Objective

Tips
Scoring
Sudoku — Easy is a time-based ladder on a gently-clued puzzle. Solve fast; the faster you finish, the higher you score.
How the score is calculated
The clock starts the moment you place your first digit. When the grid is fully and correctly filled, the timer stops and your score is locked in:
score = max(100, 3000 − seconds × 5)
