About this game

New Daily Sudoku gives you a fresh, hand-crafted sudoku puzzle every single day across four difficulty levels — easy, medium, hard, and expert. You fill in the 9 by 9 grid so that every row, column, and 3 by 3 box contains each digit from one to nine exactly once. The puzzles are designed to have unique solutions and clean logical paths, so a tough one is always solvable without guessing. A clean interface lets you mark candidate numbers, highlight conflicts, and undo mistakes without breaking flow. The daily format is the real draw — coming back tomorrow for a new challenge builds a quiet habit that's surprisingly rewarding. This HTML5 game plays in your browser with no download.
