Sudoku - Classic Sudoku Puzzle

What it is

This is a Sudoku puzzle app from Oakever Games. It has been on Google Play since July 27, 2018, is free and carries an Everyone rating. It was last updated on October 29, 2026.

The goal is the standard one. You fill the grid with digits so each appears once in every row, column and mini-grid.

What it does well

The ratings lead the batch. The average is 4.75 from 3,075,558 ratings, and 90.6% are five stars. With 100,000,000+ installs, this is a game that most people finish happy.

The listing describes the app as ad-free and playable offline, and repeats this several times. Beyond that, the feature list is concrete: difficulty levels from easy to expert, a 16x16 grid for a bigger test, daily challenges and 100 new puzzles each week.

Smaller comforts are listed too. There is a timer, a dark mode, highlight options and sound effects. A guide tour at the start explains how to play, and the developer says the app can help you learn techniques.

Where it falls short

Look at the bottom of the rating split. 4.1% of people gave one star, but only 1.2% gave two, 1.0% gave three and 2.9% gave four. That shape suggests a small group had a bad time, but the listing does not say why.

The description is also heavy on repeated search-style phrases, which makes it hard to tell what is actually included. One example is the social sharing line, which names Google+, a service that is old news.

The listing does not say whether hints or undo are limited, or how puzzles are generated.

Who it suits

Both beginners and regulars should be fine. If you want a clean, quiet puzzle app, the ratings are in its favour.

The listing says players can learn Sudoku techniques from the app and that a guide tour is shown at first launch. It claims the game improves logical thinking and memory, which is a marketing claim the data cannot confirm. What the data does show is a very satisfied audience: 90.6% five stars and only 2.9% at four stars, which means most raters who like it, love it.

On practical grounds, the app is free, rated Everyone and updated regularly, and the developer lists social sharing and customisable gameplay tools. The text does not say how many puzzles are stored on the device for offline play.
