Core Game Mechanics & System Architecture

While traditional Sudoku uses a $9 \times 9$ grid divided into $3 \times 3$ regions, Daily Mini Sudoku focuses on streamlined $4 \times 4$ and $6 \times 6$ grid variations. This structural shift retains all core deductive depth while drastically reducing board clutter and solving time.

1. The $4 \times 4$ Mini Grid (Beginner & Speed Modes)

• Digits Used: Numbers $1, 2, 3,$ and $4$.
• Sub-Grids: Four distinct $2 \times 2$ internal boxes.
• Solving Speed: Typically solved in 30 seconds to 2 minutes. Perfect for young learners, beginners, or high-speed warmups.

2. The $6 \times 6$ Midi Grid (Standard Daily Challenge)

• Digits Used: Numbers $1, 2, 3, 4, 5,$ and $6$.
• Sub-Grids: Six distinct $2 \times 3$ internal regions.
• Solving Speed: Typically solved in 2 to 5 minutes. Delivers the ideal balance of spatial deduction, variable elimination, and quick tactical satisfaction.

3. Pure Logic & Single Unique Solutions

Every puzzle in Daily Mini Sudoku is strictly handcrafted or algorithmically verified to guarantee a single, unique logical solution. Players never need to guess or gamble—every single empty cell can be solved through pure, systematic deduction!

Comprehensive "How to Play" Instructions

The core rule of Sudoku is universal, elegant, and instantly easy to learn: Fill every cell so that no number repeats in any row, column, or sub-grid box.

Step 1: Understanding the Rules

For a standard $6 \times 6$ Mini Sudoku board:

1. Rows: Every horizontal row of 6 cells must contain all digits from $1$ to $6$ without repeating any number.
2. Columns: Every vertical column of 6 cells must contain all digits from $1$ to $6$ without repeating any number.
3. Boxes (Regions): Every $2 \times 3$ rectangular sub-grid must contain all digits from $1$ to $6$ without repeating any number.

(Note: On a $4 \times 4$ Mini Sudoku board, simply use digits $1$ through $4$ across 4 rows, 4 columns, and four $2 \times 2$ boxes).

Step 2: Selecting a Cell and Entering Digits

1. Tap a Cell: Touch or click any empty cell on the board to highlight it. The game will automatically highlight the corresponding row, column, and $2 \times 3$ box to help you visualize active constraints.
2. Input a Number: Tap the desired number from the number pad below the grid to insert it into the active cell.
3. Using Pencil Notes: Toggle the Pencil Mode button (or hold down a number) to input small candidate numbers into a cell. Use pencil marks when multiple numbers are possible and you want to track your remaining options!

Step 3: Eliminating Impossibilities

To solve an empty cell, scan its row, column, and surrounding $2 \times 3$ box:

• If numbers $1, 2, 3, 5,$ and $6$ are already present across that cell's row, column, and box, then by pure process of elimination, the remaining empty cell must be $4$!

Step 4: Correcting Mistakes & Completing the Grid

• Conflict Checking: If you accidentally place a duplicate number in a row, column, or box, the game highlights the conflicting numbers in a warm, subtle red.
• Winning the Puzzle: Continue filling empty cells until every single square on the board contains a valid number. Once the last correct digit is placed, the board glows, logging your completion time and updating your daily streak!

Pro Strategies & Solving Tactics

1. Focus on Nearly Complete Lines: Scan the board for rows, columns, or $2 \times 3$ boxes that are already missing only 1 or 2 numbers. These are always the fastest, easiest cells to solve first!
2. Look for "Naked Singles": When looking at an empty cell, cross-reference its row, column, and box simultaneously. If 5 out of the 6 possible numbers are accounted for across those three constraints, the remaining number is a "naked single" and can be filled immediately.
3. Use Pencil Marks Constantly: Do not try to hold multiple possibilities in your head on harder $6 \times 6$ grids. Utilize pencil notes to list candidate numbers in empty cells—as you solve other parts of the board, erasing notes will automatically reveal new answers!
4. Scan by Number: Tap a number on the keypad to highlight all instances of that digit across the entire board. This makes it instantly obvious which rows or regions are still missing that specific number.
5. Cross-Hatching in Boxes: Pick a digit (e.g., number $3$) and trace its presence across adjacent rows and columns. This technique allows you to quickly eliminate placement options inside an empty sub-grid box down to a single remaining square.
