## Version history (last 5 releases)

### 1.3.1 — 2026-10-13

Hi! Thank you to everyone who plays Sudoku Brain and writes to us — we read every message.

### 1.2 — 2026-09-19

Hi! Thank you for playing Sudoku Smart, and for every message you send us — we read them all.

This update brings a new premium feature: auto notes. One tap, and every empty cell shows the numbers that can still go there, so your time goes into the puzzle instead of writing options down.

Premium now gives you more for the same price.

Have a great game, and see you at the next puzzle!

### 1.1.1 — 2026-09-08

A fresh new app icon and small visual improvements.

### 1.1 — 2026-09-05

Ever spent half an hour on a puzzle, only to find out it could never have been finished?

Sudoku Smart now catches that the moment it happens. If a move leaves part of the board impossible to fill, that number turns red — along with the squares it just closed off. Take it back and carry on.

We also fixed the language setting and added a one-time unlock, for everyone who'd rather not deal with subscriptions.

This update grew out of your feedback. Thank you for it.
