Gameplay and Features

• [Core Gameplay Loop]: Players fill a 9×9 grid so each row, column, and 3×3 subgrid contains all numbers 1-9 exactly once, starting from partially filled grids. Objective is to complete the grid correctly, interacting with cells by selecting, erasing, and inputting numbers.
• [Visuals or Art Style]: The game features clean, minimalist grid graphics with subtle color coding for rows, columns, and boxes. Numbers are typically large, bold, and clearly defined with a simple, elegant interface.
• [Modes or Levels]: Multiple difficulty levels (Easy, Medium, Hard) offer varying numbers of starting clues. Features include Timer, Note Mode, Check Progress, Undo, Hint, and Pencil Marks to aid different solving styles.

How to Play

Beginner’s Guide:

• Step 1: Launch the Sudoku app or website, select Beginner difficulty (or Easy mode), and view the partially filled 9×9 grid.
• Step 2: Use the number pad to input your chosen numbers into empty cells, ensuring each row, column, and 3×3 box will contain all numbers 1-9 exactly once.
• Step 3: Tap the “Check” button to verify your solution. When the grid is complete with no errors, tap “Submit” to finish the puzzle or continue solving for completion.

Pro Tips:

• Start from the corners and edges where numbers with fewer possibilities often provide clues to solve other sections.
• Use the Pencil Mark mode to tentatively note potential numbers for empty cells, helping visualize possibilities without committing to them.
• Look for “Singles” or “Naked” numbers (cells with only one possible number remaining) and “Hidden Singles” (numbers appearing only once in a row/box/column) as reliable starting points.
