Sudoku Screenshot Coach

Drop in a screenshot with a sudoku somewhere in it. The tool finds the grid, reads the digits, and tells you the next move to make, and why that move is forced.

1. Load a puzzle

Drop a screenshot, paste it, or choose a file

The sudoku can sit anywhere in the picture, next to anything else. Press Ctrl+V (Cmd+V on a Mac) to paste one straight from the clipboard.

2. Check the grid

Select a cell and type a digit to fix anything the reader got wrong. Press Backspace to empty a cell. Cells the reader was unsure about are marked.

3. Get the move

The techniques it knows

The coach always offers the easiest technique that works on your grid, the way a teacher would. These are the ones it can find and explain, from the simplest to the hardest.
