User Reviews

SumSudoku: Killer Sudoku is praised for being ad-free with puzzle ownership, thoughtful UI, and strong puzzle variety, plus weekly bonus content and a brain-boosting appeal. Recurring requests focus on UX: restore the swipe-to-sum feature, improve color contrast or allow color customization, and speed up note-entry. Overall, fans value quality and consistency and want small usability improvements while keeping the core experience intact.

Pros

Ad-free experience with puzzle ownership (no ads or aggressive microtransactions)
Well-designed UI and gameplay (easy pen/pencil markings, time tracking, clear difficulty levels, and restart to beat time)
Weekly bonuses and puzzle packs for ongoing content
Brain-boosting appeal—improves focus and feels calming/engaging
Trusted Conceptis brand with high-quality, varied puzzles and strong reputation

Cons

Removed swipe-to-sum feature; finger-drag to view sum combos is gone and users want it back
Color/visibility issues: tan grid lines are hard to see; new color schemes reduce differentiation; requests for color customization
Inefficient note-entry: tapping each number is slow; requests to fill multiple notes at once or drag across the keypad

Bring back the swipe for sum feature.

Great game, why did the finger drag on a box to view the number combos get removed?? Please add back - this was what made this app better than other similar ones
