank cell to select it, then tap a number from 1 to 9 at the bottom of the screen to fill it in. Tools: Notes (Pencil Icon): Turn on Notes mode to write down possible numbers in a cell. This is crucial for hard puzzles. The "AI Note" button can do this for you automatically. Erase: Removes the number from the selected cell. Hint: If you select a blank cell and tap Hint, the game will reveal the correct number. Mistakes: Be careful! You usually have a limit on mistakes (e.g., 3 errors shown as hearts). If you lose all hearts, the game is over.
