User Reviews

SumSudoku: Killer Sudoku is praised for its addictive, challenging puzzles without ads and useful gameplay features like sum combinations and pencil marks. Users appreciate the smooth interface and flexible in-app purchases based on difficulty levels. However, many mention the UI's poor contrast and difficult-to-read colors as significant drawbacks. Requests for color customization and reverting UI changes are common. Additionally, the automatic note removal feature and incomplete undo functionality frustrate some users. While free content is adequate initially, several desire more free levels without being pushed to buy additional puzzles.

Pros

No ads, providing an uninterrupted gaming experience.
Challenging and addictive puzzles with a good range of difficulties.
Helpful features like sum combinations and pencil marks enhance gameplay and logical deduction.
Smooth interface and user-friendly controls, including long press digit-first input.
Reasonable and flexible in-app purchase model with add-on packs split by difficulty.

Cons

UI issues with poor contrast and hard-to-see colors, especially yellow on beige, making numbers difficult to read.
No option to customize colors or revert to previous UI themes, causing visibility problems for many users.
Automatic removal of smaller note numbers in rows or columns after selection disrupts user note-taking, lacking an opt-out setting.
Undo functionality does not fully account for excluded sum combinations, causing inconsistent game states.
Limited free puzzles especially at higher difficulties, leading users to feel pressure to purchase more content.
