Sudoku

Classic Sudoku, made to feel good on a phone.

Fill the grid so that every row, every column and every 3×3 box contains the numbers 1 to 9. No maths, just logic.

FAIR PUZZLES

• Every puzzle has exactly one solution

• Every puzzle can be solved by logic alone, you never have to guess

• Four levels: Easy, Medium, Hard and Expert

• Levels are graded by the solving techniques a puzzle needs, not just by how many numbers are given

• New puzzles are made on your phone, so you never run out

HELPFUL TOOLS

• Notes: pencil in the numbers a cell could still be

• Notes tidy themselves up when you place a number

• Undo as many steps as you like

• Hints when you are stuck

• Mistakes are marked right away and counted

• The row, column and box of your cell light up, along with every matching number

• See how many of each number are still left to place

MADE FOR PLAYING

• Your game is saved automatically, continue whenever you like

• A timer and best times for every level

• 16 colour themes, 8 dark and 8 light

• Sounds, haptic feedback and calm music that picks up as the board fills

• Separate volume controls for sound and music, or turn them off entirely

• Works offline

• No ads, no account, no in-app purchases

Start with Easy to learn the ropes, or go straight to Expert if you know your X-wings.
