Sudoku GameCenter
Classic, clear, endless
Free
A new puzzle every day for everyone — and from now on every game continues right
where you left it, on iPhone, iPad, Mac and Apple TV.
A sudoku that never repeats itself.
Every puzzle is generated when you start it, not pulled from a list. There is no
stock to run out of — and every puzzle is guaranteed to have exactly one
solution. Verified before you ever see it.
FIVE TIERS THAT MEAN SOMETHING
Difficulty here is not a random number. A solver plays each puzzle the way a
person would and measures which techniques it genuinely demands, from a simple
candidate to a forcing chain. What is labelled Expert really is expert.
HINTS THAT EXPLAIN
A hint does not just hand you a digit. It shows the next logical step and names
the technique behind it, so next time you spot it yourself.
EVERY DEVICE, EXACTLY WHERE YOU STOPPED
Start on iPhone, continue on Mac, finish on iPad. Your game follows you through
iCloud, notes and timer included.
DAILY PUZZLE
One puzzle a day, identical for every player worldwide, with its own leaderboard
and double points.
GAME CENTER
Leaderboards for total points, best times per tier and the longest daily streak.
30 achievements, from your first solve to a perfect week.
POINTS YOU CAN CHECK
After every puzzle you see exactly how your score came about: base value, time
bonus, deductions, streak bonus. Pencil notes are free — they are part of playing.
