How to Play Sudoku Mini
Sudoku Mini is a compact 6×6 version of the classic Sudoku game. Every row, column, and 2×3 box must contain the digits 1 through 6 exactly once. The smaller grid makes for faster games but still demands the same logical deduction techniques — naked singles, hidden singles, and occasionally pairs — that power full-size Sudoku.
Sudoku Mini Rules
Fill the 6×6 grid with digits 1 through 6.
Every row must contain each digit exactly once.
Every column must contain each digit exactly once.
Every 2×3 box must contain each digit exactly once.
Pre-filled cells (givens) cannot be changed.
Step-by-Step Guide
- Step 1
Start with the row, column, or box that has the most given digits — fewer empty cells mean fewer possibilities.
- Step 2
Use naked singles: if a cell can only contain one digit (all others are ruled out by row, column, and box), write it in.
- Step 3
Use hidden singles: if a digit can only fit in one cell within a row, column, or box, place it there.
- Step 4
Toggle notes mode to pencil in candidate digits for cells with multiple options.
- Step 5
When you solve a cell, immediately check if it resolves any neighboring cells.
Strategy & Tips
Pencil notes are your best friend — use them liberally to track candidates.
Focus on digits that appear frequently in the givens; they are easiest to place first.
When two cells in a box share the same two candidates (a naked pair), eliminate those digits from other cells in the same unit.
Check your work after each digit — the green completion flash confirms a fully correct row, column, or box.

The grid is always 6×6 with 2×3 boxes. Difficulty is controlled by the number of given digits and solving technique required.
