Verdict

The call

The clearest difference is ads: Sudoku at none against Sudoku ◆'s shown. Sudoku also leads on review sentiment (95% vs 75%). Sudoku ◆'s advantage is ratings volume (19K vs 1.1K). On price, rating, update cadence and in-app purchases there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Sudoku sells 11 one-off in-app purchases and Sudoku ◆ 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

On the App Store both sit at effectively the same score — 4.8 for Sudoku against 4.6 for Sudoku ◆.

Written reviews are what separate them: 95% of Sudoku's written reviews are positive against 75% of Sudoku ◆'s.

UpkeepUpdate frequency

Sudoku ships an update every 3 months, Sudoku ◆ every 6 months. The most recent releases landed on October 26, 2026 and October 28, 2026 respectively.
