Prime Sudoku
Prime Sudoku delivers a classic number puzzle experience optimized for Jio feature phones, blending relaxation with intellectual stimulation. The core objective is to complete a 9×9 grid by placing digits 1 through 9 so that each number appears only once in every row, column, and 3×3 subgrid. It's designed to sharpen logic and deduction skills through a clean, accessible interface.
To begin, select your preferred difficulty level from the available options. The game presents an incomplete grid. Your task is to fill all empty cells. Simply tap on a cell to select it, then choose a number from 1 to 9 to place within it. The puzzle is solved only when the entire grid is correctly filled according to the rules.
The gameplay revolves around pure logic. Each puzzle starts with several numbers already placed in the grid. You must use these given digits and the constraint of no repetitions in rows, columns, or boxes to deduce where each missing number belongs. The challenge scales with the difficulty setting, which determines how many numbers are provided at the start.
Start by scanning rows, columns, and boxes that are nearly complete, as they offer the clearest deductions. Work methodically, filling in cells where only one number can logically fit. If you get stuck, re-examine the intersecting rows and columns for the selected cell to uncover new possibilities.
