How to play and improve
Read the instructions, tips, FAQ, and safety notes before placing ads near active gameplay.
Sudoku Mini is best for short logic practice: scan rows, columns, and 2×2 boxes, place only numbers you can justify, then replay for fewer errors.
How to play
- Press Start to generate a fresh 4×4 sudoku grid.
- Tap an empty cell, then choose a number from 1 to 4.
- Each row, column, and 2×2 box must contain 1, 2, 3, and 4 exactly once.
- Finish the grid to unlock the result panel and leaderboard submit form.
Scoring rules
- Score rewards a completed solve, faster time, fewer moves, and fewer wrong placements.
- A clean solve with no guessing is more valuable than a rushed solve with corrections.
- Your local best is stored only in the current browser.
Tips to improve
- Start with rows or boxes that already show two or three numbers.
- Check the row, column, and box before placing every number.
- If two cells can hold the same number, solve another constraint first.

FAQ
Do I need an account?
No. You can play without an account. Leaderboard submission uses a nickname only after a completed run.
Is this game safe for quick breaks?
Yes. It runs in the browser, has no download requirement, and keeps gameplay separated from ad areas.
How should I compare scores?
Compare several completed runs on the same device instead of treating one lucky result as your true baseline.
Solve the 4x4 grid by checking rows, columns, and boxes before each number. Your valid leaderboard result is based on score (pts).
How to approach each run
- Pause for a second before risky moves so you can see what the board will look like after the action.
- Track the constraint that matters most: empty space, safe cells, remaining moves, or tile position.
- Replay one board type several times instead of jumping around; pattern recognition improves faster that way.
