You want to generate your own grid? Or you already have a grid and would like a little help to unblock you? Then SolvoKu is perfect for you! When using hint mode, SolvoKu will not only add a number to the grid. The application will give you explanations of why you can put this number, of why you can remove candidates. Unfortunately for the time being when generating a grid you will get an easy grid most of the time, we are looking for solutions to allow you to select the level of difficulty you want.

Verdict

The call

The clearest difference is rating: ⋆Sudoku at 4.7 against SolvoKU's 4.3. ⋆Sudoku also leads on ratings volume (161K vs 9) and iOS requirement (15.0 vs 17.6). SolvoKU's advantage is update cadence (every 2 weeks vs monthly). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. ⋆Sudoku sells 1 one-off in-app purchase and SolvoKU sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

⋆Sudoku holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: ⋆Sudoku has 161K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 46% of ⋆Sudoku's written reviews are positive against 50% of SolvoKU's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

⋆Sudoku ships an update monthly, SolvoKU every 2 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
