Mini Sudoku · Sudoku Puzzle Game
Mini Sudoku serves bite-size sudoku grids generated on the fly, each checked to have exactly one solution. Start with 4x4 grids, move up to 6x6 with fewer clues, and keep the shared clock alive by solving fast and avoiding wrong guesses.
How to play Mini Sudoku
- Tap an empty cell, then tap a number on the pad (or use arrows and keys 1-6).
- Each row, column and box must hold every number exactly once.
- Solve the grid to earn bonus time; a wrong number flashes red and costs 5 seconds.
Controls
Tap a cell, then a number — or arrows + keys 1-6.
Tips & tricks
- Start with the rows or boxes that already have the most numbers filled in.
- Don't guess: every grid can be solved by logic alone, and mistakes cost time.
