Inkwell Sudoku: Classic Puzzle

Inkwell Sudoku is classic sudoku that feels like the puzzle page of your Sunday newspaper. Every day a fresh edition of The Inkwell lands on your desk: the Daily Puzzle leads the front page and the classic puzzles wait inside. Clip a grid, uncap your fountain pen and fill it in with your own ink. Big, clear numbers that are easy on the eyes, and a calm soundtrack.

HOW TO PLAY
• Fill every empty square with a number from 1 to 9
• Each row, each column and each 3×3 box must contain every number exactly once
• Tap a square, then a number; tap the same number again to erase it
• Turn on Notes (the pencil) to jot down candidates in small writing

THE DAILY PUZZLE
One daily sudoku for everyone: easiest on Monday, hardest on Saturday. Solve it to grow your streak while the front page counts down to the next edition, and solve it again for a better score.

FIVE LEVELS, FOR BEGINNERS AND EXPERTS
Easy, Medium, Hard, Expert and Master. Difficulty comes from the hardest technique a puzzle needs, never from guesswork: singles for Easy and Medium, locked candidates and pairs for Hard, triples, X-Wing and XY-Wing for Expert, Swordfish and XYZ-Wing for Master. Thousands of puzzles at every level, from your first sudoku to the hardest grids.

HINTS THAT TEACH
A hint shows the next logical step, names the technique and circles the square that matters, so you learn as you play. Every puzzle comes with three free hints. Made a mistake? The hint finds it first.

NO GAME OVER
Mistakes never end the game, and there are no lives or energy. A wrong number simply turns red (or stays hidden, if you prefer) and lowers your score a little. Undo is free and unlimited.

FAIR BY DESIGN
Every puzzle was checked by computer before it reached you: exactly one solution, solvable step by step with logic alone. Tap "Verify" in "How is it fair?" and your phone counts the solutions again. The game never changes the difficulty behind your back.

A REASON TO COME BACK
• Three daily missions, easy, medium and hard, plus a bonus for finishing all three
• Three stars for a perfect solve, best times for every level and detailed statistics
• Levels and XP
• Desks and inks that unlock as you play: Library, Garden Table, Rainy Window, Winter Cabin, Midnight Lamp; Jet Black, Burgundy, Emerald, Sepia, Violet, Teal, Antique Gold
• Halloween, October 23 – November 3: solve a puzzle and keep the Harvest Evening desk and the Pumpkin ink forever
• At most one reminder a day, and only if you want it

COMFORTABLE FOR EVERY PLAYER
Large numbers, highlighted rows, columns, boxes and matching numbers, auto-clearing notes, a "fill in all notes" option, handwritten or printed numbers, timer on or off. Plays offline, no Wi-Fi needed. Easy to read for seniors, relaxing for beginners, demanding for experts.

FREE, WITH NO FORCED ADS
Ads play only when you choose one: three more hints, double XP after a solve, saving a broken streak, swapping a daily mission, or trying a desk or ink for 24 hours. A small banner sits at the bottom in its own space and never covers the grid, the number keys or the buttons. No interstitials. Prefer no ads at all? A one-time Remove Ads purchase takes the banner away and grants every video reward instantly. Optional tips support the paper and unlock nothing else.

A fresh edition and a full pen. Your move.
