Sudoku Game: 5 Levels Of Difficulty

Between a compact 4x4 grid and a full 9x9 layout, Sudoku Game: 5 Levels Of Difficulty covers quick number sets and longer pencil-mark sessions. Five modes set the pressure: beginner, easy, medium, hard, and expert. Both board sizes are available across those settings. The smaller grid uses 16 cells. The larger one fills 81 spaces. The 4x4 version follows the same Sudoku rules, with a shorter format that reads faster on every setting. The 9x9 board suits regular Sudoku players and longer number searches.

How to play?

Place digits so no row repeats a number. Follow the same rule down each column. Every 3x3 block on the 9x9 board must also contain non-repeating digits. Uncertain cells support notes. Mark several possible numbers in one space, then return when later placements narrow the choice. Fill the squares with confirmed values first. Use the hint button in the upper-right corner if the grid stalls. A completed puzzle triggers the Sudoku window.
