### 5/5 — Wind Down Fun

*2025-04-05, version 1.2.5*

Sudoku is a great game to help me wind down at the end of the day.

### 2/5 — Poorly designed puzzles

*2018-01-31, version 1.2.5*

Not as good as other apps.  Some of the puzzles are poorly designed and can have multiple solutions, but the game will only accept one. Also occasional glitch where a cell becomes inactive and won't accept a number.

### 1/5 — Ad-Ad-Ad

*2016-05-15, version 1.0*

When I open to play it displays an ad for a different game that I can't close independent of the whole app.  Does me no good, since I never got to play sudoku at all.
