User Reviews

Users praise Sudoku by Joseph for its fun jigsaw mode, intuitive controls, and flexible settings, along with a reliable, well-supported experience. The main drawbacks are intrusive ads and a desire for a one-time ad-free purchase, plus occasional input and OS compatibility quirks and finish-screen interruptions. Overall, it's a strong, enjoyable Sudoku app with room for polish and monetization improvements.

Intuitive interface with extensive customization options and adjustable difficulty.
Supports classic and jigsaw puzzles, plus landscape mode.
Free to play with non-intrusive ads and an optional ad-free purchase.
Long-term reliability and quick, helpful responses from the developer.

Cons

Ads can be intrusive; many users want a paid ad-free option.
Input issues (fat-finger errors and note-hint quirks) can hinder gameplay.
Occasional OS compatibility issues requiring updates.
Finish screen overlay/confetti after completing can obscure the board.

The new version is distributing. My eyes hurt. There may be settings to adjust the display but I don’t want to go through the hassle to figure it out. The old version had clean lines that provided an easy to use puzzle I could complete while waiting in line. This used to be one of my favorite APPS but you lost me as a user. I will be deleting.
