Import a puzzle
Bring a Sudoku in from anywhere. Choose how it gets here, and we'll do the rest — verify it has a unique solution, rate its difficulty, and let you solve it with step-by-step hints.
Paste a string
Already have an 81-character Sudoku string — from another puzzle's Share menu, a forum, or another app? Paste it in and play instantly.
Paste a stringScan an image
Have a photo instead — a newspaper, a puzzle book, or a screenshot? We'll find the grid, read every digit and pencil mark, and let you confirm before you play.
Scan an imageNot sure which one? If you can copy the puzzle as text, pasting is faster and always exact. If all you have is a picture — including one of a puzzle you've already started solving, pencil marks and all — scanning reads it directly from the image.
