Five difficulty tiers with toggleable assistance tools

At its core, Sudoku.com delivers the classic 9x9 grid across five difficulty tiers, from beginner to expert, without fragmenting those modes into separate apps or paywalled sections. The assistance layer is the clearest differentiator: hints, auto-check, and duplicate cell highlighting can each be toggled on or off independently. A seasoned solver can strip every guardrail away, while a newcomer keeps all three active, and both experiences live inside the same interface without feeling condescending to either. Daily challenge puzzles add a light streak mechanic that rewards consistency. The execution is polished, the puzzle logic is sound, and the scaling genuinely works for someone who improves over months of regular play.

229 MB install supports consistent performance since 2017

A 229 MB install is notably heavy for a logic puzzle, and some of that weight appears to fund animated transitions and seasonal visual themes that contribute little to the solving experience itself. That said, the app's update cadence, with version 7.16.0 landing in June 2026 and a long history of regular releases since 2017, suggests Easybrain actively addresses stability issues rather than letting the product stagnate. The sheer volume of ratings, 1.8 million at a 4.76 average, implies most users encounter a smooth, crash-free session. Qualitatively, load times and grid responsiveness are consistent with a well-resourced developer maintaining a flagship title rather than an abandoned side project.

Free access to puzzles, paid tier removes ads

The free entry point is genuinely generous: core puzzle access across all difficulty tiers requires no purchase. The freemium structure does mean in-app purchases are part of the picture, and players who want uninterrupted, ad-free sessions will need to spend money or tolerate periodic prompts. For budget-conscious users, the free tier delivers real value. For those who find monetization friction disruptive to a focused puzzle session, a one-time paid sudoku app may offer a cleaner trade-off. The app never paywalls the puzzle itself, which keeps it competitive, but the cost of a truly frictionless experience is not zero.

Easybrain collects data typical of ad-supported apps

Easybrain is a sizable mobile publisher, and as with any free, ad-supported app, data collection practices are worth scrutinizing before installing. The App Store privacy nutrition label for Sudoku.com is the authoritative source on exactly which data types are collected and whether they are linked to your identity. We recommend reviewing that label directly on the product page before downloading. Typical signals to look for in ad-supported puzzle apps include identifiers used for advertising and usage data. Users who prefer minimal data exposure may want to weigh a paid, privacy-focused alternative against the free tier here.

Clean grid design with large tap targets

The interface is clean and low-friction, with a grid presentation that prioritizes legibility over decoration. Number input controls are large enough for comfortable tap targets, and the toggleable assistance tools mean the UI adapts to the solver rather than forcing a single experience on everyone. Thematic visual skins and animated transitions are present but optional in feel, even if they cannot be fully disabled. On accessibility, the app carries a 12-plus content rating and targets a broad audience, though users who rely on VoiceOver or dynamic type should verify current support directly, as puzzle grid apps vary considerably in how well they implement those features.

Nine years of regular updates show active support

Version 7.16.0 arrived in June 2026, nearly nine years after the app's March 2017 launch, which is a strong signal of sustained developer commitment. Easybrain has a track record of shipping updates across its puzzle portfolio rather than releasing and abandoning titles. The combination of a high rating, enormous review volume, and recent update cadence suggests both that critical bugs are addressed promptly and that the developer is invested in keeping the product competitive. For users who have been burned by puzzle apps that go dark after a year, Sudoku.com's maintenance history is one of its most reassuring qualities.
