## What is Sudoku?

Sudoku Helper is for the puzzle you're already solving on paper or in another app.

Type in the starting numbers and the app shows you where each number can still go, so you can spot the moves that are forced.

SQUARE MODE
Tap a square and only the numbers that fit its row, column and 3x3 box stay active on the number pad.

NUMBER MODE
Pick a number and the whole board is coloured for it:
- Yellow: the number must go here
- Green: the number can go here
- Grey: blocked, or the square holds a different number
- Blue: the square already holds this number
Then tap a green or yellow square to place it.

MORE
- Undo any move, one step at a time
- Your game is saved automatically, so you can continue later
- A check when you start: the app tells you if your puzzle has no solution or more than one, so a typo doesn't leave you stuck
- Watch It Solve: see the yellow-square method solve a puzzle step by step, with play, pause, a speed slider and a timer
- A short How to Play guide and an example puzzle to get you started
- Light and dark mode

No ads, no accounts, no tracking and no internet needed. Everything stays on your device.
