How to play
What Sudoku does with numbers, Unolingo does with the alphabet. Most puzzles take 5–15 minutes.
1
Pick your level
Choose from four difficulty levels, from 1-star (easiest) to 4-star (most challenging). Harder puzzles give fewer letter clues.
2
Place every letter
Drag each of the 26 letters to the square where it belongs. Every letter is used once and only once.
3
Get unstuck
Use a Hint to reveal one square, or an Audit to see which of your letters are right, each for a small time penalty.
