About Sudokrine
Sudokrine is a free daily medical sudoku with a hidden word. Each grid uses the letters of a medical word with no repeated letters, often a hormone or gland. Fill every row, column and box with each letter once, and the shaded line spells the word. Early in the week it's a 6x6 mini; Friday to Sunday it's a full 9x9.
How to play
- Tap a square, then tap a letter. Notes mode adds pencil marks.
- Every row, column and box gets each letter exactly once.
- Guess the hidden word under the grid before you finish for a Word bonus.
- Prefer digits? Tick Show numbers.
