## What is Sudoku Solver?

PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase.

Stuck on a sudoku? Type the grid in or point your camera at it, and in seconds you can see the full solution — or just the one hint you need, with the exact technique that finds it spelled out.

This is not another play-sudoku game. It is a solver and a tutor for the puzzles you already have: the one in this morning's paper, the book on your nightstand, the grid a friend swore was impossible. Where play apps give you a hint button that silently fills a cell, this app names the move — Naked Pair, Hidden Pair, Naked Triple, Pointing Pair, Box-Line Reduction, X-Wing, Y-Wing — and shows you why it works, so the next wall you hit is one you can climb yourself.

WHAT YOU GET
• Point your camera at a newspaper or book puzzle and the grid appears on screen in seconds — correct any misread digit with a tap before you solve
• Watch the solution unfold move by move, each step naming the technique that justifies it, with auto-play when you just want to watch the logic run
• Take only the next hint when you want to finish the puzzle yourself — it never spoils more than you ask for
• Study all seven solving techniques in the Learn tab, each taught on real example grids until you can spot the pattern unaided
• Candidates auto-filled in every empty cell, so your effort goes into logic instead of pencil-mark bookkeeping
• Generate fresh practice puzzles at five difficulty levels from Easy to Evil, each guaranteed to have exactly one solution — and every grid you solve is kept in history with a mini preview

PERFECT FOR
• Newspaper and magazine solvers who hit a wall on the weekend puzzle
• Beginners who know the rules but keep getting stuck halfway
• Improvers who want to finally learn X-Wing and Y-Wing properly instead of guessing
• Anyone who needs to check that a printed or hand-made puzzle really has a unique solution

WHY NOT JUST PEEK AT THE ANSWER KEY?
The answer key tells you what goes in the cell, never why. You fill it in, and next week you are stuck in exactly the same place. Step-by-step solving shows the reasoning at the precise point you got stuck — which is how you stop getting stuck at all.

PRIVATE BY DEFAULT
No account, no sign-up. Your puzzles, solving history, and progress are stored on your device, and camera scans are used only to read the digits off the grid.

PREMIUM (PURCHASE REQUIRED)
Sudoku Solver is unlocked with a subscription or a one-time purchase — weekly, yearly, or lifetime. Full access includes camera scanning, step-by-step solutions with explanations, all seven technique lessons, the puzzle generator, candidate auto-fill, and unlimited solving history.

Scan the puzzle that has been sitting half-finished on your kitchen table — you will have your next move in under a minute.

### 1/5 — Horrible

*2026-10-03*

This app won’t let me play one game to see how it works. No. It is trying to force me to subscribe for $20 a year. No way not an app that won’t let me play the game first to try it out.
