Daily Sudoku
A fresh nine-by-nine number puzzle every day.
Three new sudoku puzzles every day, one Easy, one Medium and one Hard, the same for everyone. Every number can be worked out with logic, never a guess, and the harder puzzles ask for cleverer tricks. Your character stands by the number pad, thinking along with you and cheering every row you finish. Solve at least one a day to keep your streak going.
How to play
- Fill the grid so every row, every column and every 3 by 3 box has the numbers 1 to 9, once each.
- Tap a square, then a number on the pad. On a keyboard, move with the arrow keys and type 1 to 9.
- Turn on Notes (or press N) to pencil in the numbers a square might hold. Erase and Undo fix slips, and the Show mistakes switch colors wrong numbers pink if you want the help.
- There's a new Easy, Medium and Hard puzzle every day. Solve one a day to grow your streak; harder puzzles earn more coins, and you can replay a solved one just for fun.
Every way to play is equal here: touch, mouse and keyboard all move at the same top speed, so scores are fair whichever device you use.
Tips
- Look for a row, column or box with only one or two blanks, and fill those first.
- Pick one number and scan the whole grid for it: each box needs it once, so it often has only one place to go.
- Turn on Notes to pencil in candidates. When a square has only one candidate left, that's the answer.
- Every puzzle can be solved with logic alone, so you never need to guess.
