Sudoku del Día is the free daily sudoku that grows with you. One page, one date and four levels of difficulty — easy, medium, hard and expert — so you can pick the challenge that fits your morning: a gentle warm-up, a solid workout or a relentless duel with logic. The rules are the timeless ones: fill the 9×9 grid so every row, column and 3×3 box contains the digits 1 to 9 exactly once. Each level gets a different puzzle every day, so players worldwide solve the same grids. Given numbers are visually distinct, conflicts light up instantly, and the number pad works with mouse and touch. A timer tracks your session, and the puzzle remembers your progress during the day. Each difficulty is a genuinely different experience, making it ideal for beginners, daily players and veterans hunting minimal clues. What makes a daily sudoku special is the shared experience: on any given day, thousands of players are wrestling with exactly the same grid, and finishing faster becomes a quiet personal sport. The four-level format also lets your difficulty choice match your mood — gentle on Monday, merciless on Friday. Every puzzle is solvable by logic alone, preserving the purity that made sudoku a global phenomenon.
