Lantern Sudoku - Unlimited
Quiet puzzles. Endless play.
Free · Designed for iPad. Not verified for macOS.
Settle into a quiet Sudoku game. Lantern creates fresh puzzles on your device, so there is always another board to explore.
TODAY'S CHALLENGE
Everyone plays the same puzzle each day, from Easy on Monday to Hell on Sunday. You get one try with no hints, and each wrong number adds 30 seconds. Compare times on the Game Center leaderboard, keep your streak going, and practise the puzzle again once your try is done.
FIVE LEVELS
Choose Easy, Medium, Hard, Expert, or Hell. Every generated puzzle is checked for a single solution and rated by the solving techniques it needs: Easy and Medium need only careful scanning, while Hell asks for X-Wings and XY-Wings.
LEARN AT YOUR PACE
Five fixed beginner lessons explain rows, columns, 3×3 boxes, and the controls through real play. Practise notes, erase, and undo with contextual guidance. Your regular puzzle stays saved, and lessons have no ads, timer or mistake limit.
MADE FOR FOCUS
A clean board, large number keys, pencil notes, undo, and automatic note clearing help you stay with the puzzle. Choose from 16 colour themes with a light or dark appearance, and adjust sound, haptics, and visual effects. iPad layouts adapt to portrait, landscape and Split View. The whole game is available in 13 languages.
PICK UP WHERE YOU LEFT OFF
Your puzzle, notes, undo history, and timer are saved on your device, and the home screen takes you straight back to it. No account is needed, and puzzles can be played offline.
A LITTLE LIGHT WHEN IT COUNTS
Gentle effects mark entries and completed rows, boxes, and puzzles. Subtle effects and the device's Reduce Motion setting offer a quieter experience.
CHALLENGE A FRIEND
Share a puzzle picture and a short code. Your friend can paste the code into Lantern to play the same puzzle and compare times.
Hints are available when you need them: three free hints a day, shared across all puzzles, with an optional rewarded ad for one more. A single banner ad sits at the foot of the home screen. There are no ads on the board, between puzzles, at startup, on app resume, or in Beginner.
