Sudoku – Numra Puzzle Game

Sudoku the way it should be: a clean, classic number puzzle you can open offline any time. No energy bars, no account, no clutter between you and the grid.

Numra adapts to where you are. Start on Easy to learn how rows, columns and boxes lock together, then work up to Expert grids that demand real deduction. Every puzzle is generated with exactly one solution, so you never hit a board that cannot be solved by logic alone.

Built For Real Solving
Pencil marks let you jot candidate numbers into a cell exactly like you would on paper. Smart highlighting shows every cell sharing a row, column or box with your selection, and flags conflicts the moment they appear — so you catch your own slips instead of discovering them twenty moves later.

A New Puzzle Every Day
The Daily Challenge hands everyone the same grid each day and counts how many days in a row you have solved it. Miss a day and the streak resets, which turns out to be a surprisingly good reason to come back tomorrow.

Plays Anywhere
No internet required. On the bus, in a waiting room, on a plane with no signal — the full game works offline, including the daily puzzle. Nothing loads, nothing buffers, nothing interrupts.

New To Sudoku?
It is a logic puzzle, not a maths test — you never add or multiply anything. Fill every row, every column and every 3x3 box with the digits 1 to 9, using nothing but elimination. The rules take thirty seconds to learn, and the hardest grids can still hold you for an hour. That gap is why Sudoku has stayed one of the most played number puzzles in the world.

Numra keeps that experience calm and uncluttered. Just you, the grid, and the next number.
