Sudoku Pop — Classic Number Logic, Five Ways

Sudoku Pop is a free browser version of the classic 9x9 number puzzle: fill every row, column and 3x3 box with the digits 1 to 9, using nothing but logic. Built in plain HTML, CSS and JavaScript, it loads instantly and needs nothing installed.

How It Works

Pick a difficulty and a fresh puzzle is generated with a single guaranteed solution. Tap a cell and choose a number, or switch on notes to pencil in the candidates you are still weighing up. Correct placements in a row build a streak bonus, while mistakes cost points — and three of them end the run. Free hints are there when a grid stalls, but the harder the difficulty, the fewer you get.

Frequently Asked Questions

Is Sudoku Pop free to play?
Yes. Sudoku Pop is completely free, runs in your browser, and needs no download, install or sign-up.
How many difficulty levels are there?
Five — Easy, Medium, Hard, Expert and Master. Harder levels start with fewer given numbers and give you fewer free hints, from five on Easy down to one on Master.
Does every puzzle have a solution?
Yes. Each grid is generated and then checked to make sure it has exactly one valid solution, so every puzzle can be solved by logic alone with no guessing.
What happens if I make a mistake?
A wrong number costs you points and counts against you. Three mistakes end the run, so you can restart the grid or start a fresh puzzle.
Does Sudoku Pop save my progress?
Your current grid, best times, best scores, win rate and daily streak are stored locally in your browser. No account is needed and nothing is uploaded.
