Sudoku - Brain Puzzle Games

Classic sudoku with quality-of-life features

The app delivers classic 9x9 sudoku and does so with a feature set that removes the main friction points of the genre. Pencil-note support lets players mark candidate numbers without committing, undo and redo handle accidental taps gracefully, and auto-save means a mid-puzzle interruption never costs progress. The hint system nudges toward the next logical step rather than handing over the answer, which preserves the satisfaction of solving. Weekly puzzle refreshes and daily challenges give returning players a reason to open the app beyond the static library. What the app does not offer is variant modes such as killer, diagonal, or irregular sudoku, so players seeking those formats will need to look elsewhere.

Stable performance across a large user base

Qualitative signals here are encouraging. A 4.79 average across 302,000 ratings suggests very few users are reporting crashes or persistent bugs, since unhappy players reliably drag scores down at that volume. The app was updated as recently as July 2026, indicating active bug-fix cycles rather than a maintenance-mode release. The 495 MB install size is notable for a number-grid puzzle game and points to heavier assets, likely animated backgrounds, themed visuals, or audio layers. That footprint is worth considering on storage-limited devices, but it does not appear to translate into sluggish gameplay based on the rating evidence available. Offline play is fully supported, which matters for commuters and travelers.

Free with unclear paywall boundaries

The base download is free, and a large puzzle library is accessible without paying anything. In-app purchases exist, but the App Store listing does not clearly itemize what sits behind a paywall, which means new users may encounter monetization prompts before they anticipate them. Common patterns in this category include ad removal, hint packs, and theme unlocks. The lack of upfront transparency about purchase scope is a genuine friction point. For players who can tolerate ads and use hints sparingly, the free tier appears substantial. Anyone who finds ads disruptive should budget for an unlock purchase whose price and scope they should verify in the current store listing before downloading.

Ad-supported model requires privacy label review

We do not independently test network traffic or permissions, and we will not invent findings. The authoritative source for this app's data practices is the App Store privacy label on the product page, which Apple requires developers to maintain. For a free, ad-supported puzzle game, it is reasonable to expect some level of advertising or analytics data collection, which is standard across this monetization model. Prospective users should review the privacy nutrition label before installing, paying particular attention to data linked to your identity and data used to track you across apps and websites.

Polished interface following sudoku conventions

The interface follows conventions that sudoku players will recognize immediately: a clean grid, a number pad, and clearly labeled tool buttons for notes, undo, and hints. Four difficulty tiers with explicit labeling make entry-point selection straightforward for players of any skill level. The visual design appears polished based on the app's long-term rating stability, as interface frustrations tend to surface in reviews over time. For accessibility specifics, including Dynamic Type support, VoiceOver compatibility, and color contrast options, the most reliable check is the App Store accessibility information section and recent user reviews from players who rely on those features.

Nearly seven years of active development

The maintenance record here is one of the app's clearest strengths. Released in November 2018 and updated in July 2026, this is a title with nearly seven years of continuous development behind it. Version 5.81.0 signals a developer that iterates regularly rather than shipping and stepping back. That longevity matters for a puzzle app because it suggests the library continues to grow, compatibility with current iOS versions is being maintained, and reported bugs are being addressed. Daily challenges and weekly puzzle refreshes further confirm that Oakever Games treats this as a live product rather than a static release.
