What's New in Smart Sudoku

4.0

February 26, 2026

• The progress bar now shows how far the puzzle has been solved. Previously, the display referred to the highest score achieved. • By quadruple tapping the background, the puzzle format can temporarily be switched to using "0" instead of "." for empty cells. This facilitates the exchange of puzzles on the Internet, e.g. Sudoku solvers. • Adjustments for iOS 26. Bug fix: In iOS 26, the "Check" button didn't work anymore.

Buggy

Candidates turned on. Tap a number (one of the candidates), tap a square. Square blinks red, remains empty. Turn number off and on again. Tap square again. Blinks red, remains empty. Use solve entire puzzle feature - square fills in with the number I was trying to enter. Delete app.

Simple and clean design

I was looking for a simple Sudoku app that would allow me to enter a puzzle and solve it like I would using paper and pencil. This one works like a charm with easy entry of the puzzle and straightforward user interface.

Smart sudoku

Excellent. Very simple to enter puzzles from the newspaper. Candidate numbers are displayed, allowing solutions to really tough puzzles to be solved without the laborious job of setting up candidates. I haven't found a tough inbuilt puzzle, but that's not what I got it for!
