- Solving a puzzle: Start filling in numbers between 1-9 in the unfilled cells, such that no row / column / block contains a duplicate. When you enter a duplicate number, the cell will be highlighted with light red background. Once you believe you have solved a puzzle, click on Verify button. If the puzzle has indeed been solved, the entire board will get highlighted with a light green background. Otherwise, the first erring cell will be highlighted with light red background.
- Auto solver: To solve a puzzle automatically, click on Solve button. Our AI based solver will try to solve the puzzle. If the puzzle is solved, you will see the result. If the AI fails to solve a puzzle because a unique solution is not possible, then you will be greeted with a new puzzle instead.
- Creating new puzzles: Although, with millions of possible auto-generated puzzles, you are likely to get a new unique puzzle each time. Yet, you may try to create a sudoku of your own to challenge your friends / yourself. Click on Create button to clear the board. Then, start entering the numbers in the cells which should be pre-filled in the final puzzle. Once you have entered the numbers, click on Done button. The resultant puzzle will be generated, and you will be able to share it with your friends using the social sharing buttons below.
