User Reviews

Open Sudoku is praised for its extensive puzzle selection, open-source nature, and clean, ad-free experience with multiple input options and helpful features like notes and error undoing. Users appreciate its simple and attractive interface and the ability to import custom puzzles. However, recent updates have caused dissatisfaction due to UI changes that complicate gameplay, color scheme issues that reduce readability, persistent bugs with game state management, and unwanted sound effects. Many long-time users prefer earlier versions, lamenting that constant updates have negatively impacted the app's usability.

Pros

Great selection of Sudoku puzzles with multiple difficulty levels and thousands of free puzzles available.
Open source, ad-free, and no intrusive permissions, providing a clean user experience.
Multiple input methods, including manual puzzle input and configurable assistance features such as notes and highlighting.
Simple, attractive, and modernized interface that retains familiarity and usability.
Ability to import puzzles and features like 'undo to last mistake' that enhance gameplay and learning.

Cons

Recent updates have introduced UI changes that many users find less usable and cluttered, such as input/pencil tools positioned awkwardly and changes in color schemes making cells hard to read.
Bugs reported with completed games not updating properly and inconsistent detection of incorrect inputs during play.
Annoying audio feedback (beeps) for wrong values and intrusive new features reduce user enjoyment.
Frequent updates tinkering with a previously well-functioning and simple app disrupt user experience and preference for the older versions.

Recent reviews

Works well with a great selection of games.

This is a really really good implementation with good play. Recently got a rewrite and the play is really good. Hope to see continued evolution of this open source game app. Nice. The devs added a Xmas Challenge board viewable in December.
