Sudoku
Fill the grid so every row, column, and box holds one to nine — new board daily.
How to play Sudoku
Every day brings one fresh puzzle — the same board for everyone that day. Fill the empty cells so that every row, every column, and every 3×3 box contains the digits 1 to 9 exactly once.
Tap a cell to select it, then tap a number on the pad to place it. Tapping the same number again clears it. The bold given digits are locked and can't be changed.
If a digit repeats in a row, column, or box, the clashing cells are ringed in red with a corner marker so you can spot the mistake and fix it.
Fill the whole grid with no clashes to solve it. A timer tracks how long you take, and solving day after day builds a streak.

Tips
- Scan for a row, column, or box that's nearly full — the last few digits there are often forced.
- Selecting a cell highlights its row, column, and box, plus every matching digit, so you can see at a glance where a number can still go.
- Pencil the obvious cells first; the puzzle always has exactly one solution, so you never need to guess.
- It's a daily — solve it today to keep your streak alive, and a faster solve earns a higher score.
About Sudoku
Sudoku is Navritto's daily number-logic puzzle, built to play instantly in the browser. Each calendar day a single medium puzzle is generated from that day's seed, so everyone plays the identical, uniquely solvable board — and it's the same puzzle whether you reload the page or come back later. Select a cell and enter a digit with the on-screen pad or the keyboard; the grid flags any row, column, or box clash, a timer tracks your solve, and completing the board each day extends a streak saved on your device. It needs no install or account and works with touch or the keyboard. Sudoku joins Coil, Doubler, Pairs, Skyhop and Skyline in Navritto Games and shares the same feel — the pop, the glow, the little celebration on a solve — that runs through them all.
