6×6, 8×8 & 10×10 Rules · Daily Sudoku Tips
The rules, the goal, and the rhythm of Mini Sudoku. Start with the 6×6 LinkedIn format, then try 8×8 and 10×10 when you want a longer puzzle.
Same goal as classic Sudoku: fill every row, column, and region with the required digits, no repeats. The grid is just smaller, so you finish faster. A 6×6 takes a few minutes once the patterns click.
Know the goal
Fill every row, column, and region with the required digits. No repeats.
Start with the givens
Use the numbers already on the board to spot the obvious singles first.
Narrow it down
Cross-check rows, columns, and regions to rule out digits until one is left.
Keep the streak going
Solve the daily Mini Sudoku to add to your streak. Miss a day and it resets.
Get unstuck
Use pencil marks for candidates and tap a hint when you stall.
After each placement, glance at the row, column, and region you just changed. New singles often appear right where you just played.
Ready to play? Open Mini Sudoku and switch between grid sizes whenever you want.
Scanning rows, columns, and regions trains you to spot details fast. Useful well beyond the puzzle.
Repeated practice with candidate pairs and singles makes the patterns easier to see in a few sessions.
A 6×6 Mini Sudoku takes a few minutes and pulls your attention off everything else for that span.
One puzzle a day adds up. The streak counter is there if you like the nudge — ignore it if you don't.
