Inside a new Python script called sudoku.py, store all the values for the 9x9 grid.There is a snapshot button in the lower left corner to stop scanning so you can write down your answers.The code used in this project is available in this GitHub repo under the MIT license. HD mode - enables the highest resolution of the camera to improve the accuracy of OCR (Note: HD mode runs smoothly on the latest iPhones, older devices may lag, in this case please use SD resolution mode). Show possible numbers - possible filled-in numbers are shown in a blank grid like pencil marks (NOTE: only available when the solution mode is or ). Supports handwritten numbers - as long as they are written clearly.įocused view mode - scanned Sudoku board is enlarged to full screen size.Ĭlear view mode - the scanned Sudoku board is re-rendered with the numbers printed on a clear colored background. If the Sudoku board was solved correctly, a green bounding rectangle will be displayed, otherwise a red rectangle will be displayed, along with the grid with the error. Orange bounding rectangles indicate that the Sudoku board is unsolvable, and unsolvable grids are presented in flashing purple. Red bounding rectangles indicate that the Sudoku board is invalid (conflicting rows/columns/boxes), and invalid grids are presented with a red flash. A valid Sudoku board requires that the numbers in each row/column/box are unique.ĭifferent rectangles drawn on a recognized Sudoku board indicate the results of a checkĪ green bounded rectangle indicates that the Sudoku board is valid and can be solved. Hint a grid - tells you which grid is best to solve on the next move (i.e., fill in the grid with the fewest possible numbers).Ĭhecks if the puzzle board is valid, can be solved and has a single solution, the result of which is displayed superimposed on the camera image. Solve a grid - Solve a random grid for you. Solve all grids - Solve the puzzle completely. You can also pick a photo from the Photos album to solve.Ĭurrently supports 9x9 and 4x4 Sudoku boards. Also, error checks for invalid Sudoku boards are displayed on the camera image. This app identifies and solves Sudoku puzzles in real time and overlays the solution on the camera image.
