Best Sudoku Ever
Classic Sudoku, clearly shown
Free · Designed for iPad. Not verified for macOS.
Classic Sudoku. Fill the grid, one number at a time.
Every row, column and 3x3 block needs the numbers 1 through 9, each exactly once. No luck, no timer pressure unless you want one — just working out where each number has to go.
3 DIFFICULTIES
• Easy — fewer blanks, more given numbers to start from
• Medium — a balanced solve
• Hard — the fewest given numbers, the most reasoning
HINTS THAT EXPLAIN THEMSELVES
A hint does not just point at a square — it names the number and tells you why it has to go there. "5 can only go here in this row." Press again for a different square. Watch one ad per hint; if no ad is available, the hint is given anyway so a slow connection never leaves you stuck.
SEE THE BOARD CLEARLY
Selecting a square lights up its row, column and block, so you can see every square that square affects. Squares holding the same number get a ring. Anywhere you have made a duplicate turns red immediately, ahead of every other highlight, so mistakes are never hidden.
NOTES
Turn on notes to jot down candidate numbers in small print. Confirm a real number and the same candidate clears itself from the notes in that row, column and block — no manual cleanup.
16 ACHIEVEMENTS
Clear your first puzzle, then 10, 25, 50, 100. Clear each difficulty, then all three. Clear Easy in 3 minutes, Medium in 6, Hard in 10. Solve without a single hint — Hard unaided is its own achievement. Solve using notes. Beat your own best time.
WHAT THE APP REMEMBERS
Every clear is kept with its difficulty, time, hints used and whether notes were used. Your best time for each difficulty and your total number of clears are shown in Settings, and the full history is there too.
A NUDGE EACH MORNING
An optional reminder at 8:00. Turn it off with one tap.
NO ACCOUNT
No sign-in, no sync service, no server. Your records are stored on your device.
ALREADY PLAYING?
Your clear history carries over untouched, and achievements unlock retroactively from puzzles you have already cleared.
The app is free and shows a banner ad. A full-screen ad appears when you leave a result screen, though not every time. Hints are supported by a short video ad, shown only after you agree to watch one.
