About Prime Sudoku
Sudoku is a relaxing yet challenging number puzzle game made for Jio feature phones. Fill the 9×9 grid with numbers 1 to 9 without repeating any in a row, column, or 3×3 box. Choose from different difficulty levels and test your logic skills.
It leans fully into puzzle, so if that's your thing, it delivers. Pick it up for a short break or settle in for a while — it runs well on phone, tablet, and desktop alike.
If you want to do well, keep this in mind: Slow down on the first level — the early stages teach mechanics you will need at the end. Take a screenshot of a tricky board before experimenting, so you can always reset in your head.
You can play Prime Sudoku free online at Glaze Games — it loads in seconds, works on phone and desktop, and never asks you to sign up.
